摘　　要：为制备无规则多孔结构Ni_(3)S_(2)材料,以泡沫镍为基体,基于水热反应法进行无规则多孔结构的Ni_(3)S_(2)材料生长修饰操作,制成具备优良特性的超疏水材料并对其电化学性能进行研究.结果表明,接触角的数值会随着水热反应温度及时间的不同而呈现不同的结果.水热反应温度为180℃、反应时间为6 h的条件下水热反应层表面的水滴接触角达到最大值.此时,水热反应层还会在反应表层形成新的表面物相,这种物相对于提升Ni_(3)S_(2)材料的抗腐蚀性和耐酸碱性有很大帮助.In order to prepare irregular porous structure Ni_(3)S_(2) materials,this paper uses foam nickel as the substrate and hydrothermal reaction method as the theoretical basis to carry out the growth and modification of Ni_(3)S_(2) materials with irregular porous structure.Finally,the super hydrophobic materials with excellent characteristics are prepared and their electrochemical properties are studied.The results show that the values of the contact angle present different numerical results depending on the hydrothermal reaction temperature and the hydrothermal reaction time.The contact angle of water droplets on the surface of the hydrothermal reaction layer reaches the maximum under the condition that the hydrothermal reaction temperature is 180℃and the reaction time is 6 h.At this time,the hydrothermal reaction layer would also form a new surface phase on the surface of the reaction layer,the kind of material is very helpful in improving the corrosion resistance and acid and alkali resistance of Ni_(3)S_(2) materials.
