紫外引发点击反应高效增强碳纳米管纤维的机械强度
Highly-efficient improvement of the mechanical strength of carbon nanotube fibers via UV-initiated click reaction
摘要
Abstract
To produce CNT fibers with stable mechanical performance, a highly-efficient and facile thiol-ene click reactionwas used to functionalize the carbon nanotube ( CNT) fibers. The effects of the functionality and content of mercaptans and other reaction conditions on the performance of the functionalized CNT fibers, and the enhancement mechanism were studied. The results showed that without damaging the structure of the CNTs, a crosslinked structure between individual carbon nanotubes was formed. Several mercaptans with different functionalities were used to functionalize the CNT fibers via the thiol-ene click reaction between the double bond of pristine CNT fibers ( PCNTs) and the thiol groups. The tensile strength of the functionalized CNT fibers increased with the increase of thiol functionality, and continued twisting could further improve the tensile strength. The tensile strength of the functionalized and twisted CNT fiber was 191.7％ higher than the PCNT. This facile method about improving the mechanical strength of CNTs fibers may be of great significance for their wide application.关键词
