Cotton fabrics exhibiting superhydrophobic and antibacterial properties were prepared through sonochemical coating technique. Substantial amount of copper nanoparticles (Cu-NPs) could be deposited on the cotton fabric through sonochemical process using ultrasonic irradiation in water. The effects of Cu-NPs concentration, sonication time and NaOH concentration on the Cu-NPs coating behavior were investigated by FE-SEM observation, EDS elemental analysis and contact angle measurement. Regarding the media for the sonochemical process, alkaline solution was more effective than distilled water due to mercerization effect to make cotton swelled and soft. It was also found that Lotus effect (superhydrophobicity) could be successfully introduced to the hydrophilic cotton fabrics ascribed to micro- and nano-bumps formed by Cu-NPs. The maximum contact angle obtained in the study was 145 degree for the sample coated at 20 mM Cu-NPs and 15 wt% NaOH, respectively. Moreover, antibacterial properties could be added to the fabric by coating of Cu-NPs without further treatment.

通过声化学涂层技术制备了具有超疏水和抗菌性能的棉织物。可以使用超声波在水中通过声化学过程将大量的铜纳米颗粒（Cu-NPs）沉积在棉织物上。通过FE-SEM观察，EDS元素分析和接触角测量研究了Cu-NPs浓度，超声处理时间和NaOH浓度对Cu-NPs涂层行为的影响。关于声波化学处理的介质，由于碱化作用，碱溶液比蒸馏水更有效，因为丝光作用使棉花膨胀并变软。还发现，归因于由Cu-NP形成的微凸点和纳米凸点的亲水性棉织物，可以成功地引入莲花效应（超疏水性）。在研究中获得的最大接触角分别为20 mM Cu-NPs和15 wt％NaOH涂覆的样品的145度。而且，可以通过涂覆Cu-NP而将抗菌性能添加到织物中，而无需进一步处理。
