| Summary: | A microrheological method is employed for the first time to continuously and
undisturbedly monitor variations of viscoelasticity of magnetorheological elastomers
(MREs) based on silica-coated carbonyl iron particles (SiCIPs)-filled silicone during the
curing process. Results indicate that the elasticity of MREs dramatically increases with
increasing magnetic field intensity, which is much more significant in comparison with the
slow process of silicone curing at 25 % and 40 % SiCIPs. The formations of chain-like
structure of SiCIPs and cured network of silicone are recognized, both contributing to the
rheology of MREs, suggesting the possibility of developing a facile method for adjusting
the rheology and fixing the structure of a wide range of MREs by applying magnetic field
during the curing of matrix.
