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.

本研究的目的是探讨利用低温碾磨对高度烧结的碳纳米管进行脱团的可行性，作为一种将碳纳米管分散到聚合物基体中的有效方法。纳米管的低温研磨是一个简单且可扩展的过程，但它有破坏纳米管固有特性的风险，因为它会干扰纳米管的pi-pi键相互作用。如果成功的话，这项研究将提供一种方法来获得具有分散良好的纳米管的复合材料，这种复合材料可以用于测试轻量化、高强度结构应用的机械、电气和其他基本性能。
