The crystallization of uniaxial hot drawn syndiotactic polystyrene/multi-walled carbon nanotube (sPS/MWCNT) nanocomposite films was studied by FTIR spectroscopy.The effects of MWCNT content,draw ratio and drawing temperature on the sPS crystallinity were investigated.The sPS/MWCMT nanocomposite films show reduced crystallinities with the increase of MWCNT content.In addition,with the increase of draw ratio,both the pure sPS and the sPS/MWCNT nanocomposite drawn films exhibit increased crystallinity.The effect of drawing temperature on the sPS crystallization is complex.In a temperature range of 100-135 ℃,the crystallinity decreases with drawing temperature,whereas it increases at 140 ℃ for both pure sPS and its nanocomposite films.
