STUDIES ON PREPARATION AND PROPERTIES OF CONTINUOUS CARBON NANO-TUBE FIBERS SPUN FROM CNT ARRAY
摘要
Abstract
Carbon nanotubes (CNTs) can be assembled into continuous CNT fiber, for example, by the method of array spinning. In this article, effects of several assembly parameters during the spinning process were investigated , such as ethanol infiltration, fiber diameter and twist level. They all have influences on CNT arrangement and the mechanical properties and electrical conductivity of fiber. The results show that ethanol infiltration can densify CNT fibers significantly and thus enhance them. After infiltration, the elastic modulus, tensile strength and electrical conductivity of CNT fibers are increased by 121% , 67% and 26% , respectively. The optimal fiber diameter of 7 ~8μm can be achieved by adjusting the width of the drawn film. For the infiltrated CNT fibers a certain decrease in twist angle does not affect the mechanical and electrical performances, making it possible for the large-scale production.关键词
