Method and apparatus for identifying and characterizing material solvents and composite matrices and methods of using same

摘要

Solvents for macromolecules generally believed to be insoluble in their pristine form are identified by generation of a “solvent resonance” in the relationship between solvent quality (deduced by Rayleigh scattering) and an intrinsic property of solvents. A local extreme of the solvent resonance identifies the ideal intrinsic property of an ideal solvent which may then be used to select a particular solvent or solvent combination. A solvent for graphene is used in the production of transparent conductive electrodes.

1. A method of preparing a polymer composite comprising the steps of:
(a) placing bulk, non-functionalized graphite in a solvent; (b) exfoliating graphene sheets directly from the non-functionalized graphite placed in the solvent as a result of the interaction of the non-functionalized graphite with the solvent; (c) dispersing the graphene sheets exfoliated directly from the bulk, non-functionalized graphite in the solvent, wherein the solvent is characterized by a value of chi less than about 0.08; and (d) capturing the dispersed graphene sheets in a substantially solid phase polymer matrix.
