A novel roll-to-roll, etching-free, clean transfer of CVD-grown graphene from copper to plastic using surface-energy-assisted delamination in hot deionized water is reported. The delamination process is realized by water penetration between the hydrophobic graphene and a hydrophilic native oxide layer on a copper foil.The transferred graphene on plastic is used as a high-output flexible and transparent triboelectric nanogenerator.
本文报道了一种新颖的卷对卷、无刻蚀、清洁的方法，即在热去离子水中利用表面能辅助的分层作用，将 CVD 生长的石墨烯从铜转移到塑料上。分层过程是通过疏水石墨烯和铜箔上亲水本征氧化层之间的水渗透实现的。转移到塑料上的石墨烯可用作高输出的柔性透明摩擦电纳米发电机。
