摘要:
Disclosed is a carbon nano-tube dispersant comprising a highly branched polymer having a repeating unit represented by, for example, formula (12) or (13), wherein the highly branched polymer is produced by the polycondensation of a triarylamine compound and an aldehyde compound and/or a ketone compound in the presence of an acid catalyst. The carbon nano-tube dispersant enables the dispersion of CNTs in a medium such as an organic solvent until the CNTs are so decomposed as to have an individual size. (In the formula, Z1 and Z2 independently represent a hydrogen atom, a phenyl group, a thienyl group, or the like.)

摘要:
A conductive composition containing carbon nanotubes, a carbon nanotube dispersant, and a dopant precursor, wherein the dispersant is a non-conjugated polymer compound having an aromatic ring as the repeating unit, and the dopant precursor is an acid-generating agent which generates cation by being subjected to light and/or heat. The aforementioned conductive composition is capable of stably dispersing carbon nanotubes and of efficiently doping same without damaging the conductive properties of the carbon nanotubes.

A method for producing a phenylphosphonic acid metal salt, including reacting a phenylphosphonic acid compound (a) with a metal salt, metal oxide or metal hydroxide (b) that is present in an amount beyond the equivalent; a phenylphosphonic acid metal salt composition comprising a phenylphosphonic acid metal salt and surplus metal salt, surplus metal oxide or surplus metal hydroxide produced by the method; and a thermoplastic resin composition comprising the phenylphosphonic acid metal salt composition.
摘要:
Chemically modified carbon nanotubes composed of carbon nanotubes (such as multiwall carbon nanotubes) having carboxyl groups on the surface thereof and polymeric aniline (such as 3- to 300-meric aniline) bonding thereto through the amide linkage. The chemically modified carbon nanotubes exhibit good affinity with organic solvents and readily disperse into organic solvents.

A surfactant comprising: a sulfate compound of Formula (1): R1—OSO3M (1) (where R1 is a C6-30 hydrocarbon group having a branched chain; and M is a hydrogen atom, an alkali metal, ammonium, a basic amino acid residue, an alkanolamine residue having a C2-3 hydroxyalkyl group, or an aliphatic alkanolammonium) for stabilizing a water/supercritical carbon dioxide microemulsion.
摘要:
A surfactant for water/supercritical carbon dioxide microemulsions that can achieve high water dispersion ability, water/supercritical carbon dioxide microemulsion forming ability under a moderate condition, and high water solubilization rate and that reduces burden on the environment and ecosystem. Provided are a surfactant for stabilizing a water/supercritical carbon dioxide microemulsion including a compound of Formula (I) and a water/supercritical carbon dioxide microemulsion including the surfactant. The compound of Formula (I) has the structure:

摘要:
A hyperbranched polymer containing, for example, a triarylamine structure represented by the formulae (10) to (13) below as a repeating unit, and having a weight average molecular weight of 750 to 4,000,000 is excellent in dissolving ability to carbon nanotubes. Consequently, by using such a hyperbranched polymer as a solubilizer, there can be obtained a composition wherein isolated carbon nanotubes are dissolved.
