APPLICATION OF THERMAL SENSITIVE POLYURETHANE MEMBRANES FOR SELECTIVE SEPARATION OF SUBSTANCES WITH DIFFERENT SIZES
温敏聚氨酯膜用于不同尺寸物质的选择性分离

Thermal sensitive polyurethane(TSPU) membranes were prepared by wet phase inversion technique,and used for selective separation of substances with different molecular sizes.According to differential scanning calorimetry(DSC) and X-ray diffraction(XRD) analysis,it was found that the TSPU showed segmented structure and separate phase transition temperatures of soft segment phase and hard segment phase(the phase transition temperature of the soft segment phase was defined as the switch temperature,T_s).Polariz...
