Abstract: In this report, a novel thermosensitive poly(N-isopropylacrylamide-co-maleic anhydride-beta-cyclodextrin)/(TiO2-multi-walled carbon nanotubes) (poly(NIPAM-co-MAH-beta-CD)/(TiO2-MWCNTs)) composite was synthesized by UV light photoinitiating method. The results indicated that MAH modified beta-CD (MAH-beta-CD) could polymerize to NIPAM by UV light irradiation in the presence of TiO2-MWCNTs composite nanoparticles. The characteristic results confirmed that the TiO2-MWCNTs composite nanoparticles were embedded evenly within the thermally responsive copolymer of NIPAM and MAH-beta-CD. The effects of irradiation time and TiO2-MWCNTs concentration on the yield of the composites were investigated by keeping NIPAM to MAH-beta-CD mass ratio constant. The optimal polymerization reaction conditions were a TiO2-MWCNTs concentration of 10 wt.% under UV light for the illumination of 3 h. (C) 2012 Wen Feng Jiang.
