A composite coating of N-doped graphene quantum dots (N-GQDs)/polymethyltrimethoxysilane (PMTMS) is prepared on the surface of AZ91D magnesium alloy via electrodeposition and subsequent silane treatment. The microstructure of the N-GQDs/PMTMS composite coating is characterized by field emission scanning electron microscopy (FE-SEM), energy dispersive X-ray spectroscopy (EDS), transmission electron...
A blister test and associated analysis was developed to characterize the interfacial adhesion between graphene and substrates to which it has been transferred. In this study, chemical vapor deposition grown graphene had been transferred to a highly polished copper substrate from its seed foil. The graphene/photoresist composite film was pressurized with deionized water through a nominally 1-mm hole...
Dynamic thermal degradation of amorphous carbon nitride (a-CN x ) thin films was studied in N 2 and air. The films were magnetron-sputtered at two different pressures to yield various C–C and C–N ratios. Typically, the films consist of interstitial and weakly-bonded carbon–nitrogen molecules or clusters and nitrogen-substituted graphitic-carbons. The carbon and nitrogen atoms are mainly...
