In this work, acrylate copolymer has been fabricated by graft copolymerization of acrylate monomer (EMA:EA is 70:30) with functional TiO2 nanoparticles, which was surface-modified by the silane coupling agent methacryloxy propyl trimethoxyl silane (KH570) to attach active ends. The structure and properties of the copolymer were characterized by FT-IR, FE-SEM, differential scanning calorimetry, thermogravimetric analysis, ultraviolet-visible spectra, and discoloration. Characterization revealed that functional TiO2 particles were grafted onto the chain of the acrylate copolymer and the acrylate copolymer showed excellent photo-oxidative stability and transparency. The acrylate copolymer was applied to protect and consolidate ancient ivory by surface coating without destruction of chemical structure. © 2016 Wiley Periodicals, Inc. Source
