Abstract

We recently discovered that a block co-polymer constructed with side chain crystalline monomer and solvent compatible monomer (Side Chain Crystalline Block Co-Polymer: SCCBC) have an ability to decrease viscosity of concentrated polyethylene (PE) particle suspension system incredibly. This suspension system shows the Thermal Rheological (TR) Fluid effect, which is reversible temperature dependence of viscosity, with increasing temperature and the viscosity increases to almost the original value of the suspension without the SCCBC. In this time, we have investigated the SCCBC as a surface modifier of PE porous membrane. We investigated a permeation rate of this membrane by measuring the conductivity of Li ion and of their temperature dependence. In this investigation we found a transition temperature that the conductivity changed discontinuity. This function is able to applicable to a Li ion battery.
