Study on the Antibacterial Performance of Silver Antibacterial Agents in Polypropylene Random Copolymer(PP-R)
The silver-based antibacterial agent was mixed into the PP-R material in a certain proportion,and its antibacterial effect on Staphylococcus aureus and Escherichia coli was tested.By comparing the effects of different suppliers,granulating process and appending proportion of silver antibacterial agent on PP-R materials,it is determined that the best addition ratio is 5％for one-time granulation.And the antibacterial performance of the sample remains unchanged after different heat treatments,showing the excellent thermal stability of the silver-based antibacterial material.
