透明导电弹性体是一种新兴的可拉伸电子产品平台，其吸引力在于其能够维持高物理变形，同时仍能实现光学/电学功能。聚深共晶溶剂（DESs）具有低成本、绿色制造、无毒、免后处理等优点，是一种新型透明导电弹性体。在这里，我们报告了一种基于丙烯酸/胆碱-氯化物DES光聚合的3D图图化（海星型）、透明（透光率~ 81%）、可拉伸（应变高达150%）和导电（~ 0.2 S m−1）弹性体。透明度、弹性、导电性和图图化的结合使聚（DES）弹性体可以用作柔性触觉/应变传感器。我们的方法具有开发聚醚（DESs）新应用的潜力，并为制造全有机透明导电弹性体开辟了一条新的强大途径，可用于未来柔性电子产品的无数应用。
Transparent conductive elastomers are an emerging platform for stretchable electronics, attractive due to their ability to sustain high physical deformations while still fulfilling optical/electrical functions. Poly(deep eutectic solvent)s (DESs) can serve as a new type of transparent conductive elastomers as a result of their low cost, green fabrication, non-toxicity and post-treatment-free advantages. Here, we report a 3D patternable (starfish type), transparent (transmittance of ∼81%), stretchable (strain up to 150%), and conductive (∼0.2 S m−1) elastomer based on the photopolymerization of the acrylic-acid/choline-chloride DES. The combination of transparency, elasticity, conductivity and patternability allows the poly(DES) elastomers to serve as flexible tactile/strain sensors. Our methodology has the potential to exploit the new application of poly(DESs), and opens up a new powerful route to fabricate all-organic transparent, conductive elastomers for a myriad of applications in future flexible electronics.
