Abstract

Poly(hydroethyl acrylate) (PHEA) was grafted from ZnO nanoparticles via the copper-mediated surface-initiated atom transfer radical polymerization (SI-ATRP) technique with the bromo-acetamide modified ZnO nanoparticles (BrA-ZnO) as macroinitiators with the catalysts of 1,10-phenanthroline and Cu(I)Br in water. Graft reaction was first order kinetic with respect to the polymerizing time in the low monomer conversion stage, this being typical for ATRP. A percentage of grafting (PG%) of 62.4% was achieved in 12 h, calculated from the elemental analysis results. The product, poly(hydroethyl acrylate) grafted ZnO nanoparticles (PHEA-ZnO) were also characterized with Fourier transform infrared spectroscopy (FT-IR), UV–vis spectroscopy, thermogravimetric analysis (TGA), X-ray photoelectron spectroscopy (XPS) and transmission electron microscopy (TEM).
