The antibacterial protective film comprises an endogenous antibacterial protective film and an exogenous antibacterial protective film, wherein the endogenous antibacterial protective film is mutually bonded and is in contact with a wound, and the exogenous antibacterial protective film is incontact with the external environment. The endogenous antibacterial protective film is a pH-sensitive degradable high-molecular polymer film loaded with an antibacterial agent, and the pH-sensitive degradable high-molecular polymer comprises acid-sensitive chemical bonds. When inflammation is generated in the wound due to endogenous bacterial infection, the pH value of the wound is reduced, so that the acid-sensitive chemical bonds are broken, and the loaded antibacterial agent is slowly released to inhibit the endogenous bacterial infection. The exogenous antibacterial protective film is a chitosan film grafted with graphene and is used for blocking and inhibiting exogenous bacterial infection. The graphene is connected with the chitosan through chemical bonds and thus cannot enter a human body, so that exogenous bacteria can be effectively inhibited.
