Supramolecular Chemistry

The 1st NATO technology discussion board used to be held in Biarritz in September 1990. This Taormina convention is the second one in a chain that we want to be an extended one and that i think that it has equalled the luck of its predecessor. In developing those conferences the NATO technology Committee desired to assemble top specialists to study fields of sturdy current curiosity.

20b showed the structure of EDL which is filled with positive charge on the surface of porous electrode (Stern model, ignoring the curvature of hole). The negative charges on both Stern layer and diffusion layer contribute to EDL. 3) 30 1 Literature Review and Research Background Fig. 20 Schematic diagrams of a a two-cell supercapacitor device made of nonporous electrode and b the EDL structure based at a positively charged electrode surface. Reproduced from Ref. [110] by permission of The Royal Society of Chemistry where ɛr (dimensionless constant) is the relative permittivity, ɛ0 (F g−1) is the permittivity of free space, A (m2 g−1) is the specific surface area of electrode by the electrolyte accessibility, d (m) is the effective thickness of EDL (also known as the Debye length).

This shows that the quality of bottom carrier and the structure design of nanoparticles are critical to the performance of supercapacitors. ZnO and SnO2 modified graphene also has been reported, but the corresponding capacitance is unsatisfactory, which is around 62 F g−1 [126]. Graphene/polymer nanocomposites have a great potential in supercapacitor. Polyaniline/graphene-based nanomaterial can be easily prepared by electrochemical and chemical methods (Fig.

Graphene/polymer nanocomposites have a great potential in supercapacitor. Polyaniline/graphene-based nanomaterial can be easily prepared by electrochemical and chemical methods (Fig. 22). The capacitance ranged from 233 to 1046 F g−1 based on different composite nanostructure [127–131].
