Since TPX is a polymer with high degree of crystallinity, solid-liquid demixing should be taken into consideration during membrane formation. By using suitable coagulant, such as propanol, particulate TPX membranes with inter-connected pores can thus be successfully fabricated. By adjusting the coagulation environment, the pore size of the porous TPX membrane can be tailored. Experiments were performed to evaluate the performance of the prepared membranes in pervaporation and osmotic distillation. The results indicate that the performance of the microporous TPX membranes prepared in the present work is comparable to that of the commercial PTFE membranes.application/pdf1348536 bytesapplication/pdfzh-TW國立臺灣大學化學工程學系暨研究所聚四甲基一戊烯疏水性顆粒膜滲透蒸發滲透蒸餾poly(4-methyl-1-pentene)hydrophobicparticulate membranepervaporationosmotic distillationreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/9311/1/902214E002032.pdf
