| Abstract: | A thermo-responsive anisotropic photonic hydrogel: poly(dodecyl glyceryl itaconate)/polyacrylamide-poly(N-isopropylacrylamide) hydrogel (PDGI/PAAm-PNIPAM hydrogel) has been reported. Hydrogels with uniaxially aligned lamellar bilayers possess bright structural color and swelling anisotropy, while PNIPAM-based hydrogels exhibit distinct thermo-responsive properties around a lower critical solution temperature (LCST). Hybridization of thermo-responsive PNIPAM with the lamellarhydrogel can give the anisotropic photonic hydrogel with various fascinating thermo-responsive properties, such as structural color/turbid transition, thermo-responsive structural color, and anisotropic deswelling/reswelling behavior by temperature stimuli. The temperature-induced change in turbidity, structural color, and anisotropic swelling of the gel around LCST can be tuned by controlling the incorporated PNIPAM density. PNIPAM can be regioselectively incorporated into the specific region of the lamellar hydrogels by photomasking during UV polymerization. The PDGI/PAAm-PNIPAM hydrogel can find diverse promising applications, such as smart windows and smart displays. |
