Description

technical field

[0001] The invention belongs to the field of antibacterial agents and preparation thereof, in particular to a benzophenone bisamide bridged bisquaternary ammonium salt type light-induced synergistic antibacterial agent and a preparation method thereof. Background technique

[0002] People will inevitably come into contact with various microorganisms in daily life. Because the surface of textiles, household items and other materials has a certain roughness and more microporous structure, bacteria can easily breed and transfer to the surface of the skin, which is harmful to the human body. serious health hazard. Therefore, in recent years, research on antibacterial agents and antibacterial materials has received extensive attention. Antibacterial agents are mainly divided into inorganic nano-antibacterial agents, organic antibacterial agents and natural antibacterial agents. Inorganic nanomaterials have a small size effect and excellent photochemical activity...
