The cinnamoyl cellulose nanofiber (Cin-CNF ) was synthesized through the reaction between Cinnamoyl chloride and CNF. The Cin-CNF/Alginate beads were prepared using dropping method in which the solution of Cin-CNF/alginate was added into calcium ion solution. The electrostatic attraction within alginate and calcium ion dominated the formation of beads. When the beads were put under UV irradiation(365nm) individually, the cinnamoyl group of Cin-CNF will be dimerized. So the photo dimerization reaction will give the UV-responsive ability to the beads. In the present study, we prepared 4 kinds of beads. The beads were put under UV irradiation(254nm) for 0/5min to be de-dimerized for releasing the FITC-Dextran. When the ratio is 1:3 and the UV irradiation(365nm) was 60min, the beads shows more significant change in release. Finally, a UV Irradiation-responsive reaction was obtained. |
