▎ 摘　　要

NOVELTY - A tetra-beta-carboxyphenoxy-metal phthalocyanine/graphene composite material comprises 0.85-1.69 wt.% tetra-beta-carboxyphenoxy metal phthalocyanine, 0.40-0.56 wt.% graphene, 80.1-83.1 wt.% N,N-dimethylformamide, 2.61-3.05 wt.% ammonia water solution and 15.2-17.1 wt.% ammonia water. USE - Tetra-beta-carboxyphenoxy-metal phthalocyanine/graphene composite material for gas sensitive material. ADVANTAGE - The composite material has graphene of easy agglomeration and relatively inert surface, and improves selectivity, recovery capability and sensitivity of the sensitive material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing tetra-beta-carboxyphenoxy-metal phthalocyanine/graphene composite material.
