  Abstract

The superhydrophobic surface is easy to lose the superhydrophobicity in the practical applications, due to the fact that the micro- and nanoscale rough structure is easily damaged. Therefore, it is one of the challenges to endow solid surface with durable superhydrophobic property. In this work, the environment-friendly superhydrophobic cotton fabric was prepared by dip-coating methodology. Meanwhile, the cotton fabric was endowed with durable superhydrophobicity. Herein, the octadecylamine was utilized to reduce the surface free energy of cotton fabric. However, octadecylamine was only adsorbed on the fabric surface. Therefore, the hydrophobic resin was employed to supply enough adhesion force. As a result, the limitation that traditional methods frequently utilize additional nanoparticles to construct hierarchical rough surfaces was broken. The water contact angles of the coated cotton fabric at room temperature and 70 oC reached 154.4짹0.6 o and 120짹1.1 o, respectively. Moreover, the coated cotton fabric still reserved superhydrophobic property after 30th cycle셲 abrasion and exhibited excellent hydrophobicity after 500th cycle셲 abrasion. In addition, the surface free energy of original cotton fabric reduced by 54.7 % so that the coated cotton fabric had outstanding repellency to hydrochloric acid, sodium hydroxide solution, coffee and sodium chloride solution, respectively.
