在这里，我们报告了PET基底上的高度透明和灵活的AgNW/SWCNT混合网络，结合等离子体焊接，以确保在严重弯曲下机械和电气性能的稳定性。等离子体焊接在AgNW的接合处产生局部加热和焊接，并导致AgNW和SWCNT之间以及混合结构和衬底之间的强粘附。等离子体激元处理的AgNW/SWCNT混合膜的初始薄层电阻为26 Ω sq（-1），在400-2700 nm的波长范围内具有>90%的光学透射率。在弯曲半径为5 mm的凸/凹弯曲200次循环后，薄层电阻从26 Ω sq（-1）变为29 Ω sq（-1）。这种与等离子体焊接工艺相结合的混合结构提供了优异的稳定性、低电阻和高透明度，并且适用于高度柔性的电子应用，包括触摸板、太阳能电池和OLED。
Here, we report highly transparent and flexible AgNW/SWCNT hybrid networks on PET substrates combined with plasmonic welding for securing ultrahigh stability in mechanical and electrical properties under severe bending. Plasmonic welding produces local heating and welding at the junction of AgNWs and leads strong adhesion between AgNW and SWCNT as well as between hybrid structure and substrate. The initial sheet resistance of plasmon treated AgNW/SWCNT hybrid film was 26 Omega sq(-1), with >90% optical transmittance over the wavelength range 400-2700 nm. Following 200 cycles of convex/concave bending with a bending radius of S mm, the sheet resistance changed from 26 to 29 Omega sq(-1). This hybrid structure combined with the plasmonic welding process provided excellent stability, low resistance, and high transparency, and is suitable for highly flexible electronics applications, including touch panels, solar cells, and OLEDs.
