Abstract

A self-templated approach has been developed for the synthesis of TiO ₂ microcapsules with tunable size and wall thickness by heating sol-gel derived TiO ₂ microspheres with poly(acrylic acid) (PAA) in a diethylene glycol (DEG) solution. PAA plays a crucial role in the formation of microcapsules by crosslinking the surface TiO ₂ nanoparticles and preventing them from dissolution by DEG. Hollow microcapsules form when DEG molecules penetrate the outer layer and remove the core materials by forming soluble titanium glycolate.
