We used AuNPs prepared using the GO sheet method to modify the AuNP-GO nanocomposite.

It is found that the size of gas molecule and its interaction with GO sheet are two key factors in determining the diffusivity in interlayer gallery of GO, which results in significant difference of selectivity and permeability for H2 and CH4.
For GO-GnP hybrid configuration, it was shown that GnP particles were mostly anchored onto GO sheet which was mostly attributed to the electrostatic and hydrophobic interaction between the particles.
In addition, as for the film from DA subphase with UV light, the nanostructures become cluttered in three dimensional modes and some strip-like aggregates appear on GO sheet (Fig. 3c), suggesting the interfacial thiol-ene photopolymerization between thiol groups in GO-SH and DA molecules.
AFM image of GO showed that the GO sheet is flat and smooth, and the height of GO sheet is about 1 nm, indicating the mono-layer GO sheet was successfully prepared.
The arrows clearly show the edges of the GO sheet.
FESEM images illustrated that the spread single GO sheet embedding into nanofibers was formed via self-assembly of GO sheet and PVA/CS chains.
The lateral size of a GO sheet ranges from several hundred nanometers to several micrometers.
The hydrophilic treatment of the Si surface promotes GO sheet deposition on Si.
Each single GO sheet might be approximately 1 nm thick as described in [12].
