  • Super-hydrophobic fluorine containing aerogels
    Patent number: 7211605
    Abstract: An aerogel material with surfaces containing fluorine atoms which exhibits exceptional hydrophobicity, or the ability to repel liquid water. Hydrophobic aerogels are efficient absorbers of solvents from water. Solvents miscible with water are separated from it because the solvents are more volatile than water and they enter the porous aerogel as a vapor across the liquid water/solid interface. Solvents that are immisicble with water are separated from it by selectively wetting the aerogel. The hydrophobic property is achieved by formulating the aerogel using fluorine containing molecules either directly by addition in the sol-gel process, or by treating a standard dried aerogel using the vapor of fluorine containing molecules.

    Abstract: The present invention relates to absorbent cores for absorbent articles, which are intended to receive and retain bodily discharges such as urine. Such articles are disposable hygiene articles like baby diapers, training pants, adult incontinence articles, feminine care articles and the like. The improvement essentially is based on the recognition that replacing most or all of the cushioning fibrous absorbent material in an absorbent core by a liquid storage material capable of retaining liquid while maintaining or improving acquisition behavior is desirable as the reduction in cushioning is more than compensated by the gain in comfort. The comfort however can only be achieved if the more fundamental requirements of a diaper in respect to liquid handling are satisfied or improved.

The toner is unlikely to cause degeneration or scratching of organic photoreceptors, displays excellent dispersibility and favorable flowability and consequently does not cause adhesion to the photoreceptor.

  • External additive for electrostatically charged image developing toner
    Patent number: 7083888
    Abstract: An external additive for electrostatically charged image developing toner is provided. The additive includes spherical hydrophobic fine silica particles having primary particles with a particle diameter of from 0.01 to 5 ?m and having been treated with a compound selected from the group consisting of a quaternary ammonium salt compound, a fluoroalkyl-group- or fluoroalkenyl-group- containing betaine compound and a silicone oil. The fine silica particles fulfill conditions (i) and (ii), as described in the disclosure. The external additive does not react or has no interaction with an organic photoreceptor and therefore change in quality does not occur or the photoreceptor is not scraped. Furthermore, it has a good flowability and therefore adhesion of a toner to the photoreceptor does not occur.
