核壳型碳纤维毡@聚苯胺复合材料的制备及其介电性能
Preparation and dielectric properties of core-shell structural carbon-fiber felt@polyaniline composite
摘要
Abstract
Polyaniline(PANI)was grown on the surface of carbon fiber felt(CFF)through in-situ chemical oxidative po-lymerization to obtain a core-shell structural composite.The composite was subsequently encapsulated with polydimeth-ylsiloxane.The influence of reaction condition on the structure and properties of the resultant composite was explored.The results indicated that the PANI particles were uniformly decorated on the surface of carbon fiber,resulting in a color change from black to dark green.Contact angle and surface energy analysis indicated that the surface energy of the com-posite was greatly reduced after encapsulation,though there was no obvious difference between the CFF@PANI compos-ite and CFF.The presence of the core-shell structure enhanced the interfacial and dipole polarization significantly because of the multi-interface structure and interfacial effects.A high dielectric relaxation behavior was achieved for the compo-site,thus improving its capacitance and voltage-sensitive effects significantly.关键词
