▎ 摘　　要

NOVELTY - A membrane comprises substrate and layer of sensitive material, where layer of sensitive material comprises hexafluoroisopropanol modified poly(methyl hydrogen siloxane) and hexafluoroisopropanol modified graphene oxide in a mass ratio of 1:0.5-1. USE - Membrane for use in device for sensing 2-acetyl-1-pyrroline and detecting aroma quality of rice (all claimed). ADVANTAGE - The membrane has thickness of 80-200 nm and detects concentration of 2-acetyl-1-pyrroline in a rapid and simple manner. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a method for preparing the membrane (2) a device for sensing 2-acetyl-1-pyrroline.
