我们最近在Advanced Functional Materials上发表一篇关于graphene-polymer nanocomposite的工作。该工作通过官能化graphene来调节其光学尤其是非线性光学性能，采用静电纺丝技术制备出polymer membrane，这种自支持的薄膜用于做饱和吸收体在光纤激光器中产生超快激光，尤为重要的是可以输出宽波段可调脉冲。该工作首次采用化学材料设计以及半工业化工艺证实了graphene-polymer composite在超快光电子方面的一种极具前景的应用。该文摘要如下：

A freestanding membrane composed of a nanofiber network of a graphene–polymer nanocomposite is fabricated by electrospinning and applied as an optical element in fiber lasers. The functionalization of graphene with conjugated organic molecules provides a handle for improving mechanical and thermal properties as well as tuning the optical properties. A small loading (0.07 wt%) of functionalized graphene enhances the total optical absorption of poly(vinyl acetate) (PVAc) by 10 times. The electrospun graphene–polymer nanocomposites exhibit wideband saturable absorbance for laser pulse shaping, and attain a larger modulation depth and smaller nonsaturable loss than single-walled carbon nanotubes. The results show that electrospun graphene nanocomposites are promising candidates as practical and ef?cient photonic materials for the generation of ultrashort pulses in fiber lasers.
