Abstract

The proposed work aims to functionalize leathers for footwear industry with antimicrobial properties based on Ag–TiO₂ nanoparticles. The synthesis of nanoparticles was carried out by the hydrothermal method with significant advantages in terms of time, energy savings and low cost. Anatase TiO₂ nanoparticles with dimensions below 10 nm were obtained as observed by X-ray diffraction and transmission electron microscopy. Fourier transform infrared spectroscopy showed that the based structure of leather was not modified by the addition of the nanoparticles. The antimicrobial activity was evaluated and it was observed that Ag containing leathers gained antimicrobial activity. In addition, the nanoparticles were found to be non-cytotoxic. This achievement, by itself, should be quite appealing to the footwear industry as it could consist in a solid value-preposition given the commonness of fungal infections promoted by humidity, poor breathability and temperature that promote the expansion of the microflora of the skin.

银- tio2纳米颗粒改性抗菌皮革的研制

提出的工作旨在功能化皮革的鞋业抗菌性能基于Ag-TiO2纳米颗粒。采用水热法合成纳米颗粒，具有省时、节能、成本低等优点。通过x射线衍射和透射电镜观察，获得了尺寸小于10 nm的锐钛矿型TiO2纳米颗粒。傅里叶变换红外光谱表明，纳米颗粒的加入并没有改变皮革的基结构。对其抑菌活性进行了评价，发现含银革具有一定的抑菌活性。此外，纳米颗粒被发现是无细胞毒性的。这一成就，就其本身而言，应该是相当有吸引力的鞋类行业，因为它可以构成一个坚实的价值介词，考虑到真菌感染的普遍性，湿度，不透气和温度促进皮肤微生物群的扩张。
