Abstract. A class of acrylic copolymers with narrow molecular weight distribution from butyl methacrylate and glycidyl methacrylate comonomers via atom transfer radical polymerization was synthesized. Various types of polarities including hydroxyl-amines, glycols, and carboxylic acids were then grafted onto the oxirane side groups. The resultant comb-like copolymers with different polar pen…
Abstract. Highly hydroxylated barium titanate (BaTiO3) nanoparticles have been prepared via an easy and gentle approach which oxidizes BaTiO3 nanoparticles using an aqueous solution of hydrogen peroxide (H2O2). The hydroxylated BaTiO3 surface reacts with sodium oleate (SOA) to form oleophilic layers that greatly enhance the dispersion of BaTiO3 nanoparticles in organic solvents such as tetr…
