The purpose of this study is to discuss the role of kappa-carrageenan (κ-car) in the drying and swelling of polyacrylamide (PAAm)-κ-car composite. The fluorescence intensity of pyranine increased and decreased as drying and swelling time were increased respectively for all samples. The desorption coefficient, D_{d}, decreased as κ-car contents were increased for a given temperature during drying. However, cooperative diffusion coefficient, D_{s}, increased as κ-car contents were increased during swelling at a given temperature.
