It is an object of the present invention to provide a coating film capable of realizing satisfactory sliding properties in addition to water- and oil-repellent properties and wear resistance evaluated by a static contact angle, and a coating composition for obtaining the coating film. The present invention is directed to a fluorine-containing coating film which has a root mean square roughness of less than 3.5 nm and has a perfluoropolyether structure. It is preferred that the coating film has a polysiloxane backbone and further has a structure in which a fluoroalkyl group is directly bonded to a silicon atom of the polysiloxane backbone, and that a sliding angle of 6 &#x3bc;L of a water droplet is 24.3&#xb0; or less, or a speed of 20 &#x3bc;L of a water droplet sliding on a coating film inclined at 32&#xb0; is 0.1 cm/second or more.

Disclosed is a sodium secondary battery. The sodium secondary battery comprises a first electrode and a second electrode comprising a carbonaceous material. The carbonaceous material satisfies one or more requirements selected from the group consisting of requirements 1, 2, 3 and 4. Requirement 1: R value (=ID/IG) obtained by Raman spectroscopic measurement is 1.07 to 3. Requirement 2: A value and &#x3c3;value obtained by small angle X-ray scattering measurement are &#x2212;0.5 to 0 and 0 to 0.010, respectively. Requirement 3: for an electrode comprising an electrode mixture obtained by mixing 85 parts by weight of the carbonaceous material with 15 parts by weight of poly(vinylidene fluoride), the carbonaceous material in the electrode after being doped and dedoped with sodium ions is substantially free from pores having a size of not less than 10 nm. Requirement 4: Qvalue obtained by a calorimetric differential thermal analysis is not more than 800 joules/g.

An oxygen-absorbing material including a transition metal compound and one or more thermoplastic resins, when used for a molded product such as container, exhibits excellent gas-barrier and oxygen-absorbing properties. The material absorbs oxygen from contents and blocks oxygen from entering so that the contents can be maintained in an oxygen-free state for a long period of time. An excellent oxygen-absorbing property is achieved by an amino group content of 20 mmol/kg or lower in at least one thermoplastic resin and by lowering the crystallinity of the thermoplastic resin.
