Nanocarbon-based conducting fibres have been produced using solution- or dry-spinning techniques. Highly conductive polymer-composite fibres containing large amounts of conducting nanomaterials have not been produced without dispersants, however, because of the severe aggregation of conducting materials in high-concentration colloidal solutions. Here we show that highly conductive (electrical c...
Solvent relaxation NMR has been used to estimate the surface areas and wettability of various types of nanostructured carbon materials in a range of solvents including water, ethanol, and tetrahydrofuran. We illustrate the application of the technique through several short case studies using samples including nanocarbon blacks, graphene oxide, nanographites, and porous graphenes. The technique ...
Strain sensors capable of operating in high strain conditions remain a technical challenge. In particular, biocompatible strain sensor technology is needed that satisfies the following requirements: (1) construction from low modulus materials that approach values of soft biological tissues and (2) high strain operation (≥ 20%). We present a screen printed, nanocomposite-based conductive polydim...
The planar trigonal structure of 1,3,5-trisubstituted benzene, named phenine, has been adopted as basic units polygonal networks to shape nanometer-sized curved organic π-molecules. phenine design allows for concise syntheses large carbonaceous molecules reaching 4 kDa by stitching geodesic lines with aryl coupling reactions. In this Account, the development defective nanocarbon molecules, i.e....
