TIPS behavior for IPP/nano-SiO2 blend membrane formation and its contribution to membrane morphology and performance

doi:10.1016/j.cjche.2018.06.021

Abstract

Abstract: In the present work, the TIPS behavior of isotactic polypropylene (iPP)/di-n-butyl phthalate (DBP)/dioctyl phthalate (DOP)/nano-SiO₂ system and the competition relation between liquid-liquid phase separation and polymer crystallization are successfully adjusted by adding nano-SiO₂. The liquid-liquid phase separation temperature of the system increases with increasing nano-SiO₂ content. Besides, iPP crystallization temperature is also changed after adding nano-SiO₂. IPP/nano-SiO₂ blend hollow fiber microporous membrane is prepared via TIPS method. SEM photos show that the membrane exhibits mixed morphology combining cellular structure relating to liquid-liquid phase separation and branch structure originating from polymer crystallization. The relative weight of cellular structure first decreases and then increases with the increase of nano-SiO₂ content. Furthermore, porosity, connectivity among pores and pure water flux of the membrane first increase and then decrease with increasing nano-SiO₂ content. However, mechanical performance of the membrane is improved at all times with increasing nano-SiO₂ content.
