▎ 摘　　要

NOVELTY - The element has a room temperature graphene oxide/phthalocyanine composite material element unit provided with an interdigital electrode and made of graphene oxide/phthalocyanine composite material. The graphene oxide/phthalocyanine composite material is amino metal phthalocyanine. The amino metal phthalocyanine is made of oxygen, amine, iodine, alkyl base or alkoxy and copper. USE - Room temperature graphene oxide/phthalocyanine composite material element. ADVANTAGE - The element has high room temperature, high reversibility, high selectivity, high stability, better resistance effect and high sensitivity, and increases ammonia gas concentration at 12.5 ppm-3200 ppm concentration range and avoids oxidized defects. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a room temperature graphene oxide/phthalocyanine composite material element preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical view illustrating a room temperature graphene oxide/phthalocyanine composite material element preparation method.'(Drawing includes non-English language text)'
