Our results suggest that GO will find numerous practical applications as a desiccant and is a promising material for moisture desiccation and food preservation. The Royal Institution Recommended for you. ACS nano. Park S, et al. Nat Nanotechnol. The various aspects of graphene oxide paper have further been exploited, for example, in energy storage, gas sensor, molecular separation, piezoelectricity, supercapacitor, adsorption and so on, aiming to widen its application 7914 — Graphene-based composite materials. This is due to lack of holes, defects, functional groups on intrinsic graphite flakes compared with rGO. This video is unavailable.

    More Report Need to report the video? Based on this theory, we can speculate that unlike silica gel, the adsorption capacity of the two types of GO sharply increase at low partial pressure regions of water vapor because of the strong interaction between GO and water molecules Communication: Shifted forces in molecular dynamics.
