摘要:
以纳米石墨微片作为导电填料,高分子树脂作为粘结剂,制备高导电性复合涂料,研究其电磁屏蔽等相关性能.探讨纳米石墨微片、基体树脂、表面改性剂、溶剂,以及分散工艺和施工工艺对导电涂料的导电性及电磁屏蔽效能的影响.结果表明,质量分数为30%的纳米石墨微片,质量分数为5%的阳离子分散剂,质量分数为65%的丙烯酸树脂,以及适量混合溶剂为较佳配方,而以机械研磨辅以超声分散是较好分散工艺.通过该法制备得到的导电涂料,其涂膜的表面电阻率低至0.6Ω.m-1,电磁屏蔽效能达到38 dB(1.5 GHz).
Abstract:
A conductive coatings based on graphite nanosheets(GNs) and resin has been developed.The preparation technology and the properties of the coatings were investigated.The effect of graphite nanosheets loading,matrix resin,surfactant,solvent,dispersion process,and coating process on the conductivity and shielding effectiveness of the coatings were discussed.The results showed the best component for the coating is: the loading of graphite nanosheets,cationic dispersant and thermoplastic acrylic resin were 30%,5% and 65% by mass ratio respectively.The best dispersion process is: shear mixing with the aid of sonication.The surface resistivity of the conductive coating was only 0.6 Ω·m-1,and its shieldind effectiveness at 1.5 GHz was shown up to 38 dB.
