Abstract

original image

A facile approach to ultrafine hydrophilic polymeric nanoparticles within 10 nm is developed by anhydrous or aqueous inverse microemulsion polymerization of N,N-dimethylacrylamide. Since auto- precipitation of products occurs without any demulsifiers, the recycling of surfactants is feasible. The auto-precipitation mechanism is proposed and discussed. Functionalization of the nanoparticles is achieved by employing them as nanoreactors to form hybrids with titanium tetraisopropoxide.
