Solvent/temperature dual-responsive photonic crystal structural-color films through double inverse opal structure†
Abstract
A solvent/temperature dual-responsive P(NIPAM-AM) hydrogel is proposed. The free energy model of the hydrogel microstructure and the transformation of the properties of the hydrogel chain segment during deformation were further analyzed. The resultant structural-color hydrogel film was applied to on-demand patterning.
