Description

一种可生物降解柔性电导线的制备方法
技术领域
本发明涉及新型电线复合材料技术领域，尤其涉及一种可生物降解柔性电导线的制备方法。
背景技术
随着科技的进步，便捷化、小型化及高性能化是当前电子产品发展的主流趋势，导致电子产品更新换代速度加快，电子产品的重要配件之一的导电线，随着电子产品的升级及更新，成为废弃物；同时，人们在使用电线的过程中，因强力拉伸、不规则折叠等原因造成电线中的导电丝断裂，导致整个电线失去应用功能，使得整个电线成为垃圾而丢掉，这有极大的造成环境污染。
市场上现有的电线主要是铜、铝等金属线作为导电芯，橡胶、塑料作为包覆层，通过共挤出成型加工为导电线，其断裂伸长率一般不超过15%，因高频率不规则折叠、缠绕和强力拉伸等原因，电线断裂导致无法使用的事情经常发生。同时，现用电线的包覆层材料在自然环境中需数十件甚至上千年才能降解。导电线因更新换代或损坏导致无法使用则直接变成电子垃圾，对人体及环境产生恶劣的影响。
为延长导电线高效服役时间，缓解电子垃圾围城的现状，需要一种可生物降解的柔性导线，不仅解决现有导电线因高频率折叠、缠绕、强力拉伸导致的电线断裂现象，而且还避免废弃的导线对人体及环境造成的危害。
