Abstract

The kinetics of swelling of spherical poly(dimethyl siloxane) (PDMS) composite networks in cyclohexane has been studied. The PDMS composite gels contain magnetite and iron particles built in the network either in randomly distributed form or in chain-like structure. The composite gel becomes anisotropic in the terms of both, mechanical and swelling properties. As a consequence the swelling kinetics can be characterized by direction dependent relaxation time. The swelling kinetics of these samples has been compared to that of pure PDMS gels. It was found that Li–Tanaka theory can be applied to describe the swelling kinetics of PDMS network.
