Surface characterizations of functionalized surfaces. (A) FT-IR transmission spectra of the polymer films employed to functionalize the surface of the TiO2 nanoparticles. The spectra are arranged in order (top to bottom): poly(allylamine); poly(vinylacetic acid); poly(diethyleneglycol vinyl ether (B) High resolution C(1s) XPS spectrum of a pulsed plasma polymerized polyvinylacetic acid film deposited on TiO2 nanoparticles, using a plasma on/off ratio of 0.75/20 ms.
