DEVELOPMENT OF A GELATION MODEL FOR METHYL CELLULOSE HYDROGELS

摘要

The development of a gelation model for methylcellulose (MC) hydrogels is presented. The heat of gelation for aqueous solutions of different concentrations of MC SM4000 was measured using micro-DSC. Different mathematical formulations for modeling the experimental data were considered. The necessary constants were obtained empirically. Further analysis was performed to predict the total heat, the degree, and the rate of gelation. The effect of MC concentration on these parameters was investigated and discussed.
