Abstract

Interpenetrated polymer network (IPN) of gelatin (Git} and sodium polyalginate (Alg) is studied to prepare Alg gel, which is expected to be more uniform than that prepared directly at high added salt (NaCl) concentrations, C_s. The mixed solution and IPNs are homogeneous at lower C_s. It was found that the mixed solution get phase separated around C_s =0.35M. The gels made from the phase separated solution were also investigated. The roughness of Alg gels prepared via IPN and directly at higher C_s is almost the same. It can be summarized that the phase separation was brought by higher C_s and it is not suitable to prepare uniform Alg gels with high.er C_s. It was pointed out that the Alg gels prepared with lower C_s via IPN shows narrower elastic modulus distribution than the higher ones.
