Polyethylene terephthalate (PET) foils were activated with piranha solution and grafted with selected amino compounds (cysteamine, ethylenediamine or chitosan) and then with borane compounds. Changes in their surface properties after particular modification steps were examined using electrokinetic analysis, X-ray photoelectron spectroscopy (XPS), goniometry and UV-vis spectroscopy. Several tests showed that the presence of some amino compounds and one borane cluster significantly improved the antimicrobial properties of the composites investigated. In particular, they exhibited strong antibacterial activity against but only weak activity against . The samples modified with amino compounds and subsequently with borane clusters were luminescent under UV lamp irradiation. Therefore, the nanocomposites consisting of (cheap) polymer and (more expensive) borane could be used in luminophore development, medicine or environmental protection.
聚对苯二甲酸乙二酯（PET）箔用王水进行活化处理，然后与选定的氨基化合物（半胱胺、乙二胺或壳聚糖）进行接枝，接着再与硼烷化合物进行接枝。在特定的改性步骤之后，使用电动分析、X射线光电子能谱（XPS）、测角术和紫外可见光谱对其表面性质的变化进行了研究。多项测试表明，某些氨基化合物和一种硼烷簇的存在显著改善了所研究复合材料的抗菌性能。特别是，它们对 表现出很强的抗菌活性，但对 仅表现出较弱的活性。用氨基化合物然后再用硼烷簇改性的样品在紫外灯照射下会发光。因此，由（廉价的）聚合物和（较昂贵的）硼烷组成的纳米复合材料可用于发光体开发、医学或环境保护领域。
