Publisher and Date:(Polish Academy of Sciences, 2012)The purpose of this study is to discuss the role of kappa-carrageenan (?-car) in the drying and swelling of polyacrylamide (PAAm)-?-car composite. The fluorescence intensity of pyranine increased and decreased as drying and swelling time were increased respectively for all samples. The desorption coefficient Dd decreased as ?-car contents were increased for a given temperature during drying. However cooperative diffusion coefficient Ds increased as ?-car contents were increased during swelling at ...
