Abstract In this article, we determine the impact of laser parameters on the development of a flexible conductive transparent film in multi wall carbon nanotubes (MWCNTs) regular structures fabricated on the PET substrate. Both MWCNT and PET are the attractive material for flexible electronics and technological interest in Micro/Nano-manufacturing. Now day, femtosecond laser irradiation nanojoining with selected surface treatments is introduced as an interface enhancer between MWCNT and the PET. We investigated the femtosecond laser of fused PET. After laser irradiation heating, thermal effects modify the structures, and the properties of MWCNTs at the junction point. The network created by Laser irradiation requires extreme parameters: Laser energy irradiation, the effective laser radius, and preheating temperature. Theoretical calculations show us that 90 mW under laser spot radius of 1.5 mm and preheating temperature of 300 K can generate 433.0845 K as surface temperature enough to connect 1 µm in thick of MWCNTs without damage the PET substrate.

PET基板上多​​壁碳纳米管规则结构飞秒激光焊接互连的温度监测

摘要 在本文中，我们确定了激光参数对在 PET 基板上制造的多壁碳纳米管 (MWCNT) 规则结构中柔性导电透明薄膜的发展的影响。MWCNT 和 PET 都是对柔性电子产品和微/纳米制造技术感兴趣的有吸引力的材料。现在，飞秒激光辐照纳米接合与选定的表面处理被引入作为 MWCNT 和 PET 之间的界面增强剂。我们研究了熔融 PET 的飞秒激光。激光辐射加热后，热效应改变了结点处多壁碳纳米管的结构和特性。激光照射创建的网络需要极端参数：激光能量照射、有效激光半径和预热温度。
