▎ 摘　　要

NOVELTY - MXene-graphene oxide composite film with humidity response comprises MXene sheets and graphene oxide sheets located on both sides of the MXene sheets, and the MXene sheets are titanium carbide (Ti3C2OX). The composite film has layer-by-layer structure, and each layer is a sandwich structure. USE - The composite film is useful in fields of water purification, intelligent drive, electricity, and respiratory monitoring in medical and health field (claimed). ADVANTAGE - The composite film has good stability, good hydrophilicity, humidity sensitivity, conductivity and antibacterial property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the MXene-graphene oxide composite film with humidity response.
