Molecularly Engineered Photomotility of Untethered Monolithic Soft Robots |
| 초록 |
Azobenzene-functionalized liquid crystal polymer networks are promising materials for light-fueled untethered soft robots where molecular machines are embedded into polymeric networks. In this work, we varied the spacer length of the azobenzene-derived molecular machines ranging from 2-8 towards the systematic investigation of structure-property relationships for photomotility of polymers. Photoactive molecular machines are self-assembled along with liquid crystal monomers with twisted nematic boundary conditions followed by photopolymerization. The light-induced deformation and locomotion of the soft robot were performed by irradiation of broadband UV light. In this presentation, we examine the phase behavior of the azobenzene-based molecular machines and their mixture with liquid crystal monomers. Finally, we discuss various parameters affecting the photomotility of the untethered monolithic soft robots. |
