Abstract Organic–inorganic composite antibacterial materials based on AgPc/Ag and aminosilane‐modified silicate (Ormosil) were prepared by sol‐gel processes an in situ reduction method. The physical chemical properties of AgPc, Pc‐Ormosil AgPc‐Ormosil/Ag composites analyzed SEM, XRD, NMR XPS spectroscopy. As a result, Ag nanoparticles bonded chelated matrix. morphology analysis SEM showed that the AgNPs matrix spherical uniformly distributed, with size about 5–10 nm. These results indicated coordinated Pc (N−Ag−N) Ormosil (−CH 2 NH…Ag) to form composite. effects Gram‐negative Pseudomonas aeruginosa Escherichia coli , Gram‐positive Staphylococcus aureus Bacillus subtilis evaluated inhibiting ring, minimum inhibitory concentration (MIC), bactericidal (MBC) plate counting.
