In this study, general functionalization of cotton fabric by loading silver nanowires (AgNWs) on cotton surface is reported. Initially, AgNWs were synthesized by a polyol process and then were conformal coated onto individual cotton fibers through a simple dip and dry process. SEM images revealed a thin and uniform AgNWs coating on the cotton microfibers which was supported by a surface chemical analysis by EDX. The average electrical surface resistivity of the fabric coated with conductive network of AgNWs was measured to be 27.4 S2/sq. Incubating the modified fabric with either Escherichia coli or Staphylococcus aureus demonstrated that the fabric had substantial antimicrobial capacity against both Gram-positive and Gram-negative bacteria (100% microbial death). The fabric also showed excellent UV-blocking ability with the UV protection factor of 113.14. The fluorosilane coated AgNWs-loaded fabric displayed stable superhydrophobicity with CA and SHA values of 156.2 +/- 3.2 degrees and 7 degrees, respectively. (C) 2014 Elsevier Ltd.
