The electrorheological (ER) suspensions containing the powders of silicone aluminum oxygen gel compilihentioned with PMMA and silicon oil were prepared. The viscosity of these suspensions and their influencing factors, such as electric field strength and particle concentration, were detected. By use of rare earth as agent to dope the samples, the experimental results show that, with the increasing of field strength and particle concentration, ER effect changes.
Mechanical properties of poly (vinyl chloride) film doped with micro rare earth neodymium are improved notably. Its tensile strength increases from 36 1 to 52 9 MPa, while its flexibility is increased significantly by adding active silanol extracted from water glass. Both ultraviolet and microwave crosslinking result in samples with satisfactory mechanical properties, and the flexibility of the microwave crosslinked samples is much higher than that of the ultraviolet crosslinked ones.
