摘　　要：制备了添加不同纳米二氧化钛(TiO_2)含量的竹粉/聚氯乙烯(PVC)复合材料,研究纳米TiO_2对复合材料力学性能和抗菌性能的影响,结果表明,纳米TiO_2能显著提高复合材料的力学性能,且赋予材料对大肠杆菌和金黄色葡萄球菌很好的抗菌性能;当纳米TiO_2质量分数为1.2%时,复合材料的抗菌率大于90%,抗菌效果显著;当纳米TiO_2质量分数为1.6%时,复合材料的抗菌率均超过了99%,且复合材料具有良好的抗菌长效性。Bamboo flour/PVC composites prepared, and the effect of nano-TiO2 on the with different content of nano-TiO2 were mechanical properties and bactericidal activity of the composites was investigated. The results show that nano-TiO2 can obviously improve the mechanical properties of the composites, and the composites show excellent bactericidal activity on the E. eoli and S. aureus. The bactericidal activity of the composites is more than 90% when the content of nano-TiO2 is 1.2 %. When the content of nano-TiO2 is 1.6%, the bactericidal activity of the composites is more than 99%. The composites have good long-time bactericidal activity.
