Résumé : |
A series of antibacterial styrene-acrylic emulsions (SA-Mn, n = 5, 10, 15, 20) with different contents of 5-(methacryloxy-2-ethoxyaminocarbonyl)methyl-thiazole (MEMT) were successfully synthesized, and SA-M20 was used to prepare a water-based antibacterial coating (PSA-M20). The structures of the films (SA-Mn-F) obtained from SA-Mn were analyzed by Fourier-transform infrared spectrometry using the attenuated total reflectance model (FTIR-ATR). The effects of the MEMT content on the properties of the emulsions and related films were investigated in the aspects of particle size, thermal stability, pencil hardness, adhesive force grade, water resistance, and surface morphology. The results showed that all the emulsions or related films had acceptable properties. The antibacterial and antibacterial durability tests showed that films obtained from emulsions SA-M15, SA-M20, and the coating PSA-M20 had strong and durable antibacterial activity against E. coli and S. aureus. |
