| titleOfInvention | Photoresponsive polymer microsphere system and preparation method thereof |
| abstract | The invention discloses a photoresponsive polymer microsphere system and a preparation method thereof. The system is a solution containing cyclodextrin, an azo compound having cis-trans isomerism respectively under the irradiation of ultraviolet light and visible light, and amphiphilic polyelectrolyte containing a hydrophobic alkyl chain. Polymer microspheres are generated when the system is under the irradiation of visible light, and the polymer microspheres in the system are decomposed under the irradiation of ultraviolet light. The preparation method comprises the following steps of: dissolving the amphiphilic polyelectrolyte in a solvent; completely stirring a microsphere solution; and then adding cyclodextrin and stirring for dissolving cyclodextrin; and finally adding the azo compound to obtain the photoresponsive polymer microsphere system after the azo compound is dissolved. The photoresponsive polymer microsphere system provided by the invention has the characteristics that the preparation conditions are moderate, the formation and decomposition of microspheres are reversible, quick and controllable. The photoresponsive polymer microsphere system has a bright application prospect in the biomedicine field such as medicine transfer, medicine slow release and the like, as well the anti-counterfeiting filed relating to trademarks, bills, even military industry, national defense and the like. |
