Abstract
Two kinds of poly quaternary ammonium salts (PQAS) namely PDMC (poly (methacryloxyethyl trimethyl ammonium chloride)), CPAM (methacryloxyethyl trimethyl ammonium chloride / acrylamide copolymer) were prepared. The chemical structures of the PQAS were characterized by Fourier transform infrared (FT-IR), nuclear magnetic resonance (1 H NMR) spectrum, thermogravimetric analysis (TGA), and scanning electron microscope (SEM). The antibacterial activity of PQAS against three kinds of bacteria and one kind of fungus, was evaluated by the method described in QB/T 2738-2012. Antibacterial tests showed that the antibacterial activity increased with the increase of cationicity and molecular weight on PQAS. It shows the antimicrobial activity for different bacteria strain follow this order: Escherichia coli (E. coli) > Staphylococcus aureus (S. A.) > Shigella > Monilia albican (M. A.).
