| 제목 | Direct Ink Writing of Chiral Nematic Liquid Crystal Elastomers: Mechanochromic and Angle-Dependent Structural Color |
| 초록 | Here,we present a new processing method to prepare chiral nematic liquid crystal elastomer(CLCE) via UV-assisted direct ink writing (DIW). Interestingly, the helicalaxis of the DIW-processed CLCE film is slanted by about 40˚ along the printing direction,which resulted in either blue- or red-shifting of the reflected structuralcolor of the CLCE film depending on the printing direction and the viewingangle. In addition, complex mechanochromic properties of the CLCE were further demonstratedthat can be manipulated by the printing direction as well as the degree ofstretching. The combination of chirooptical and mechanochromic properties ofCLCE along with 3D printing method will pave the way to develop an interestingclass of anti-counterfeiting materials and strain sensors. |
