▎ 摘  要

NOVELTY - Preparation of photonic crystal volatile organic compounds (VOCs) sensor comprises: adding methyl cellulose, polyvinyl alcohol and graphene oxide into water to prepare mixed solution; filling the mixed solution into a photonic crystal array template and drying; then removing the photonic crystal film by the photonic crystal array template; and then coating the photonic crystal film with cellulose acetate solution to obtain the photonic crystal VOCs sensor. USE - The method is useful for preparing photonic crystal VOCs sensor, and removing the photonic crystal array template is soaking in toluene (claimed). ADVANTAGE - The VOCs sensor: has high biological compatibility and good flexibility; is simple and convenient to use; has obvious response to multiple VOCs, especially has high selectivity response to the acetone; and can realize the detection of multiple VOCs. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for photonic crystal VOCs sensor prepared by the above-mentioned method.
