摘　　要：为了考察膨润体系中乙酰乙酸乙酯(EAA)浓度和膨润时间对聚碳酸酯-聚丙烯腈-丁二烯-苯乙烯共聚物(PC-ABS)膨润效果的影响,通过EAA-氮甲基吡咯烷酮(NMP)-水体系对PC-ABS基板进行膨润处理,然后在70℃下,以H_(2)SO_(4)-MnO_(2)-H_(2)O体系为微蚀体系,对PC-ABS基板微蚀20 min。结果表明,当膨润体系中EAA体积分数为50%,膨润温度为55℃时,膨润5 min后PC-ABS可以获得合适的膨润度。通过此条件膨润及微蚀处理后的PC-ABS基板表面形成了分布均匀且致密的孔洞,基板表面与水的接触角减小,基板表面的亲水性增强,后续化学镀铜层与PC-ABS基板间的粘接强度达到4.03 N/cm,获得了理想的膨润和微蚀效果。To investigate the effects of ethyl acetoacetate(EAA)concentration and swelling time on the swelling performance of polycarbonate-polyacrylonitrile-butadiene-styrene copolymer(PC-ABS)in swelling system,the PC-ABS substrates were subjected to swelling treatment using EAA-N-methyl-2-pyrrolidinone(NMP)-H_(2)O system.Subsequently,employing an H_(2)SO_(4)-MnO_(2)-H_(2)O system as the micro-etching system,the PC-ABS substrates were micro-etched for 20 min at 70℃.Results showed that when the volume fraction of EAA in the swelling system was 50%and the swelling temperature was 55℃,the PC-ABS could obtain appropriate swelling degree after 5 min of swelling.Follow-ing this condition,swelling and micro-etching treatments led to the formation of evenly distributed and dense pores on the surface of the PC-ABS substrates.The contact angle between the substrate surface and water decreased,enhancing the hydrophilicity of the substrate surface.Consequently,the adhesive strength between the subsequently electroless copper plating layer and the PC-ABS substrate reached 4.03 N/cm,achieving the desired swelling and micro-etching effects.
