摘要
In this report, a novel thermosensitive poly（N-isopropylacrylamide-co-maleic anhydride-β-cyclodextrin）/（TiO2-multi-wal,led carbon nanotubes） （poly（NIPAM-co-MAH-β-CD）/（TiO2-MWCNTs）） composite was synthesized by UV light photoinitiating method. The results indicated that MAH modifiedβ-CD （MAH-β-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-β-CD. The effects of irradiation time and TiO2-MWCNTs concentration on the yield of the composites were investigated by keeping NIPAM to MAH-β- 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.
