Isotactic polypropylene (iPP) microporous membranes were prepared via
thermally induced phase separation (TIPS) method. IPP, paraffin oil and acetone
were used as the polymer, diluent and extractant, respectively. The effects of
polymer concentration and quenching bath temperature on the membrane porosity
and mechanical properties were investigated. With the increase of polymer
concentration, the porosity of membrane decreases and the tensile strength
increases as well. When quenching at same coarsening time, the porosity
obviously increases with the increase of bath temperature
