A novel processing scheme for core-shell nano composites using controlled polymer adsorption

A new processing scheme has been developed for the preparation of core-shel l structured composite particles that can be used as building blocks for th e fabrication of nanocomposites [1]. The scheme is a two stage coating proc ess utilizing controlled polymer adsorption and bridging in which a layer o f nano sized particles is bridged onto submicron sized core particles. The coating process is monitored using electrokinetic techniques as well as SEM . The controlled coating process was used also to prepare multilayer nanoco mposites. The application of the coating process to concentrated suspension s (15 volume percent) required in ceramic processing was shown to be feasib le, Ceramic compacts were successfully prepared using pressure filtration m ethods and tested for their green density and flexibility.
