Stimuli-responsive polymers are high-value materials that have been applied in many places. There are many kinds of stimuli-responsive polymer. Physical (light, temperature, magnetic), chemical (solvent, ionic strength, pH), or biological stimuli (enzymes, receptors). In the present work, spironaphthoxazine (SPO) methacryloyl was used as a light-stimuli monomer, which undergoes photo-isomerization from closed to open forms resulting the changes in color and hydrophobicity under the UV light of 365 nm. N-isopropylacrylamide (NIPAAm) was used as temperature responsive material. SPO moiety were prepared from N-isopropylacrylamide (NIPAAm) and styrene monomers through reversible-addition fragmentation chain transfer (RAFT) polymerization, and corresponding vesicles were also prepared using W/O/W double emulsion. Photo and temperature responsive behaviour of these vesicles are discussed. |
