The conducting metallic grid is a prominent viable candidate for an alternative to indium tin oxide for optoelectronic devices. This metallic grid tends to oxidize quickly, and to avoid oxidization, a passivation layer must be added, which drastically compromises the transmittance. The fabrication of a highly flexible, highly transparent, and conductive copper grid electrode with an outstanding sheet resistance of 0.11 Ω □⁻¹, and excellent transparency of 93.13% is reported. This copper electrode resists oxidization with the help of poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS), and even after exposing the electrode to the ambient atmosphere, it shows excellent sheet resistance of 0.12 Ω □⁻¹. This is achieved by the in situ formation of an oxidization-resistive light-absorbing PEDOT:PSS layer that encapsulates the Cu microparticles during electrodeposition. The electrode shows excellent mechanical stability with good electromagnetic interference shielding of 19 dB. Moreover, the electrode is developed as a thin film heater, and subjects to electrochemical analysis, which shows a specific capacitance of 81.58 mF cm⁻² for supercapacitor application.

用于透明加热器和电化学超级电容器应用的高透明导电电极的自封装铜网格

导电金属网格是光电设备中氧化铟锡的替代品的一个突出的可行候选者。这种金属网格往往会迅速氧化，为避免氧化，必须添加钝化层，这会大大降低透光率。报道了一种高度柔性、高度透明和导电的铜栅电极的制造，其具有 0.11 Ω □ ^-1的出色薄层电阻和 93.13% 的出色透明度。这种铜电极在聚（3,4-亚乙基二氧噻吩）聚苯乙烯磺酸盐（PEDOT：PSS）的帮助下抗氧化，即使将电极暴露在环境大气中，它也表现出 0.12 Ω □ -1 的优异薄层^电阻. 这是通过原位形成抗氧化光吸收 PEDOT:PSS 层来实现的，该层在电沉积过程中封装了 Cu 微粒。该电极具有出色的机械稳定性和 19 dB 的良好电磁干扰屏蔽能力。此外，该电极被开发为薄膜加热器，并进行了电化学分析，其比电容为81.58 mF cm ^-2，可用于超级电容器应用。
