Nano-functionalization of textiles for superhydrophobicity and UV blocking

Having water repellency and ultraviolet (UV) protection are one of the few important properties that is necessary in the fabrication of textiles. In this report, cotton fabrics were treated with CeO2 sol to fabricate surface roughness so as to enhance superhydrophobicity. The methodology of synthesi...
