Non-conductive electroplating substrate prepn. - by forming dispersion contg. carbon black on surfaced and separating to disperse carbon black before electroplating

摘要

Process for electroplating a conductive metal to a non-cnctiv non-conductive material comprises: a) preparing a liq. dispersion of carbon black; b) applying the dispersant to the non-conducting material surface; c) sepg. all of the dispersant from the carbon black thus depositing a continuous layer onto the non-conductive surface; and d) electroplating a continuous conducting metal layer upon the carbon black/non conductive layer. - The liq. dispersion of carbon black consists of: i) carbon black particles with an av. dia. of up to 30 um in the dispersion; ii) an effective dispersing amt. of surfactant; and iii) liq. dispersing medium.
