The adsorbing capacity of the PGO-CS is 1.47 × 103 mg g−1 and it was found that a higher pH and a higher ionic strength improve the adsorption. In contrast to other books on composites, this work emphasizes materials rather than mechanics. This emphasis reflects the key role of materials science and engineering in the development of composite materials. The development of an effective method for detecting heavy-metal ions remains a serious task because of their high toxicity to public health and environments. The chemical reduction method uses mainly mild reduction agents to restore the sp2 network but often leads to a small surface area since the graphene layers agglomerate through π–π interaction. Graphene aerogel takes lightest material crown – could be used to clean up oil spills. The
