Electrospinning is a versatile method for forming continuous thin fibers based on an electrohydrodynamic process. This method has the following advantages: (i) the ability to produce thin fibers with diameters in the micrometer and nanometer ranges; (ii) one-step forming of the two- or three-dimensional nanofiber network assemblies (nanofibrous membranes); and (iii) applicability for a broad spectrum of molecules, such as synthetic and biological polymers and polymerless sol-gel systems. Electro
The graphene nanoribbon (GNR)/carbon composite nanofiber yarns were prepared by electrospinning from poly(acrylonitrile) (PAN) containing graphene oxide nanoribbons (GONRs), and successive twisting and carbonization. The electrospinning process can exert directional shear force coupling with the external electric field to the flow of the spinning solution. During electrospinning, the well-dispersed GONRs were highly oriented along the fiber axis in an electrified thin liquid jet. The addition of
Proton and potassium ions countertransport across perfluorocarbon-type (Nafion) and hydrocarbon-type (K-101) cation-exchange membranes was studied, and the effect of proton transport on potassium ion transport was examined. It is considered that the fixed charge groups are distributed heterogeneously in the former and homogeneously in the latter. The experimental results were compared with calculated values using the Teorell−Meyer−Sievers's theory, which formulated transport phenomena based on t
