  • Patent number: 9403960
    Abstract: The invention relates to fluoropolymer articles that have been irradiated with at least 5 Kilo Gray of radiation, where the resulting articles have low levels of leachable or extractable fluoride ion. The low fluoride ion migration from the irradiated article is due to the presence of low levels of metallic salts or oxides in the fluoropolymer composition. The invention is especially useful for fluoropolymer articles in which the fluoropolymer layer contacts a biological or pharmaceutical fluid, and that are subjected to sterilization by irradiation.

  • Patent number: 9284398
    Abstract: Modified carbon nanotubes are provided having carbon nanotube core covalently bound through C—C bonds to a polymer shell surrounding the carbon nanotube core. The polymer shell is a polymer having functional groups pointing outwardly from the shell. The functional groups are compatible with or able to covalently connect to another polymer. Such modified carbon nanotubes are more readily dispersed in a homogeneous manner in another polymer and may be used as a reinforcing filler in a polymer matrix. The modified carbon nanotubes with a core-shell structure in which the core has a substantially unidirectional orientation within the shell are produced by reacting neutral carbon nanotubes with 4-vinylaniline through a diazonium reaction in presence of one or more types of multifunctional monomers carrying a vinyl moiety and one or more functional groups for compatibilization with or connection to another polymer.

The surface enhancement comprises a self-healing coating based on crosslinkable fluoropolymers, e.g. PFEVE (polyfluoroethylene alkylvinyl ethers). These coatings exhibit good optical properties, can be used in outdoor applications, more particularly in solar applications, over very long periods of time, exhibit self-cleaning properties, and in particular are self-healing in relation to mechanical damage—such as scratching.

  • Patent number: 8632856
    Abstract: Highly water repellent coated articles may be made by applying to a substrate a coating having dispersed therein or sprinkled thereon partially or fully fluorinated polymer microparticles. The coating includes a partially fluorinated hexafluoropropylene copolymer binder in a nonfluorinated solvent that dissolves the binder and does not dissolve the microparticles. The coating is heated sufficiently to bond the microparticles to the binder but not so much as to cause the receding water contact angle for the coating to fall below 80°.

  • Publication number: 20140011947
    Abstract: An environmentally friendly backsheet for a solar cell, a method of manufacturing the same, and a photoelectric cell module are provided. The backsheet for a solar cell is manufactured by preparing an aqueous dispersion composition by dispersing a fluorine-based polymer in water, applying the aqueous dispersion composition to a substrate, and melting the aqueous dispersion composition. Therefore, compared to the conventional art using an organic solvent, an increase in production cost may be prevented, and the backsheet is environmentally friendly since an organic solvent having high toxicity is not used. In addition, the backsheet has better physical properties such as adhesive strength and color change stability under the extreme conditions (high temperature and humidity), compared to a backsheet for a solar cell commercially available in the current market.
