Abstract


The flexible superhydrophobic thermoplastic polyurethane(TPU) porous material was prepared by heat-induced phase separation method with two cooling steps. The influence of the preparation process on the microstructure of the material was discussed in depth. The microstructure, hydrophobicity and specific surface area of porous TPU materials were analyzed in detail. The surface wettability, separation selectivity, saturated adsorption capacity and adsorption rate, mechanical properties, environmental adaptability and cyclic properties of porous TPU materials were studied.The results show that the TPU-8% porous monolithic material prepared by heat-induced phase separation method shows good performance when the polymer concentration is 8%, the phase separation temperature is 0°C, the phase separation time is 30min, and the mixing solvent ratio is 9:1.
