Abstract

We employ H₂/Ar low-damage plasma treatment (H₂/Ar-LDPT) to reduce graphene oxide (GO) coating on a polymer substrate-polyethylene terephthalate (PET)-with the assistance of atomic hydrogen (H) at low temperature of 70 °C. Four-point probing and ultraviolet-visible (UV-Vis) spectroscopy demonstrate that the conductivity and transmittance can be controlled by varying the H₂/Ar flow rate, treatment time, and radio-frequency (RF) power. Optical emission spectroscopy reveals that the H intensity depends on these processing parameters, which influence the removal of oxidative functional groups (confirmed via X-ray photoelectron spectroscopy) to yield reduced GO (rGO). To further improve the conductivity while maintaining high transmittance, we introduce silver nanowires (AgNWs) between rGO and a PET substrate to obtain a hybrid rGO/AgNWs/PET with a sheet resistance of ~100 Ω/sq and 81% transmittance. In addition, the hybrid rGO/AgNWs thin film also shows high flexibility and durability and is suitable for flexible and wearable electronics applications.

摘要

我们采用H₂/Ar低损伤等离子体处理(H₂/Ar-LDPT),在70°C的低温下借助原子氢(H)来减少聚合物基底聚对苯二甲酸乙二酯(PET)上的氧化石墨烯(GO)涂层。四点探针法和紫外可见(UV-Vis)光谱表明,通过改变H₂/Ar流速、处理时间和射频(RF)功率,可以控制导电性和透光率。光发射光谱显示,H强度取决于这些工艺参数,这些参数会影响氧化官能团的去除(通过X射线光电子能谱确认),从而生成还原氧化石墨烯(rGO)。为了在保持高透光率的同时进一步提高导电性,我们在rGO和PET基底之间引入银纳米线(AgNWs),以获得方阻约为100Ω/sq且透光率为81%的rGO/AgNWs/PET复合材料。此外,rGO/AgNWs混合薄膜还具有高柔韧性和耐久性,适用于柔性和可穿戴电子应用。
