Graft polymer, conductive hybrids

J. Li, L. Zhu, Y. Wu, Y. Harrma, A. Zhang, H. Tang, Hybrid composites of conductive polyaniline and nanocrystalline titanium oxide prepared via selfassembling and graft polymerization . Polymer, 47, 7361-7367, (2006). 

In this section, some peculiarities of copolymerization conducted in CRP systems will initially be discussed and then examples of various types of copolymers will be provided. They will include statistical, gradient, and alternating copolymers, as well as block and graft copolymers. Some special systems will be also presented and they will include preparation of stereoblock copolymers, and various hybrid materials formed by either mechanistic transformation or by growing well-defined polymers from flat, colloidal, or irregular surfaces. 

The grafting-from approach (separate covalently linked nanocrsytal/polymer layers) was carried out by surface modification of the hydroxylated CdS suspension with metha-cryloxypropyltrimethoxysilane (MPS) to which an in situ CCTP of MMA was conducted, forming covalently linked CdS-PMMA hybrids (Figure 6).
