Silica sols modified with a silver compound are applied onto textile substrates to realize its antibacterial properties. As textile substrates, cotton fabrics are used. The liquid sol recipes are applied by a padding process onto the textiles. Afterwards, a microwave-assisted heating process is applied for drying of the silica sol coating and to form elementary silver nanoparticles. The microwave process is done in a closed autoclave system with process temperatures in the range of 80–140 °C. The process duration is only 5 min short, compared to traditional hydrothermal processes. The coating forming process is strongly determined by the applied process temperature, probably due to boiling and evaporation processes. Lower process temperatures and temperature development used lead to a regular distribution of the silica sol coating on the textile substrates. All prepared coated samples exhibit significant antibacterial properties against the bacteria S. aureus and E. coli. The antibacterial effectiveness increases as a function of silver content and with increasing process temperature of the microwave process. This first experimental set-up can act as first proof-of- concept for effective and fast functionalization of substrates by using microwave technology.

用银化合物改性的硅溶胶被施加到纺织品基材上，以实现其抗菌性能。作为纺织品底物，使用棉织物。液体溶胶配方通过填充工艺施加到纺织品上。然后，应用微波辅助加热工艺干燥硅溶胶涂层并形成单质银纳米颗粒。微波过程在密闭的高压灭菌器系统中完成，过程温度范围为80–140°C。与传统的水热过程相比，该过程持续时间仅短5分钟。涂层的形成过程很大程度上取决于所施加的过程温度，这可能是由于沸腾和蒸发过程所致。较低的工艺温度和使用的温度升高导致二氧化硅溶胶涂层在纺织品基材上的规则分布。所有制备的包被样品均显示出对细菌的显着抗菌性能金黄色葡萄球菌和大肠杆菌。抗菌效果随银含量的增加以及微波工艺过程温度的提高而增加。该第一个实验设置可以作为使用微波技术对基材进行有效，快速功能化的第一个概念验证。
