DEVELOPMENT OF SEMI-INTERPENETRATING POLYMER NETWORK ELECTROLYTES OF POLYURETHANE AND POLYSILOXANE

摘要

A novel semi-interpenetrating polymer network (semi-IPN) electrolyte of polyurethane (PU) and polyether modified polysiloxane (PEMPS) with salt, LiClO_4, were developed by using a solvent-free reactive process. The dissolution of LiClO_4 in monomer and PEMPS was studied by using optical microscopy (OP), differential scanning calorimeter (DSC) and Fourier transform infra-red (FTIR) spectroscopy. The semi-IPN electrolytes of TPU/PEMPS were characterized by DSC and FTIR. The effect of PEMPS on the ionic conductivity of PU was also determined by using the modified LCR meter.
