▎ 摘　　要

NOVELTY - The material has a functionalized graphene microspheres and polyaniline that are coated on the functionalized graphene microspheres. The functionalized graphene microspheres are reduced graphene microspheres modified by sodium polystyrene sulfonate. The polyaniline is formed by adsorbing aniline monomer onto the functionalized graphene microspheres and performing chemical oxidative polymerization on the functionalized graphene microspheres. The size of the gas-sensitive material for ammonia gas detection is preset value. USE - Gas-sensitive material for detecting ammonia gas for gas-sensing electrode of sensor (claimed). ADVANTAGE - The material is quickly respond and revert the low-concentration ammonia gas at room temperature and high reaction sensitivity and low detection limit are ensured. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the method for preparing a gas-sensitive material for ammonia gas detection. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating the gas-sensitive material for detecting ammonia gas. (Drawing includes non-English language text)
