METHOD OF PREPARING FULLEREN-CONTAINING MATERIAL Russian patent published in 2004 - IPC

FIELD: carbon materials. SUBSTANCE: fulleren mixture consisting of C60, C70, and C84 fullerens at their weight ratio 10:2:0.1 is first provided, to which pyrocarbon is added at fulleren mixture-to-pyrocarbon weight ratio (1-5): (1-10) and the total is stirred until homogenous fulleren/pyrocarbon composition is obtained. The latter is then supplemented by quartz filler, in particular quartz sand fraction 0.1-1.0 mm combined with quartz powder having particle size 0.001- 0.1 mm at their weight ratio between 1:1 and 1: 5, weight ratio of fulleren/pyrocarbon composition to quartz filler being between 1: 10 and 1:20. Resultant blend is homogenized by stirring and deposited by means of slotted nozzle onto substrate: polyamideimide film 0.1-1.0 mm thick in the form of layer with thickness 0.2-2.0 mm. Film surface is simultaneously heated to 200-220 C and further covered by the same film. Layered material thus obtained is rolled between rolls producing pressure 0.2-0.5 kg/sq.cm while being simultaneously heated to 200-250 C. Resulting elastic fulleren-containing material is perforated on both sides with the aid of needles to a depth constituting 1.1 film thickness. Perforations are made in such a manner as to prevent formation of through holes and coincidence of perforations from opposite sides of material. The two sides are then coated with protective film or waxed paper. Several layer of such material may be thus prepared, outside polyamideimide films being strengthened with reinforcing grid. Invention product can be used for treatment and separation of hydrocarbon fluids, aqueous solutions, and suspensions. EFFECT: enhanced efficiency of cleaning hydrocarbon-containing fluids. 3 cl
