Caractérisation
CotonLe coton est une fibre végétale qui entoure les graines des cotonniers "véritables"(Gossypium sp.), un arbuste de la famille des Malvacées. Cette fibre est généralement transformée en fil qui est tissé pour fabriquer des tissus. Le coton est la plus importante des fibres naturelles produites dans le monde. Depuis le XIXe siècle, il constitue, grâce aux progrès de l'industrialisation et de l'agronomie, la première fibre textile du monde (près de la moitié de la consommation mondiale de fibres textiles).

| Résumé : |
A simple sol–gel method was proposed to fabricate superhydrophobic cotton fabric (S-fabric) with a water contact angle of 155.6°. A co-condensation process between zirconium hydroxide (Zr(OH)4) and n-dodecyltrimethoxysilane under alkaline condition was presented. The functionalized Zr(OH)4 NPs with long-chain alkyl groups (–(CH2)11CH3) offered both hierarchical roughness and lower surface energy for S-fabric. The functional groups, surface morphology, element distribution, and surface roughness changes were examined by FTIR, SEM, EDS, and 3D optical profiler, respectively. And the results indicated that the cotton fabric was successfully modified. The obtained cotton fabric retained chemical stability after 72 h immersion in different extreme conditions, and mechanical durability after 200 cm of abrasion length. The S-fabric could be applied in the separation of oil–water mixture (n-hexane, n-heptane, n-dodecane, cyclohexane and kerosene) with the high efficiency (> 96%), and the efficiency remained stable after 50 separation cycles (n-dodecane and n-hexane). The facile preparation, chemical and mechanical stability, high separation efficiency, and good reusability of S-fabric indicated the potential practical application value in oil/water separation. |
