Preparation and properties of superhydrophobic cotton fabrics
Keywords:Superhydrophobic, Cotton fabric, Maleic-anhydride grafted poly[styrene-b-(ethylene-cobutylene)-b-styrene
AbstractIn this study, superhydrophobic cotton fabric was prepared by coating maleic-anhydride grafted poly[styrene-b-(ethylene-co-butylene)-b-styrene] (SEBS-g-MA) triblock copolymer solutions containing calcium carbonate (CaCO3) particles. SEBS-g-MA solutions were prepared using single solvent (toluene and tetrahydrofuran (THF)) and mixed solvent (toluene: ethanol (EtOH) and THF: EtOH). Cotton fabrics were treated with the prepared solution using padding technique. All coated fabrics exhibited a water contact angle (WCA) of more than 100Â°. Optimum WCA values were observed when THF and 90:10 toluene: EtOH were employed. In case of CaCO3 particles addition, 6% W/V CaCO3 could impart the highest WCA value of 154Â°. However, the durability of the coatings was decreased after washing test as witnessed by the decrease in WCA value. Interestingly, fabricsâ€™ WCA values after rubbing test were found higher than those before testing due to rougher fabric surface. Finally, coating of SEBS-g-MA onto cotton fabric insignificantly affected the color appearance of coated fabric, judged by an insignificant change in CIE L*a*b* values.
