▎ 摘 要
Graphene oxide-based composite (SSGO) with orderly pores was prepared by freeze-drying method. Its chemical structure, morphology and mechanical property were investigated. The results show that it has a unidirectional microporous structure which facilitates the diffusion of dyes. The incorporation of GO significantly improves the porous structure, and increases the compressive strength of SSGO. A 26.6 kPa increase and a 3 kPa improvement of strength in dry and wet states were achieved when 4wt% GO was added. Moreover, the equilibrated adsorption capacity for methylene blue (MB) increased about 78.9%, up to 161 mg/g. With superior compressive strength and excellent adsorption capacity, the SSGO has promising recyclable application in dyes removal from wastewater. (C) 2015 The Japan Society of Applied Physics
