    摘要: Humidity adjusting films are sandwiched between the catalyst electrode layers and carbon fiber collector layers of a solid polymer type fuel cell. These humidity adjusting films are constructed from a conductive carbonaceous powder and a polytetrafluoroethylene. The moisture permeability as measured by the method stipulated in JIS L 1099 (B-1) is 1200 to 4000 g/m2 hr, and the mean thickness of the films is 5 to 100 μm.

    摘要: A colored, porous fluorocarbon material is provided wherein a porous layer of a colored dyeing-site resin is formed on all surfaces of the fluorocarbon material. This new material is made by a process whereby an auxiliary solvent which does not readily dissolve a dyeing-site resin, if at all, is added to a solution of the dyeing-site resin in a main solvent, and this is coated onto the surfaces of the fluorocarbon material and dried. The material may be dyed by adding dyestuff to the aforesaid solution or it may be dyed after coating and drying. The coated fluorocarbon material can be stretched.

    摘要: A sensor for measuring concentrate of solute in an aqueous solution in which a humidity sensor is enclosed and sealed within a porous fluorine polymer film that is liquid water impermeable but water vapor permeable. The sensor operates by measuring water vapor pressure in the gaseous phase inside the sealed film after the inside and outside have equilibrated with respect to water outside and inside.

    摘要: A water-vapor-permeable, waterproof, highly elastic film of expanded, porous, unsintered polytetrafluoroethylene having impregnated within the pores of the porous film, on both sides thereof, a water-vapor-permeable resin, for example, an elastomer containing urethane bonds and a hydrophilic group(s) in its molecular structure. The film of this invention is useful in clothing, tents, and various applications where water vapor transmission characteristics and waterproofness are simultaneously desired. The film has elongation percentage in at least one direction exceeding 40% and durability in repeated stretching to 80% of its elongation percentage of more than 200,000 cycles.
