Abstract: Taking chitosan (CTS) as substrate and Ag/Cu as inorganic antibacterial agents,Ag/Cu-CTS composite antibacterial particles are prepared,and hence a natural,non-polluting antibacterial material for washing machine is prepared.The preparation conditions and performance of Ag/Cu-CTS composite antibacterial particles are studied.The effects of Ag concentration,porogen dosage,crosslinking agent concentration,and crosslinking temperature on the performance of antibacterial particles are investigated.Comprehensive performance evaluation of Ag/Cu-CTS particles is carried out through the analysis of particle mechanical strength,FT-IR and SEM.The application of Ag/Cu-CTS antibacterial particles in washing machine is evaluated.It is verified that the best antibacterial effect will be performed by Ag/Cu-CTS composite antibacterial particles prepared under the conditions that the concentration of Ag is 40%,the dosage of porogen is 2.5 mL,the concentration of crosslinking agent is 1.0%,and the crosslinking temperature is at 45℃.
