▎ 摘 要
NOVELTY - Conductive MOF modified gas-sensing material comprises conductive metal organic framework material of graphene assembly material and its surface modification. The graphene assembly material has a two-dimensional layered structure and obtained by assembling a polycationic electrolyte and negatively charged graphene oxide. The conductive MOF-modified gas-sensing material can be used to reduce the influence of humidity in the gas detection process. USE - Conductive MOF modified gas-sensing material used in gas detection (claimed), where the gas detection is detection and identification of different organic/inorganic gases and human exhaled breath. ADVANTAGE - The conductive MOF modified gas-sensing material has good gas response stability of 0-98% wide range humidity, and realizes trace organic at room temperature. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a gas sensor chip, which involves: a. preparing the self-assembled suspension of the conductive MOF modified gas-sensing material; and b. confining the ITO-PET interdigital electrode with PDMS film; treating the electrode with oxygen plasma, then taking the self-assembled suspension of the conductive MOF modified gas-sensing material prepared it into the electric confinement domain, drying at room temperature, placing dried electrode in a reducing vapor atmosphere for reduction to obtain product.
