Abstract

The invention relates to a method for utilizing an ink-jet printing technology to simply and quickly prepare a photonic crystal composite membrane with ultrafast responsiveness and patterning. The method for utilizing the ink-jet printing technology to prepare the photonic crystal composite membrane with responsiveness and patterning utilizes mixed liquor of monodisperse emusion particles, a monomer of a responsiveness function polymer, a cross-linking agent, an initiator, a high boiling point addictive and water as ink, the ink-jet printing technology is used for acquiring the photonic crystal composite membrane which is a patterning composed of microdroplet units, and the photonic crystal composite membrane is in response to humidity, to temperature, to acid gas, and / or to alkaline gas. The microdroplet units are piled up by frameworks of the monodisperse emulsion particles, and a responsiveness cross-linking polymer acquired by the monomer of the responsiveness function polymer through cross-linking polymerization is filled in gaps of the frameworks of the monodisperse emulsion particles. The photonic crystal composite membrane can not only achieve visual detection by distinguishing color change through naked eyes of people, but also have wide application prospect in quick intelligent display unit caused by external environment change, dangerous substance detection, chemical reaction monitoring, photoswitch, integrated optical circuit, and the like.

Description
