Abstract

The rapid development of industrialization also brings a variety of pollution to the ecological environment, advanced materials play a more and more important role in the control or removal of these pollutants. In 2012, we first reported that graphene sponge can be used for the efficient and recyclable adsorption materials for oils and commonly used organic solvents. Then, constantly optimizing the adsorption properties, adsorption capacity can be increased to its own weight more than 800 times; the pore size of graphene sponges from 10 to 800um and pore wall thickness from 20 nm to 80 um are continuously adjustable by optimization of structure and preparation method; further, in order to reduce the cost, cotton and waste paper are selected to use as raw materials to prepare carbon sponge as the adsorption materials with low price; in order to remove the trace oil, graphene based functional papers are designed and prepared. In addition to the structure of graphene sponge, another two kinds of structures are developed, one is graphene based metal net, which can be integrated in the filtering system to realize three-phase separation of water, oil and suspended solid particles; another is graphene-based flexible filtering film, which is used for the production of PM2.5 filter masks and expected to enter the market within half a year.
