研究了气相生长碳纳米纤维增强液晶聚合物（LCP）复合材料。通过掺入 5 wt% 的纳米纤维，LCP 的表面电阻率降低了 11 个数量级以上。还研究了不同频率下的电磁干扰屏蔽效能（SE）。该复合材料表现出高达 41 dB 的 SE。系统的屏蔽机制主要是反射和多次反射。复合材料的热导率并未因纳米纤维的加入而显着提高。 (c) 2004 Elsevier Ltd. 保留所有权利。
Vapor grown carbon nanofiber reinforced liquid crystal polymer (LCP) composites were studied. The surface resistivity of LCP was lowered more than 11 orders of magnitude by incorporating 5 wt% of nanofibers. The electromagnetic interference shielding effectiveness (SE) at different frequencies was also studied. The composites were shown to exhibit up to 41 dB of SE. The shielding mechanism of the system was mainly reflection and multiple reflections. The thermal conductivity of the composites showed no significant enhancement with the inclusion of nanofibers.
