we introduce a high-conductivity metal fabric-liquid metal composite electrode. The liquid metal compensation layer is used to effectively fill the warp and weft pores of the fabric, constructing a continuous and dense conductive network, which improve the problem of electric field distortion caused by the high surface tension of the metal-based material, thereby enhancing the uniformity and stability of the device's luminescence. Due to its excellent flexibility and continuous conductive network, this composite electrode can also maintain stable conductivity under dynamic bending conditions. Further, by using PEG-modified BaTiO3, a dynamic interface with Janus-like characteristics is constructed. PEG form a flexible organic shell layer on the BaTiO₃ surface, preventing particle aggregation and promoting its uniform dispersion in the PVDF-HFP matrix, effectively improving the interfacial compatibility between inorganic fillers and polymer matrix, enhancing interface polarization, and thereby improving the luminescence performance and stability of the device. Additionally, the fabricated device can achieve electromagnetic shielding function, effectively limiting the leakage of electrical signals and blocking the electromagnetic radiation of the device during the high-frequency AC driving process, reducing the interference from the surrounding environment. To expand the application scope of the device, we prepare devices with different patterns on the electromagnetic shielding fabric and conduct performance tests. The results show that it could effectively isolate electromagnetic radiation interference; at the same time, by integrating touch sensing devices, this device can also be applied in the protection and control fields of precision instruments.本研究提出一种高导电金属织物-液态金属(liquid metal)复合电极。该液态金属补偿层可有效填充织物的经纬孔隙，构建出连续致密的导电网络，从而改善金属基材料高表面张力引发的电场畸变问题，进而提升器件发光的均匀性与稳定性。得益于优异的柔韧性与连续导电网络，该复合电极在动态弯折工况下仍可保持稳定的导电性能。进一步，通过聚乙二醇(PEG)改性钛酸钡(BaTiO₃)，可构建具有类贾努斯(Janus)特性的动态界面。PEG可在BaTiO₃表面形成柔性有机壳层，抑制颗粒团聚并促进其在聚偏氟乙烯-六氟丙烯共聚物(PVDF-HFP)基体中均匀分散，有效提升无机填料与聚合物基体间的界面相容性，增强界面极化效应，进而改善器件的发光性能与稳定性。此外，所制备的器件可实现电磁屏蔽(electromagnetic shielding)功能，在高频交流驱动过程中，能够有效限制电信号泄漏并阻隔器件自身的电磁辐射，降低外界环境带来的干扰。为拓展该器件的应用范围，研究团队在电磁屏蔽织物上制备了不同图案的器件并开展性能测试。测试结果表明，其可有效隔绝电磁辐射干扰；同时，通过集成触摸传感装置，该器件还可应用于精密仪器的防护与控制领域。
