The process of production of filtration mats of various thickness from PVC and PVDF polymers by the electrospinning method is presented in the paper. Filtration of nanoparticles and submicron particles is an important problem in industry and health protection systems, in particular in air-conditioning and ventilation appliances. This problem can be effectively solved by application of non-woven fibrous filtration mats. The experimental investigations of mechanical properties of nanofibrous filtration mats produced by electrospinning and the measurements of removal efficiency of submicron particles from flowing gas have indicated potential usefulness of these nanomats for gas cleaning of air-conditioning systems and/or ventilation ducts. The experimental results obtained for cigarette smoke of a mass median diameter of about 1 μm, used as test particles, have shown that nonwoven nanofibrous filtration mats produced by electrospinning have a good filtration efficiency for nano- and submicron particles, owing to a pressure drop similar to HEPA filters. Particles of this size are particularly difficult to be removed from the flow by a conventional method, for example, by a cyclone or electrostatic precipitator.

In this communication, hollow bioactive glass (BG) nanofibers were fabricated via a single-nozzle electrospinning method. The morphology of the prepared hollow BG nanofibers was observed by SEM and TEM, and the results showed that BG nanofibers had a continuous hollow interior. The hollow BG nanofibers were incubated in simulated body fluid (SBF) to investigate their apatitemineralization ability, and the result showed that after incubation for 6 h a flower-like apatite was observed on the surface of hollowBGnanofibers, and the Fourier transform infrared (FTIR) result further confirmed the formation of apatite. The results suggested that hollow BG nanofibers could be used for drug delivery and bone regeneration applications due to their unique hollow structure and bioactivity.

The goal was to electrospin 2-hydroxyethyl methacrylate - based biocompatible polymers and prepare submicron fibres (nanofibers) for biomedicinal applications. Syntheses of poly(2-hydroxyethyl methacrylate) (HEMA) and its copolymer with 2-ethoxyethyl methacrylate (EOEMA), and their characterization by viscometry and molecular weight are described. Their relation to electrospinning is discussed. Electrospinning of HEMA homopolymer from water-ethanol is successful for molecular weights 6.31 × 105 and 1.80 × 106 g/mol. Electrospinning of HEMA/EOEMA copolymers is feasible from ethanol. [...]

In this study, a solution of dibutyrylchitin (DBC)/polylactide (PLA) blend micro and nanofibres were successfully fabricated using blends of 2,2,2-trifluoroethanol (TFE) as solvents. Fibres were produced from the solutions by electrospinning. The DBC/PLA blend solutions in various ratios were studied for electrospinning into micro/nanofibres. The morphology of the micro and nanofibres was observed by scanning electron microscope (SEM). The biggest diameters of DBC/PLA fibres were obtained for the blended microfibres in ratios of 10/90 and 25/75. The smallest diameter was observed for pure polymers. The antibacterial properties were examined for materials obtained by electrospinning. In the experiments, materials with antibacterial properties were made. It is likely that the electrospun micro and nanofibres will be used in the native extracellular matrix for tissue engineering.

Bone is a composite tissue composed of an organic matrix, inorganic mineral matrix and water. Structurally, bone is organized into two distinct types: trabecular (or cancellous) and cortical (or compact) bone. Cortical bone is highly organized, dense and composed of tightly packed units or osteons whereas trabecular bone is highly porous and usually found within the confines of cortical bone. Osteons, the subunits of cortical bone, consist of concentric layers of mineralized collagen fibers. While many scaffold fabrication techniques have sought to replicate the structure and organization of trabecular bone, very little research focuses on mimicking the organization of native cortical bone. In this study we fabricated three-dimensional electrospun cortical scaffolds by heat sintering individual osteon-like scaffolds. The scaffolds contained a system of channels running parallel to the length of the scaffolds, as found naturally in the haversian systems of bone tissue. The purpose of the studies discussed in this paper was to develop a mechanically enhanced biomimetic electrospun cortical scaffold. To that end we investigated the appropriate mineralization and cross-linking methods for these structures and to evaluate the mechanical properties of scaffolds with varying fiber angles. Cross-linking the gelatin in the scaffolds prior to the mineralization of the scaffolds proved to help prevent channels of the osteons from collapsing during fabrication. Premineralization, before larger scaffold formation and mineralization, increased mineral deposition between the electrospun layers of the scaffolds. A combination of cross-linking and premineralization significantly increased the compressive moduli of the individual scaffolds. Furthermore, scaffolds with fibers orientation ranging between 15° and 45° yielded the highest compressive moduli and yield strength.

Comparative statistical analysis of the infiuence of processing parameters, for electrospinning (ES) and solution blow spinning (SBS) processes, on nanofibrous poly(L-lactic acid) (PLLA) material morphology and average fiber diameter was conducted in order to identify the key processing parameter for tailoring the product properties. Further, a comparative preliminary biocompatibility evaluation was performed. Based on Design of Experiment (DOE) principles, analysis of standard effects of voltage, air pressure, solution feed rate and concentration, on nanofibers average diameter was performed with the Pareto’s charts and the best fitted surface charts. Nanofibers were analyzed by scanning electron microscopy (SEM). The preliminary biocompatibility comparative tests were performed based on SEM microphotographs of CP5 cells cultured on materials derived from ES and SBS. Polymer solution concentration was identified as the key parameter infiuencing morphology and dimensions of nanofibrous mat produced from both techniques. In both cases, when polymer concentration increases the average fiber diameter increase. The preliminary biocompatibility test suggests that nanofibers produced by ES as well as SBS are suitable as the biomedical engineering scaffold material.

Electrospinning is a simple and efficient method of polymer fibers fabrication. In this method electrostatic forces are used to obtain fibers or particles with different morphology and size from micro- to nanometers. Nowadays more than 100 polymers, natural or synthetic ones, have been successfully electrospun into fibers. Electrospinning process is affected by various different parameters such as viscosity, polymer’s average molecular mass, voltage, flow rate, etc. Electrospinning of biopolymers, alginate and chitosan, is difficult. Both of these polymers are non-toxic, biodegradable and possess antibacterial properties, all these properties are desirable in biomedical applications. In the presented work an influence of parameters of electrospinning on process of obtaining of alginate and chitosan fibers was presented and discussed. Alginate fibers were obtained with poly(ethylene oxide), while chitosan fibers were prepared from trifluoroacetic acid and dichloromethane solution.

Elektroprzędzenie (ang. electrospinning) jest prostą i efektywną techniką pozwalającą na produkcję włókien polimerowych. W metodzie elektroprzędzenia siły elektrostatyczne są używane do produkcji włókien lub sfer o różnej morfologii i rozmiarach w skali mikro- i nanometrów. Obecnie ponad 100 polimerów, naturalnych i syntetycznych, zostało z powodzeniem wytworzonych w procesie elektroprzędzenia. Na proces elektroprzędzenia wpływa wiele parametrów, między innymi lepkość roztworu, średnia masa cząsteczkowa polimeru, przyłożone napięcie, prędkość przepływu. Elektroprzędzenie biopolimerów, alginianu i chitozanu jest wyzwaniem. Te dwa naturalne polimery charakteryzują się niską toksycznością, biodegradowalnością i właściwościami antybakteryjnymi, co jest szeroko wykorzystywane i pożądane w aplikacjach biomedycznych. W prezentowanej pracy omówiono wpływ warunków elektroprzędzenia na proces otrzymywania włókien alginianowych domieszkowanych poli(tlenkiem etylenu) i włókien chitozanowych otrzymywanych z roztworu kwasu trifluorooctowego i dichlorometanu.
