摘要/Abstract

摘要： 采用原位聚合法制备了UHMWPE/PANI复合导电纤维。为提高复合纤维的电导率，采用了氧气等离子体对UHMWPE纤维进行预处理，研究了处理时间、反应功率和氧气压强等因素对复合纤维导电效果的影响，并用扫描电镜观察了等离子处理对UHMWPE纤维表面形貌的影响。结果表明：氧气等离子预处理增大了UHMWPE纤维的粗糙度，提高了其表面能，UHMWPE/PANI复合纤维的电导率增大，在功率90W，压强40Pa的处理条件下处理2min，复合纤维的电导率可以达到0.18S/cm。随着等离子体处理时间的延长、反应功率的提高及氧气压强的增大，复合纤维的电导率均呈现先增大后减小的趋势。

Abstract: UHMWPE/PANI composite fibers were prepared by in-situ polymerization in this paper. In order to improve the electrical conducting property of composite fibers, UHMWPE fibers were pretreated by oxygen plasma. The relationships between electrical conducting property of composite fibers and plasma conditions(i.e. exposure time, discharge power and oxygen pressure) were analyzed, and the influence of plasma treatment on the surface morphology of the fibers after treatment was investigated by scanning electron microscope(SEM). The results indicated that oxygen plasma treatment improved the electrical conductivity of the composite fibers due to the increased surface roughness and surface energy of UHMWPE fibers after plasma treatment. The electrical conductivity of the composite fibers reached to 0.18S/cm with the base fibers treated by oxygen plasma in discharge power of 90W, and oxygen pressure of 40Pa for 2min. The electrical conductivity of composite fibers increased firstly and then decreased with the increase of exposure time, discharge power and oxygen pressure of oxygen plasma.

Key words: oxygen plasma, PANI, UNMWPE fiber, in-situ polymerization, conductive fiber, surface morphology
