Bioinspired High-Adhesion Metallic Networks as Flexible Transparent Conductors

While metallic networks, proposed recently as a replacement for transparent conducting oxides, show superior optoelectronic performance and mechanical flexibility, their adhesion to flexible substrates remains a problem. In this work, a high adhesion metallic network inspired by the ground-gripping functionality of bamboo roots is developed. This network shows not only excellent optoelectronic performance but also superb adhesion to flexible substrates could be beneficial for flexible electronics.
