Plasma treatment for enhanced functionalization of graphene nanosheets by octadecylamine

Mussel-inspired functionalization of graphene for synthesizing Ag-polydopamine-graphene nanosheets as antibacterial materials.

Mussels have been shown to attach to virtually all types of inorganic and organic surfaces via their adhesive proteins. The adhesive proteins secreted by mussels contain high concentrations of catechol and amine functional groups, which have similar functional groups with polydopamine (PDA). Inspired by mussels, a mild and environmentally friendly method was used to synthesize Ag nanoparticles ...

Surface Functionalization of Graphene with Polymers for Enhanced Properties

Thinning and functionalization of few-layer graphene sheets by CF4 plasma treatment

Structural changes of few-layer graphene sheets induced by CF4 plasma treatment are studied by optical microscopy and Raman spectroscopy, together with theoretical simulation. Experimental results suggest a thickness reduction of few-layer graphene sheets subjected to prolonged CF4 plasma treatment while plasma treatment with short time only leads to fluorine functionalization on the surface la...

SYNTHESIS AND FUNCTIONALIZATION OF ATOMIC LAYER BORON NITRIDE NANOSHEETS FOR ADVANCED MATERIAL APPLICATIONS Besides graphene, hexagonal boron nitride nanosheets

SYNTHESIS AND FUNCTIONALIZATION OF ATOMIC LAYER BORON NITRIDE NANOSHEETS FOR ADVANCED MATERIAL APPLICATIONS Report Title Besides graphene, hexagonal boron nitride nanosheets (BNNSs) are playing an excellent role for the next generation of 2-dimentional (2D) functional nanomaterials. Due to the similar lattice parameter and identical crystalline structure to that of graphene, BNNSs are often kno...

Enhanced thermopower of graphene films with oxygen plasma treatment.

In this work, we show that the maximum thermopower of few layers graphene (FLG) films could be greatly enhanced up to ∼700 μV/K after oxygen plasma treatment. The electrical conductivities of these plasma treated FLG films remain high, for example, ∼10(4) S/m, which results in power factors as high as ∼4.5 × 10(-3) W K(-2) m(-1). In comparison, the pristine FLG films show a maximum thermopower ...
