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.

External link. However, with the intercalation of more water molecules, the inter-flake distance finally expands over the value of cut-off distance r cand the hydrogen bond formed between intercalated water molecules and their adjacent GO flakes becomes the major interaction forces.

Additionally, a hysteresis loop is associated with the secondary pore filling Exposing the GO samples to water vapor results in a shift in the. a remote sensing that measures vertical profiles of water-vapor mixing ratio and The intrinsic noise is diminished, e.g., either by using a feedback loop as in a.
Therefore, after heating to drive the collected moisture exhausted, GO desiccant can be reused. High-yield production of graphene by liquid-phase exfoliation of graphite.
Water science and technology: a journal of the International Association on Water Pollution Research. S6 Therefore, it is evident that GO has significant potential in inhibiting fungal and bacterial propagation in food by absorbing moisture from the environment. We measured the permeation rate as shown in Fig.
Thermal performance of miniature loop heat pipe with graphene–water nanofluid The difference in diameter prevents reverse flow of vapour through liquid line.
Moscou, R A. Exposing the GO samples to water vapor results in a shift in the reflection, which corresponds to an increase in the interlayer distance.
Graphene oxide papers with high water adsorption capacity for air dehumidification
Phys Rev Lett 91 To gain insight into water permeation through subnm-wide capillaries, we employed a model as shown in Fig. Water adsorption in MOFs: fundamentals and applications.
Astrum Recommended for you. Thus, rGO shows a different water adsorption tendency from GO.

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.
