【摘要】 高分子材料化学镀中,通常必须对高分子材料进行表面改性,以提高高分子材料表面的极性,增强对金属离子的附着能力。探讨了一种以丙烯酸共聚物的溶液作为高分子材料表面改性方法的可行性。研究表明,聚丙烯酸酯共聚物的溶液在对ABS进行表面处理时,在ABS表面形成含有含氧官能团结构的新表层,该新表层能够对钯离子产生良好的附着力。同时研究表明,在化学镀镍过程中,镀层在经过改性后的表面生长均匀,致密性好,表明表面具有良好的可镀性。更多还原

【Abstract】 In the polymer surface electroless plating,the surface modification of the polymer should be made to improve the adherence of metal ions,particularly the Pd2+,to the polymer surface.In this paper,the use of polyacrylates as ABS surface modifier before electroless nickel plating was studied.The result revealed by the use of polyacrylates as modifier formed a new functional surface layer on ABS surface,which showed good adherence with Pd2+,the latter was reduced to Pd0 by electroless bath before nickel plating.Electroless nickel plating grew well on the so modified surface,and deposited layer grew uniformly.更多还原
