合成具有高透明性和自修复能力的导电弹性体，同时采用简便、环境友好的制备工艺，是一个极具吸引力的课题。在这里，我们展示了高度透明的，自我修复的导电弹性体的基础上的协同氢键聚（可聚合的深共熔溶剂）（聚（PDES））和植酸（PA）分子之间的相互作用。该混合网络弹性体在没有任何其他外部刺激的情况下表现出快速的自愈性能（2秒内），并且在48小时内表现出优异的自愈效率（91.5%）。聚（PDES）-PA弹性体是高度透明的（平均透射率为93%）、固有导电的（离子电导率为7.8 × 10（-4）S cm（-1））和可拉伸的（应变高达1300%）。此外，可愈合的导电聚（PDES）-PA弹性体监测人类活动的能力，无论是之前还是之后被损坏。我们相信这种动态键操作是设计和合成各种透明，自修复，导电弹性体的强大策略，用于多用途。
It is attractive, though it is very challenging, to synthesize conductive elastomers with high transparency and self-healing ability, simultaneously with facile and environmentally friendly preparation process. Here we demonstrate the fabrication of highly transparent, self-healing conductive elastomers based on synergistic hydrogen bonding interactions between poly(polymerizable deep eutectic solvent) (poly(PDES)) and phytic acid (PA) molecules. The hybrid network elastomers showed a fast self-healing property (within 2 s) without any other external stimuli and excellent self-healing efficiency (91.5%) within 48 h. The poly(PDES)-PA elastomers were highly transparent (an average transmittance of 93%), intrinsically conductive (an ionic conductivity of 7.8 x 10(-4) S cm(-1)) and stretchable (strains up to 1300%). Furthermore, the abilities of healable & conductive poly(PDES)-PA elastomers to monitor the human activities retained no matter before or after being damaged. We believe this kind of dynamic bond manipulation is a powerful strategy to design and synthesize various transparent, self-healing, conductive elastomers for versatile applications.
