聚苯胺/纳米镍复合材料的制备及屏蔽性能
Preparation and shielding properties of polyaniline/nano nickel composite materials
摘要
Abstract
Polyaniline/nano-nickel composites of different mass ratio were prepared by in-situ polymerization of aniline in the presence of nano-nickel ,using ammonium persulfate (APS) as oxidant ,citric acid (C6 H8 O7 ) as dopant and polyethylene glycol octyl phenyl ether (OP-10) as dispersant .The results indicated that there is no chemical interaction between polyani-line and nano Nickel in the composite .And network structure was formed based on the ad-sorption of nano-nickel onto rod-like polyaniline .The composite films were prepared with polyaniline/nano-nickel composite powder as fillers and water-based polyurethane as matrix . The conductivity of the composite and electromagnetic shielding performance of the film with different mass ratio were investigated .The electrical conductivity of the composite reached 1 .82 S/cm when the mass ratio of nano-nickel to aniline was 1:3 .The composite film dis-played the optimum shielding property when the mass ratio of nano-nickel to aniline was 1:3 .The shielding effectiveness increased to 66 .5 dB in the frequency range of 3 .6 to 5 .36 GH when the filler content was 25% .关键词
