摘要
将经表面处理的无机抗菌粒子制成抗菌母粒 ,与聚丙烯 (PP)熔融共混制备了抗菌PP复合材料 ;采用扫描电镜观察抗菌粒子在PP中的分散状况并测试复合材料的性能。结果表明 :抗菌粒子用量为 1%时 ,抗菌粒子在PP中分布均匀 ,无团聚现象 ,与基体树脂具有较好的相容性 ;复合材料具有良好的广谱抗菌性能 ,抑菌率都能达到 92 %以上 。
Antibacterial mast erbatches were prepared by melt blending PP with surface-modified inorganic part icles containing silver,which were added into PP to prepare antibacterial compos ites The dispersion of the inorganic pa rticles in PP was examined by means of S EM,and the property of the composite was studied The results showed when the an tibacterial particles content was 1%,the particle dispersed well in PP and had g ood compatibility with matrix resin,and the composites had a wide antibiogram ab ove 92% to many kinds of bacteria The u se of antibacterial particles had almost no effect on the mechanical properties of the composite
