Abstract
Abstract In this report, a novel thermosensitive poly( N -isopropylacrylamide- co -maleic anhydride-β-cyclodextrin)/(TiO 2 -multi-walled carbon nanotubes) (poly(NIPAM- co -MAH-β-CD)/(TiO 2 -MWCNTs)) composite was synthesized by UV light photoinitiating method. The results indicated that MAH modified β-CD (MAH-β-CD) could polymerize to NIPAM by UV light irradiation in the presence of TiO 2 -MWCNTs composite nanoparticles. The characteristic results confirmed that the TiO 2 -MWCNTs composite nanoparticles were embedded evenly within the thermally responsive copolymer of NIPAM and MAH-β-CD. The effects of irradiation time and TiO 2 -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 TiO 2 -MWCNTs concentration of 10 wt.% under UV light for the illumination of 3 h.
