Production of Few-Layer Graphene Through Liquid-Phase Pulsed Laser Exfoliation of Highly Ordered Pyrolytic Graphite
Graphene suspension was obtained through liquid-phase pulsed laser exfoliation of highly ordered pyrolytic graphite (HOPG). The liquid-phase pulsed laser process leaded to the compression and expansion of HOPG surface, resulting in the exfoliation of graphene sheets. Graphene sheets of âˆ¼1Â nm in thickness and micrometers in size were obtained. Transparent conductive graphene films were fabricated by vacuum filtration, showing an electrical conductivity of âˆ¼1000Â S/m and an optical transparency of âˆ¼75% at 550Â nm. This study demonstrated the growth of few-layer graphene by pulsed laser exfoliation of HOPG in liquid and explored its applications in transparent conductive films.
