Superhydrophobic surfaces by creating surface roughness followed by coating with low-surface-energyfluorinated materials have been intensively developed on cotton fabrics. However, exploring superhydrophobic surfaces withnon-fluorine components and further improving their attachment with cotton fabrics is still challenging. Herein, wedeveloped a superhydrophobic surface on cotton fabric by dip coating with hexadecylamine (HDA) modified coppernanowires (Cu NWs) based on the coordination between Cu atoms and amine groups. The HDA modified Cu NWs not onlycreated surface roughness, but also decreased the surface energy, leading to a superhydrophobic cotton fabric with watercontact angle of 164 °±2.0 °. Furthermore, ultrasonic washing and tape peeling tests exhibited the Cu NWs were adheredtightly to the surface of cotton fibers, owing to the strong hydrogen bond between amine groups on HDA molecules andhydroxyl groups on cotton fibers. In addition, the superhydrophobic cotton fabric showed excellent antifouling, oil-waterseparation and infrared reflection properties. It is believed that this facile method provide promising industrial applicationsfor fabricating superhydrophobic surfaces on other substrates.
