Description
Technical Field
The invention relates to the field of antibacterial coatings, in particular to a preparation method of an antifogging antibacterial coating made of a nano composite material.
Background
Because the medical care personnel are in contact with the patient in the viral environment for a long time, the medical care personnel are exposed to the viral environment carelessly and directly, and the medical care personnel can be infected by pathogens in the process of demisting the eye cover of the protective clothing, or the eye cover of the protective clothing is not disinfected completely, and the like. At this moment, an ray of medical personnel just need a coating that antifog effect is showing, has good antibiotic anti-virus effect urgently, avoids medical personnel the inconvenience that brings at the during operation eye-shade fog, eliminates breeding of eye-shade surface bacterium, and guarantee medical personnel can be under clear field of vision, and the novel coronavirus pneumonia patient of effectual treatment also ensures medical personnel's self safety simultaneously.
Based on the development of antifog surface research, there are generally three antifog surface treatment strategies that can prevent the surface of the face shield from forming refracted water droplets or uneven water layers: (1) super-hydrophilic antifogging: the surface energy of the protective mask is increased, and the water drops are quickly flattened by larger surface tension to form a uniform water layer, namely a super-hydrophilic surface; (2) super-hydrophobic antifogging: the surface energy of the protective mask is reduced, and water drops roll off from the surface of the substrate by smaller surface tension, namely a super-hydrophobic surface; (3) water absorption antifogging: the amphiphilic wettable surface is configured to allow water droplets to be absorbed into the interior of the coating, i.e., the amphiphilic water-absorbing surface. The protective mask antifogging coating prepared by the traditional method has the defects of poor scratch resistance and poor long-term antifogging property. In addition, the single function of the antifogging coating limits the application range of the antifogging coating, such as coatings required by medical instruments such as gastroscopes, throats, protective clothing eyeshields and the like, and the antifogging coating has excellent antifogging effect and good antibacterial performance, so that the medical detection instrument or the protective device is clear, fogless, sanitary and aseptic in the application process.
Antibacterial strategies include both bactericidal and antibacterial adhesion, and the process of bacterial killing involves physical or chemical damage that occurs on or within the surface of the bacteria. Researchers at home and abroad make researches on various antibacterial mechanisms of nano materials, and can classify the nano materials into the following categories: (1) the structure is antibacterial: bacterial membranes are important targets of many antibacterial preparations, and due to the unique physical properties of the nano materials, such as surface topology, size, geometry, surface charge and the like, the direct contact between bacteria and the nano materials can also damage bacterial cell membranes. The antibacterial mechanism of the nano material is physical damage to the bacterial cell membrane, and is not related to the type of bacteria. Therefore, the antibacterial nano structure has good universality. (2) Chemical antibiosis: the nano material does not directly contact with microorganisms to cause mechanical rupture of cell membranes, but induces peroxidation of bacterial cell membrane lipids by generating toxic components such as Reactive Oxygen Species (ROS) or Reactive Nitrogen Species (RNS) to damage intracellular proteins or genes, thereby achieving the effect of sterilization. The nano material can actively attack bacteria through nano particles or passively cause bacterial damage under illumination, and can be used as a catalyst to convert molecules in a biological environment into toxic components so as to promote the killing of bacteria.
The single sterilization coating can effectively kill bacteria, but cannot eliminate the problem that bacterial fragments are remained on the transparent substrate, but can effectively meet the antifogging and antibacterial effects required by optical instruments such as gastroscopes, throats, eye shields of protective clothing, goggles and the like by a sterilization-anti-adhesion combination method. Wherein the quaternary ammonium salt and the nano TiO2The novel antibacterial material prepared by photocatalytic coupling integrates the sterilization and anti-adhesion performances, and has the characteristics of wide antibacterial spectrum, safety and convenience in use, energy conservation, environmental friendliness and the like. The cell membrane of microorganism is usually composed of negatively charged lipid layer and peptidoglycan, the quaternary ammonium salt molecule has positive charge, after high molecular weight, the relative molecular weight is increased, the charge density is increased, the negatively charged bacteria on the cell surface can be easily adsorbed to the surface, and then the cell membrane is combined to break the cell, the intracellular materialSubstances such as RNA, DNA and K + leak out, resulting in bacterial death. Nano TiO in coating2Has the advantages of durability, broad spectrum, heat resistance, difficult generation of drug resistance, thorough sterilization and the like, is nontoxic and tasteless, has no stimulation to skin, and has high safety. Under the condition of ultraviolet irradiation, nano TiO with anatase crystalline phase2Not only can generate ROS to sterilize, but also can effectively decompose and remove bacterial remains and various organic substances contained in the bacterial remains. While the antifogging is achieved by structuring the superhydrophilic surface, the hydration layer formed on the coating surface also prevents the adhesion of bacteria.
For this reason, how to improve the adhesion of the coating to the substrate and the mechanical strength of the coating is the development direction of the industry today.
