The color of bamboo itself mainly comes from the chromophores in lignin, tannin and other resinous compounds, while bamboo can achieve the bleaching effect by delignification. Inspired by chromophore coloration strategies, this study employed a thermosetting epoxy resin Ag-80/DDM with responsive diarylmethane chromophores, which was impregnated into delignified bamboo via vacuum impregnation. This resulted in the creation of an intelligent transparent bamboo with intrinsic photo- and pH-responsiveness. The diarylmethane chromophores in the ther...
