摘　　要：针对金属空气电池阳极自腐蚀问题,采用静电纺丝方法制备了ZnO@PAN抗腐蚀薄膜。该薄膜能够有效抑制碱性电解质条件下金属空气电池的阳极自腐蚀,腐蚀抑制率高达85.7%。同时,该薄膜兼具良好的力学特性,可适用于柔性能源器件。电化学和力学测试结果表明,ZnO@PAN抗腐蚀薄膜在疲劳拉伸后依然具备良好的腐蚀抑制性。随ZnO@PAN抗腐蚀薄膜中PAN含量的增加,其腐蚀抑制性减弱,但力学拉伸性能增强。将抗腐蚀薄膜应用于柔性金属空气电池时,需综合考虑应用场景,选用合适PAN含量的抗腐蚀薄膜。本实验所制备的ZnO@PAN抗腐蚀薄膜能够为金属电极提供有效保护,且具有优良的力学性能,在柔性可穿戴电子产品领域具有广阔的应用前景。Aiming at the self-corrosion problem of the metal-air battery anode,the ZnO@PAN anti-corrosion film was prepared by electrospinning.The film can effectively inhibit the anode self-corrosion of metal-air batteries with alkaline electrolyte,and the corrosion inhibition rate is as high as 85.7%.At the same time,the film has good mechanical properties and could be applied to flexible energy devices.The electrochemical and mechanical tests show that the ZnO@PAN anti-corrosion film still has excellent corrosion inhibition after fatigue bending.With the increase of PAN content in the ZnO@PAN anti-corrosion film,the corrosion inhibition was weakened,but its mechanical tensile properties were enhanced.In order to apply the anti-corrosion film to the flexible metal-air battery,it is necessary to consider the application scenarios and select the anti-corrosion film with the appropriate proportion of PAN content comprehensively.The ZnO@PAN anti-corrosion film prepared in this experiment can provide effective protection for metal electrodes,and has excellent mechanical properties,which has broad application prospects in the field of flexible wearable electronic products.
