摘　　要：金属铜具有优异的导电性、导热性和延展性,被广泛应用于日常生活和传统工业生产领域,并在新一轮能源革命中发挥重要作用。然而,纯铜材料极易被氧化,应用过程中的各种腐蚀导致了不可避免的性能降低和严重的经济损失。本文报道了一种通过多种辐射/光引发(紫外、可见光、电子束和高能γ射线)二氧化碳阴离子自由基(CO_(2)^(·-))与金属铜表面进行配位,构筑钝化层来制备抗氧化铜材料的低碳高效新思路。该新型防腐技术可以在保持铜导电导热性的同时,赋予其在多种环境下的抗氧化性能。区别于传统防腐技术,该技术无需高温高压,并大大降低电能消耗和环境污染。此外,该技术可以利用自然光处理各种尺寸和形状的铜材料,并可利用工业电子束实现快速、大规模的抗氧化铜制备。Owing to its electrical and thermal conductivities and ductility,copper metal is extensively used in daily life and conventional industrial production.Moreover,it plays an essential role in the new energy revolution.However,copper materials are highly susceptible to oxidation and various types of corrosion during application,which inevitably lead to performance degradation and severe economic losses.This study reports a novel strategy for preparing antioxidant copper materials by coordinating photo-induced carbon dioxide anion radicals(CO_(2)^(·-)),which are generated by ultraviolet(UV),visible,electron beam,and high-energyγ-rays,with metallic copper surfaces to construct an anti-corrosive binding layer.This novel anti-corrosion technique maintains the electrical and thermal conductivities of copper,while introducing anti-corrosive properties in diverse environments.Compared with conventional anti-corrosion strategies,this technique does not require a high temperature and pressure,and significantly reduces power consumption and environmental pollution.Additionally,the technique is applicable to various sizes and shapes of copper materials and enables the rapid,large-scale preparation of anti-corrosive copper using industrial electron beams.
