Abstract

In the present study, we characterize internal structure of shape memory gel with Scanning Microscopic Light Scattering (SMILS), which is typically a dynamic light scattering system developed in our laboratory. It is specialized for analyzing the microscopic structure of gels having scanning as well as multi-angle facility. Transparent shape memory gel is prepared by solvent free technique using two monomers. The ratio of N,N-dimethyl acrylamide (DMAAm) and Stearyl acrylate (SA) is 3:1 in molar ratio. The mesh size of internal network structure of shape memory gel is determined by the SMILS and it is found in several nm in size. The diffusion coefficient is calculated and the critical temperature is observed where gel is changed its phase.
