Preparation of Chlorohexidine Acetates-Silica Composite Antibacterial Materials and Their Performances
摘要
Abstract
Chlorohexidine acetates-silica composite antibacterial materials were prepared by the method of ammonia catalytic common gel with tetraethoxysilane and chlorohexidine acetates as raw materials. Low-temperature N2 adsorption, SEM and FTIR methods were employed to investigate specific surface area, particle morphology and functional group on the sample surface. Bacteriostasis circle experiments were conducted to assess the dissolving antibacterial performance of the samples upon aureus staphylococcus and thermal stability of materials. The results show that chlorohexidine acetates and silica in chlorohexidine acetates -silica composite antibacterial materials are highly dispersed. The materials have good heat resistance. With calcinations under 200 ℃ in air for 30 min, the antibacterial performance of the composite can be successfully observed. The composite materials prepared exhibite obvious digestion antibacterial ability upon aureus staphylococcus. They can be tried as heat resistant antibacterial additives which are applied into polymers needing hot working.关键词
