    摘要:

    本實(shí)驗(yàn)采用兩步水熱法在鉭基體表面制備出摻雜Cu2+的Ta2O5納米棒薄膜。采用XRD、SEM、XPS等方法分析了材料的物相和表面微觀結(jié)構(gòu)。用ICP檢測了樣品在生理鹽水中離子析出濃度,最后通過平板計(jì)數(shù)法檢驗(yàn)了不同含量銅摻雜Ta2O5薄膜的抗菌能力。結(jié)果表明,通過兩步水熱處理,在鉭表面生成了簡單斜方晶體結(jié)構(gòu)的Ta2O5納米棒陣列,Cu2+的摻雜不會對納米棒薄膜的微觀形貌和物相造成顯著影響。隨時間的增加,摻銅薄膜的銅離子析出速率逐漸趨于平緩。平板計(jì)數(shù)法表明,Cu2+ 的摻雜量達(dá)到2.68At%時,銅摻雜Ta2O5納米棒薄膜的抗菌性能最好,抗菌率達(dá)99.2%。

    Abstract:

    Ta2O5 nanorod films doped with Cu2+ were prepared by a two-step hydrothermal method on tantalum. XRD, SEM and XPS were used to analyze the phase and surface microstructure of the materials. The ion precipitation concentration of samples in normal saline was detected by ICP, and the antibacterial ability of Ta2O5 films with different content of copper was tested by plate counting method. The results showed that Ta2O5 nanorods with simple rhombic crystal structure were generated on the tantalum surface by two-step hydrothermal treatment, and the doping of Cu2+ did not significantly affect the microstructure and phase of nanorods. With the increase of time, the precipitation rate of copper ions in copper-doped films gradually tends to be flat. The result of plate counting showed that when the doping amount of Cu2+ reached 2.68At%, copper doped Ta2O5 nanorod films had the best antibacterial performance and the antibacterial rate reached 99.2%.
