Synthesis, Characterization of Polyacrylate-g-Carbon Black and Its Application to Soap-Free Waterborne Coating

摘要

Polyacrylate-g-Carbon Black (abbrev, as gCB) was prepared by free radical polymrizationof acrylate monomers onthe carbonblack surface, which was initiated by a redox system consisting of cerium ammonium nitrate and hydroxymethyl carbon balck. gCB was ascertained by X-ray Photoelectron Spectrometry (XPS). The optimum conditions of synthesis were studied. The stabilities of gCB dispersing inwater were studied by zeta potential measurement and spectrophotometric analysis. The results could be dispersed inthe soap-free hydrosol forming a colored soap-free water-borne coating with satisfactory comprehensive performance.
