主　　题：Composite membrane Reduced graphene oxide:Carbon fiber Self-floating Solar steam generation 

摘      要：Solar-thermal water evaporation has attracted increasing attention owing to the promising potential to solve the global clean water and energy ***,the development of this strategy is limited by the lack of materials with high solar-thernal conversion efficiency,local heating of superficial water,easy preparation and low ***,we proposed a facile strategy to prepare a reduced graphene oxide/carbon fiber composite membrane,denoted as RGO/CF *** surface of the RGO/CF membrane was highly hydrophobic,endowing the composite membrane with the self-floating ability on the water without any *** light absorbance ability achieved as high as ca.98%in the wavelength range of 300-1200 *** steam evaporation efliciency under the illumination of3-sun was 97%,generating water steam at a rate of 4.54 kg·m^-2·h^-***,the solar-thermal steam production rate showed high stability during successive 30 cvcle tests.
