A facile fast laser nanoscale welding process uses the plasmonic effect at a nanowire (NW) junction to suppress oxidation and successfully fabricate a Cu-NW-based percolation-network conductor. The "nanowelding" process does not require an inert or vacuum environment. Due to the low-temperature and fast-process nature, plasmonic laser nanowelding may form Cu-nanowire networks on heat-sensitive, flexible or even stretchable substrates.
一种简便的快速激光纳秒焊接工艺利用纳米线(NW)结处的等离子体效应来抑制氧化,成功制备了基于 Cu-NW 的渗流网络导体。“纳秒焊接”工艺不需要惰性或真空环境。由于其低温和快速加工的特点,等离子体激光纳秒焊接可以在热敏、柔性甚至可拉伸的衬底上形成 Cu 纳米线网络。
