Abstract
Textured cotton substrates are drawing interest as a new class of nonwetting and nonfouling materials We investigated the effect of temperature solvent and substrate presence on the in situ particle growth process for the production of selfcleaning washresilient and airpermeable superhydrophobic and oleophobic cotton textiles By comparing the size of particles grown in solution with those grown on cotton fibers we show that the uniform solution growth follows a faster reaction rate In general the cotton surface favors the production of hierarchical structures that provide a liquidrepellent behavior when combined with low surface free energy nanocoatings such as an organically modified silane precursor or perfluoro ethers In addition the influence of an oilbased lubricant on the pinning effect was evaluated On the basis of these findings we present a lowcost method to manufacture nanostructured coatings to achieve optimal roughness and liquid repellence
