There is a chemical hydrophobic main chain and hydrophilic side chain of poly (N-isopropyl acrylamide)(PNIPAM). The molecular chain conformation of PNIPAM is sensitive to temperature due to its special
chemical structure that responses reversibly with temperature about physical conformation. Polyhedral oligomeric silsesquioxanes (POSS) is a cubic silica core surrounded by eight corner functional group which can be incorporated into polymer material. PNIPAM was prepared by atom transfer radical polymerization (ATRP) carried out at 0 oC and resulted
the narrow polydisperity of homopolymer. We produced star-like organic/inorganic hybrid POSS-PNIPAM via click and hydrosilylation reactions.
The synthesis of POSS-PNIPAM copolymers was characterized by GPC, 1H NMR and FTIR analyses. DLS, UV-Vis and PL spectrometer were use to measure the particle size, cloud point and photoluminescence of PNIPAM solution in this study.
