After adding 4 parts of 10% AgNO3 aqueous solution to 1 (4) parts of this emulsion, it was cast onto a polyester film,
A uniform film was obtained by drying at 145°C for 3 minutes. The obtained film is simply a blend of antibacterial agents, and as stated in the text, the results of testing the durability of antibacterial activity on this film showed that the antibacterial activity disappears relatively easily by washing with water. I found out.
