The development of flexible, intelligent, and lightweight optoelectronic devices based on flexible transparent conductive electrodes (FTCEs) utilizing silver nanowires (AgNWs) has garnered increasing attention. However, achieving low surface resistance, strong adhesion to the flexible substrate, low surface roughness, and green degradability remains a challenge. Here, a composite electrode combining natural polymer cellulose nanofibers (TCNFs) with AgNWs was prepared. This process includes non-covalent interface embedding between TCNFs and AgNWs as well as a strong capillary force between the hydrophilic TCNF substrate and AgNWs during water mist capillary force cold welding. By adding ethanolamine and employing a rapid water mist wetting-drying process (within 10 s), the performance of TCNF/AgNW FTCEs significantly improves with reduced sheet resistance (8.3 Ω sq.
