点击翻译按钮获取中文摘要

The objective of the proposed research is to investigate the feasibility of using cryomilling to deagglomerate highly sintered carbon nanotubes, as an effective method of dispersing such nanotubes into polymer matrices. Cryomilling of nanotubes is a simple and scalable process but it has the risk of damaging the intrinsic properties of the nanotubes by interfering with pi-pi bonding interactions responsible for their properties. If successful, the proposed research will present a methodology for achieving composites with well-dispersed nanotubes that can be tested for mechanical, electrical and other essential properties for lightweight, high strength structural applications.
