Light-responsive Hydrogel for Motion Sensor Application |
| 초록 |
Light-responsive film-hydrogel with excellent mechanical properties and electronic response changes during stretching and relaxing has been successfully fabricated. The mechanical properties of the hydrogel are provided by intermolecular interaction between Poly(Vinyl Alcohol) and Chitosan while the electronic properties are provided by polymer dots (CD). The film-hydrogel demonstrates hydrophobic-hydrophilic transition during UV-vis light irradiation which enables the hydrogel to undergo dimensional change. The effect of water treatment further changes the hydrogel mechanical features changing from fragile film to elastic hydrogel (278 % strain). Moreover, finger movement shows different electronic signal during bending and releasing suggesting the capability of the film-hydrogel as the motion sensor. This work was supported by Korea National University of Transportation in 2019. |
