摘要

Abstract

Herein

isotactic polypropylene films with small

-nucleating agent content were fabricated

via

a melt-extrusion-stretched technology with intended “shear-free” in barrel and die. Compared with neat films

the tensile strength

elongation at break and strain energy density at break of

PP film with 0.05 wt%

-nucleating agent are significantly improved by 13.8%

39.6% and 90.6%

respectively

indicating the simultaneously enhanced toughness and strength. Additionally

the

-crystal content gradually increases with increasing

-NA content

while the relative total daughter content of

- and

-crystal exhibits opposite tendency. Moreover

nucleation and crystal growth induced by various

-NA contents are different. This work proves an efficient strategy to enhance mechanical properties of isotactic polypropylene film

via

controlling elongation flow and addition of appropriate

-NA content.
