  • Publication number: 20140275342
    Abstract: Advanced epoxy resins comprising the reaction product of an epoxy resin comprising a diglycidyl ether of Formula 1 as defined herein, and at least on difunctional compound selected from an aromatic diol and a dicarboxylic acid are described. The diglycidyl ether contains a cycloaliphatic ring of 3-5 carbon atoms. Purified diglycidyl ether is used to obtain substantially linear, high molecular weight, advanced epoxy resin. Curable compositions, cured compositions, and articles comprising the advanced epoxy resins are also disclosed. The advanced epoxy resins provide cured coatings having improved flexibility and low total chlorine content.

  • Publication number: 20050181143
    Abstract: The control method of arranging carbon nanotubes selectively orientationally on the surface of a substrate relates to the field of nano-technology. The invention includes: a) treating the solid substrate to be hydrophilic or hydrophobic; b) attaching the organic macromolecular with hydrophilic and hydrophobic end to the surface of the purified carbon nanotubes, and dissolving those carbon nanotubes into water or a solvent; c) spreading the above solution onto the surface of water in sub-phase by controlling the surface pressure-area isotherm of the carbon nanotube film on the water surface after volatilization of water or the organic solvent; d) transferring the formed carbon nanotube film to the above treated solid substrate surface to form the arrangement layer of the carbon nanotubes. This invention possesses substantial characteristics and notable improvement. The present invention can control the arrangement direction of the carbon nanotubes and can successively remove organic molecule.
