Preparation and characterization of layer-by-layer self-assembled polyelectro…

Abstract. SiO2 nanoparticles capped with γ -aminopropyltrimethoxysilane were doped into polyelectrolyte (poly- (allylamine hydrochloride), PAH, and poly(acrylic acid), PAA) multilayer films via spin-assisted layer-bylayer self-assembly. The resulting as-prepared multilayer films were heated at a proper temperature to generate cross-linked composite films with increased adhesion to substrate…
