Multi-gradient wettability copper wire array and preparation method and application thereof
The invention discloses a preparation method for a multi-gradient wettability copper wire array. The preparation method comprises the following steps that red copper wires are ultrasonically cleaned by a hydrochloric acid solution, acetone and ethyl alcohol in sequence, and are dried after cleaning is completed; the plurality of red copper wires are tightly arranged, and bonded with a conductive adhesive to obtain a copper wire array; the obtained copper wire array is vertically put into a copper sulfate solution, electrolysis is carried out by taking the copper wire array as an anode and a copper sheet as a cathode, and liquid leakage is carried out for gradient electrochemical corrosion in the electrolysis process to obtain a conical copper wire array; and the obtained conical copper wire array is vertically placed into a mixed solution of sodium hydroxide and absolute ethyl alcohol with the conical top facing upwards, and electrolysis is carried out by taking the conical copper wire array as the anode and the copper sheet as the cathode to obtain the multi-gradient wettability copper wire array. The obtained multi-gradient wettability copper wire array can achieve rapid and continuous water collection, is high in water collection efficiency, large in water collection amount, low in preparation cost, simple in preparation method, and long in service life, and can be used for fog collection in arid foggy areas and coastal little-rain areas.
本发明公开了一种多梯度浸润性铜丝阵列的制备方法，包括以下步骤：将紫铜丝依次用盐酸溶液、丙酮、乙醇进行超声清洗，清洗完成后烘干；将多根紫铜丝紧密排列，用导电胶粘连，得到铜丝阵列；将所得铜丝阵列竖直放入硫酸铜溶液中，以铜丝阵列为阳极，以铜片为阴极进行电解，电解过程中漏液，进行梯度电化学腐蚀，得到锥形铜丝阵列；将所得锥形铜丝阵列锥顶朝上竖直放入氢氧化钠和无水乙醇的混合溶液中，以锥形铜丝阵列为阳极，以铜片为阴极进行电解，得到的多梯度浸润性铜丝阵列能够实现快速、连续的水收集，集水效率高、集水量大，并且制备成本低廉、制备方法简单、使用年限长，可用于干旱多雾地区以及沿海少雨地区的雾气收集。
