HypothesisCysteic acid functionalized mineral oxide nanoparticles can be used to impart superhydrophilic performance on a range of woven and non-woven fabrics.ExperimentsWoven and non-woven fabrics spray and dip coated alumina and iron oxide based cysteic acid functionalized mineral oxide nanoparticles, were characterized by SEM, EDX and the change in water contact angle was measured or where the increased hydrophilicity was sufficiently great that the time for the adsorption of the water droplet was measured.FindingsFabrics showed a remarkable increase in the hydrophilicity upon coating with cysteic acid functionalized mineral oxide nanoparticles, although alumina-based materials performed better than the iron oxide homologs. Untreated spunlace polypropylene (contact angle = 147.5°) shows the greatest change after CAMO treatment to a water absorption time of 15 ms.
