介绍了天然胶乳泡沫（NRLF）纳米银颗粒（SNP）的合成和表征。用三柠檬酸钠还原硝酸银（AgNO3）合成的SNP被原位吸附在NRLF基质上。对革兰氏阳性金黄色葡萄球菌和革兰氏阴性大肠杆菌的抑菌活性进行了定性和定量检测。结果发现，所得的NRLF样品对所谓的两大类细菌的生长有很强的抑制作用。SEM和EDX分析表明，泡沫橡胶基体上吸附的银颗粒为纳米级。
Synthesis and characterization of silver nanoparticles (SNP) incorporated natural rubber latex foam (NRLF) is described. SNP synthesized by reducing of Silver Nitrate (AgNO3) with Tri-Sodium Citrate (TSC) were adsorbed in-situ on to the NRLF matrix. Antimicrobial activities were tested by qualitatively and quantitatively against Gram positive Staphylococcus aureus and Gram negative Escherichia coli. It was found that the resultant NRLF samples inhibit the growth of so called two main groups of bacteria in very strong manner. The SEM and EDX analysis provided evidence of adsorbed silver particles on the foam rubber matrix are in nanometer size.
