Production of regenerated cellulose polymeric films from plantain pseudostem
Languages of publication
Regenerated cellulose was prepared from plantain pseudo stem obtained in Uyo, Akwa Ibom State. The pulp prepared with 12% NaOH had moisture content of 8.8% and a yield of 36.9% on the average. The pulp was bleached and exposed to air to form “white crumbs”. The aged crumbs was mixed with carbon disulphide at a controlled temperature of 30 °C to form cellulose xanthate (C6H9O4–S–SNa)n. This was then converted to regenerated cellulose by way of further treatment with tetraoxosulphate (VI) acid at a yield of 36.4%. This work has revealed that plantain pseudo stem waste can be converted to regenerated cellulose for diverse applications.
