| 논문초록 | Interest in soft actuators has surged due to their precision and remote controllability, yet their predominantly unidirectional action limits broader application. Previously, donor acceptor Stenhouse adducts (DASA), negatively photochromic molecular photoswitch, has shown its potent for tunable photothermal actuation depending on its absorbance value. Based on our hypothesis that that variable 2D DASA-polymer absorbance patterns can direct bending in multiple directions by altering local modulus and photothermal efficiency, we introduce a multi-directional soft actuator by harnessing 2D absorbance patterns of DASA-polymer actuator. We present a synthetic pathway to chemically conjugate DASA in crosslinked polymer matrix, polyethyleneimine-bisphenol A diglycidyl ether, by detouring its low thermal and chemical stability. Our results highlight the benefits of rewritable absorbance patterns and visible light absorption of DASAs for creating versatile, multi-directional soft actuator. |
