Abstract
Shape memory gel is a much interesting and attractive material for the application to the soft systems. The typical gel is the polymer, which is composed of acrylic acid (AA) and stearyl acrylate (SA). The polymers are cross-linked by N, N' methlenebis. The restoration characteristic depends upon the ratio of AA and SA as well as the amount of the cross-linker. We carried out the fundamental experiments on the gel to understand the restoration properties and to optimize the performance. The optimized gel was found in the proper ratio and amount. An elastic modulus and temperature dependency were considered.
