摘　　要：通过低温等离子体表面处理对丙烯腈⁃丁二烯⁃苯乙烯(ABS)表面进行刻蚀;以乙烯基三甲氧基硅烷、γ⁃巯丙基三甲氧基硅烷、γ⁃氨丙基三乙氧基硅烷为主体的无钯敏化、活化液对ABS进行表面镀镍,通过傅里叶变换全反射红外光谱(ATR⁃FTIR)、接触角测量仪和扫描电子显微镜(SEM)等探究了电镀ABS的性能,并根据GB/T 9286—2021,用90°黏合强度测试法测试塑料与金属层之间的黏附牢固程度。结果表明,当处理时间为300 s、功率为600 W时,ABS电镀预处理效果最佳,此时结合强度达到0.94 kN/m。The surface of acrylonitrile⁃butadiene⁃styrene(ABS)resin was etched through non⁃thermal plasma surface treatment.A palladium⁃free sensitization and activation solution composed of vinyltrimethoxysilane,(3⁃mercaptopropyl)trimethoxysilane,and 3⁃triethoxysilyl⁃1⁃propanamine was used for the surface nickel plating of ABS.The properties of electroplated ABS were investigated using Fourier⁃transform total reflectance infrared spectroscopy,contact angle mea⁃suring instrument,and scanning electron microscope.A 90°adhesive strength testing method was adopted to measure the adhesion between the plastic and metal layer according to the national standard GB/T 9286—2021.The results indi⁃cated that the optimal pretreatment effectiveness was achieved for ABS electroplating at a treatment time of 300 s and a power of 600 W.As a result,the substrate bonding strength reached 0.94 kN/m.
