Abstract

The elastic behavior of aqueous gelatin gel was studied in the immediate vicinity of the sol-gel transition point. It was found that the elasticity of gelatin gel consists of two parts, ‘background elasticity’ and ‘critical elasticity’. The background elasticity does not vanish in the sol phase. The site-bond percolation model was found to be applicable to the critical elasticity. Values of the elasticity exponent obtained in this study were 1.71 for the concentration dependence and 1.86 for the temperature dependence. The results are in good agreement with the theoretical prediction for the three-dimensional percolation system.
