摘要:
将AgCl晶体和聚四氟乙烯(PTFE)粉末(质量比1:1)混合物作为靶材,分别在石英玻璃、单晶硅片、聚甲基丙烯酸甲酯有机玻璃(PMMA)和镀铝聚酯膜基底上,通过低功率电子束蒸发法沉积一定厚度的含Ag/聚合物复合薄膜。采用傅里叶变换红外光谱仪(FT-IR)、X线光电子能谱仪(XPS)、场发射扫描电子显微镜(FESEM)、透射电子显微镜(TEM)和原子力显微镜(AFM)分析薄膜成分、结构和表面形貌,运用接触角测试仪评估薄膜表面的疏水性,采用琼脂扩散法测试其抗菌性能。结果表明:复合薄膜厚度约为490 nm,表面存在明显的两相结构,即以C=C、C—C、C—CFn、C—F、—CF2基团形成的聚合物基膜里分散着纳米Ag和AgCl颗粒; 石英和硅片基底上复合薄膜的接触角分别为108.41°和104.38°,表现为疏水性,对标准菌株金色葡萄球菌和大肠杆菌都具有明显的抗菌效果,其中对金色葡萄球菌的抗菌能力比大肠杆菌更显著。
Abstract:
AgCl crystals and polytetrafluoroethylene(PTFE)powder mixed together at the mass ratio of 1:1 as target was used to deposit Ag/polymer composite film with a certain thickness on base of the quartz glass,silicon,polymethyl methacrylate(PMMA)and polyethylene terephtalate film coated by aluminium substrates by electron beam evaporation(EBD). The composition,structure and surface morphology of composite films were characterized by Fourier transform infrared spectroscopy(FT-IR),X-ray photoelectron spectroscopy(XPS),field emission scanning electron microscopy(FESEM),transmission electron microscopy(TEM),and atomic force microscopy(AFM). The hydrophobic property was assessed by contact angle test while antibacterial property was tested by agar diffusion method. Results showed that the thickness of composite films was about 490 nm. The surface displayed two-phase structure,with Ag nanoparticles and AgCl nanoparticles dispersing in PTFE polymer film, was comprised of C=C,C—C,C—CFn,C—F,and —CF2 groups. Contact angles were 108.41° and 104.38° for films on quartz and silicon substrates respectively,which performed hydrophobic. Ag-doped composite films had antibacterial effects against Staphylococcus aureus and Escherichia coli,with the antibacterial ability against Staphylococcus aureus more obvious and more effective.
