摘    要:基于简单的液相法,以硫代硫酸钠和氯化铜为原料在铜片表面上构筑了具有微/纳米双尺寸粗糙度的硫化铜膜.用X射线衍射(XRD)仪、扫描电镜(SEM)、能量色散X射线(EDX)光谱仪及光学视频接触角仪对处理前后的铜表面进行了表征和分析.处理后的超亲水铜表面经硬脂酸修饰后具有超疏水效应,静态接触角高达161°,5μL水滴滚动角低至2.5°左右.超疏水性能归因于表面具有双尺寸粗糙度和低表面能的硬脂酸.该方法简单,无需复杂制备过程和苛刻设备,所得超疏水铜表面具有优异的不粘附性、长时间储存的稳定性和一定的耐摩擦性能.

关 键 词:液相法  超疏水    硬脂酸  耐摩擦性

Abstract:A copper sulfide film with dual scale micro-and nano-structured roughness was constructed on copper foil via a facile solution-phase method using the sodium thiosulphate and cupric chloride as raw materials.The resulting film was characterized by X-ray diffraction(XRD),scanning electron microscopy (SEM),energy dispersive X-ray(EDX)spectrometer,and contact angle measurements.After stearic acid hydrophobization,the film exhibited a water contact angle of 161°and a sliding angle of 2.5°for a 5μL water droplet.The superhydrophobicity was attributed to a combination of the dual scale roughness at the micro-and nano-meter levels and the low surface energy of the stearic acid coating.This is a simple synthetic methodology requiring no complex or harsh equipment.The copper surface obtained has the excellent non-sticking property,long-term storage stability,and relatively good anti-abrasion property.
Keywords:Solution-phase synthesis  Superhydrophobicity  Copper  Stearic acid  Anti-abrasion
