In this report,a novel thermosensitive poly(N-isopropylacrylamide-comaleic anhydride-p-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 modifiedβ-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.
In this report, a novel thermosensitive poly (N-isopropylacrylamide-comaleic anhydride-p-cyclodextrin) / (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. 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.
