采用原位掺杂聚合法制备聚苯胺/CuO纳米复合粒子,对其进行了表征,考察了其催化性能和抗菌性能.结果表明,聚苯胺在CuO表面包覆,得到棒状核-壳结构的聚苯胺/纳米CuO复合粒子,其具有良好的催化性能,能加速H2O2分解,累积产气1500 m L;随CuO含量增加,复合粒子电导率明显下降,导电性能逐渐减弱,纳米CuO含量为0.6g时,导电能力很弱,电导率为0.02S/cm.随CuO含量增加,复合粒子抗菌性能逐渐增强,金黄色葡萄球菌和大肠杆菌的抑菌圈直径分别达35.8和19.6mm.
The polyaniline / CuO nanocomposite particles were prepared by in-situ doping polymerization method, and their catalytic and antibacterial properties were investigated. The results showed that polyaniline was coated on the surface of CuO to obtain poly Aniline / nano CuO composite particles, which has good catalytic properties, can accelerate the H2O2 decomposition, the cumulative gas production 1500 m L; with the increase of CuO content, the conductivity of composite particles decreased significantly, the conductivity decreased gradually, when the nano CuO content of 0.6g , The conductivity is very weak, the conductivity is 0.02S / cm. With the increase of CuO content, the antibacterial properties of the composite particles gradually increase, and the diameters of the antibacterial circles of Staphylococcus aureus and Escherichia coli reach 35.8 and 19.6mm, respectively.
