  • Publication number: 20090318043
    Abstract: The invention concerns a method for making polymeric extruded composite products and carbon nanotubes. Said method includes the following steps: a) performing an oxidation pretreatment of the carbon nanotubes; b) dispersing the nanotubes in a polymer solution; c) extruding the resulting dispersion into an intermediate product; d) drying said intermediate product; e) post-treating said dried intermediate product by hot drawing process; f) post-treating said dried intermediate product of said drawn intermediate product by drawing in an ionic solution; g) performing a formalizing treatment process: Steps e) f) and g) are optional. The extruded polymeric products obtained by the inventive method can contain up to 80 wt. % of nanotubes.

  • Publication number: 20080275375
    Abstract: The invention relates to a block copolymer which is produced by a controlled radical polymerization, has an individual composition and structure and is used for adhesion in a humid medium The inventive copolymer comprises a continuous flexible and water repellent matrix (of elastomer nature) and a dispersed phase in the form of hydrophilic nanodomains. Said copolymer exhibits an excellent adhesion as a result of the structure thereof also in a very humid medium.

  • Publication number: 20060052545
    Abstract: The invention relates to a block copolymer which is produced by a controlled radical polymerisation, has an individual composition and structure and is used for adhesion in a humid medium. The inventive copolymer comprises a continuous flexible and water repellent matrix (of elastomer nature) and a dispersed phase in the form of hydrophilic mechanisms. Said copolymer exhibits and excellent adhesion as a result of the structure thereof also is a very humid medium.
