Abstract Electroless nickel plating provides a rapid and low-cost approach to prepare surface-metallization material, but complicated technology would increase cost and restrict its application. In this work, a new kind of Pd nanoparticle/polymer brush (Pd/PB) catalytic solution (AS) with a mixture of deionized water, ethanol, 3-aminopropyltriethoxysilane (KH550), PdCl2 solution was designed to modify and activate polyethylene terephthalate (PET) simultaneously. Pd nanoparticle could be adsorbed by PB with –NH2, Si–O–Si groups from hydrolyzed KH550. An activated layer with Pd/PB structure established on PET surface after coating AS solution. The generated Ag/PB that served as seed to catalyze the electroless nickel plating. As a result, a facile route for electroless nickel plating was achieved. The maximum effective thickness, rupture work and adhesion of Ni-plated coating were about 0.8 μm, 0.4 J/m2, and 5B, respectively, and it maintained considerable conductivity even after 1000 times of cyclical bending. This dependable technology has great potential application in the preparation of metal-polymer material.

PET 片材表面金属化：制备 Pd 纳米颗粒/聚合物刷以催化化学镀镍

摘要 化学镀镍为制备表面金属化材料提供了一种快速、低成本的方法，但复杂的工艺会增加成本并限制其应用。在这项工作中，设计了一种由去离子水、乙醇、3-氨基丙基三乙氧基硅烷 (KH550)、PdCl2 溶液混合而成的新型 Pd 纳米颗粒/聚合物刷 (Pd/PB) 催化溶液 (AS)，用于改性和活化聚对苯二甲酸乙二醇酯。 PET) 同时。Pd 纳米颗粒可以被 PB 吸附，其中含有来自水解 KH550 的 -NH2、Si-O-Si 基团。涂覆 AS 溶液后在 PET 表面建立的具有 Pd/PB 结构的活化层。生成的 Ag/PB 作为种子催化化学镀镍。结果，实现了化学镀镍的简便途径。最大有效厚度，镀镍涂层的断裂功和附着力分别约为 0.8 μm、0.4 J/m2 和 5B，并且即使在 1000 次循环弯曲后仍保持相当的导电性。这种可靠的技术在金属聚合物材料的制备中具有巨大的应用潜力。
