摘　　要：聚合物粉体材料经过金属化处理后,不仅呈现出金属的外观和硬度,且易于焊接,有时还可作为金属制品的替代品。由于非活性基底材料(如塑料、玻璃、陶瓷等)的表面活性较低,其性能与金属存在显著差异,因此仅靠物理沉积吸附无法实现表面金属化。通过在尼龙12(PA12)粉体表面原位构筑活化位点,吸附催化剂粒子并催化化学镀,实现制备金属颗粒/PA12复合粉体,阐明了PA12粉体表面吸附催化位点和催化化学镀的机理。After metallization,polymer powder materials not only exhibit the appearance and hardness of metal,but are also easy to be weld and can sometimes be used as a substitute for metal products.Due to the low surface activity of inactive substrate materials(e.g.,plastics,glass,ceramics,etc.),there is a significant difference between their properties and those of metals,so surface metallization cannot be achieved by physical deposition and adsorption alone.The preparation of PA12 composite powders with metal particles was realized by constructing activation sites in situ on the surface of nylon12(PA12)powder,adsorbing catalyst particles and catalytic chemical plating,which elucidated the mechanism of adsorption of catalytic sites and catalytic chemical plating on the surface of PA12 powder.
