  • Patent number: 9410245
    Abstract: A gas barrier plastic molded product having high gas barrier properties is provided. The gas barrier plastic molded product is a gas barrier plastic molded product comprising a plastic molded product and a gas barrier thin film provided on the surface of the plastic molded product, in which the gas barrier thin film contains silicon (Si), carbon (C), oxygen (O) and hydrogen (H) as constituent elements, and comprises a Si-containing layer having a Si content percentage represented by (Mathematical Formula 1) of 40.1% or more: Si content percentage [%]={(Si content [atomic %])/ (total content of Si, O and C [atomic %])}×100??(Mathematical Formula 1) wherein in Mathematical Formula 1, the content of Si, O or C is a content thereof in the items of the three elements of Si, O and C.

  • Patent number: 7597868
    Abstract: Powdery fullerene is milled in an oxygen atmosphere, whereby mechanical impacts are applied to the fullerene and a carbon cage of the fullerene is dynamically distorted to the extent that an energy for conversion of atmospheric oxygen to a singlet excited state is accomplished from the distorted carbon cage to atmospheric oxygen. Singlet oxygen, i.e. an efficient oxidant in various industrial fields, is generated by solid-state reaction under stable conditions without necessity of photo-irradiation. The singlet oxygen also enables efficient oxidation of fullerene itself.
