Preparation of Porous Poly(ether ether ketone) Membranes via Thermally Induced Phase Separation

The porous membranes of poly(ether ether ketone)(PEEK) were prepared by thermal(induced) phase separation method in PEEK/ diphenyl sulfone system and PEEK/ diphenyl ketone system.The possibility to make porous membranes that tolerate high temperature and solvents was studied by thermally induced phase separation(TIPS) method.The relation of solubility(expressed by interaction(parameters)) was calculated and analyzed.The polymer composition effect on the porous structure was also(discussed).
