摘　　要：经熔融挤出的全氟磺酸膜,经过后期的单向拉伸会产生单向取向,从而展现出各向异性,不利于膜性能的均一化。通过改变膜的挤出条件研究生产过程中造成膜各向异性的原因,并通过热处理方法探究消除该各向异性的途径。Perfluorosulfonic-acid membrane produced by melt extrusion technique shows unidirectional orientation property after unidirectional stretching,and has the character of anisotropy which is against the uniformity of membrane's properties.The cause of the anisotropy of membrane in production is researched by changing extrusion conditions in this article,and the methods of releasing the anisotropy through heat treatment are explored as well.
