    摘要:

    ABS塑料直接電鍍過程省略了化學(xué)鍍,是塑料電鍍史上的重大突破。只有制備出高分散性、粒度小的膠體催化劑,才可以成功實施直接電鍍。采用液相還原法制備了幾種不同分散性的催化劑,并采用紫外.可見吸收光譜(UV-VIS)、納米粒度分析儀和立體顯微鏡來表征不同分散性的膠體鈀溶液。分散性好的膠體鈀溶液的紫外.可見吸收峰變寬,經(jīng)過活化可以進(jìn)行直接電鍍。香草醛加入到膠體鈀溶液中可以提高分散性和減小膠體粒度。

    Abstract:

    It is well known that direct copper plating on ABS plastics has found widely industrial application for eliminating plating. The Pd/Sn colloids for direct copper plating have better dispersivity and smaller size than the colloids for electroless electroless Ultraviolet-visible absorption spectrometry, nanophox, and stereoscopic microscopy were used to characterize the colloids. The good dispersivity colloids have excellent catalysis for direct copper plating and its UV-VIS peaks are broadened. In order to enhance the dispersivity and minimize the particle size, vanillin was added to colloids solution in the present investigation.
