DOIAbstract
Based on the philosophy of Green Chemistry, in order to grant antimicrobial properties to fabrics, in this work a 100% cotton fabric was used impregnating silver (Ag) and zinc oxide (ZnO) with the addition of carbon extracted from disused batteries, in the intuition of reuse them in a conscious and relevant way. For this, a simple and greener chemical route that occurs at low temperatures was used, the silica-based sol-gel method, which requires a precursor, in this case, tetraethyl orthosilicate (TEOS), and a catalyst to generate the basic hydrolysis using ammonium hydroxide. To evaluate the durability of the coating on the fabric, it was subjected to several wash cycles. Finally, its antimicrobial activity against fungal and bacterial str...
