Abstract:
The present invention relates to hydrophobic powder particles or fibers for removing oil and organic materials which selectively absorb oil and organic materials on the surfaces of powder particles and fibers which are coated with silicon-carbon complexes and are manufactured by a method comprising: a step (step 1) of locating power particles and fibers on the lower part of a reactive container, arranges silicon organic polymers in the upper part in order not to be contacted with the power particles and fiber and performing heating; and a step (step 2) of forming a film by depositing gas phase silicon organic polymers by heating on the powder particles or fibers. The hydrophobic powder particles or fibers coated with silicon-carbon complexes for removing oil and organic materials are able to selectively oil and organic materials on an aqueous solution, do not react with water and are able to selectively remove organic pollutants in sea water, river and the like. The present invention is able to easily remove powder particles absorbing organic materials by using outer magnetic fields when powder particles for removing organic materials are manufactured with powder particles having magnetism.

The heating is performed at 150-300 deg. C.
Abstract:
The present invention relates to a method for preparing a carbon filter having porous nickel deposited thereon by depositing nickel on the surface of carbon fibers via an electroless nickel plating method and forming pores on the surface via thermal treatment at a temperature ranging from 300°C to 800°C. The method for preparing a carbon filter having porous nickel deposited thereon according to the present invention enables a user to simply form nickel nanopores via electroless plating and thermal treatment at a temperature ranging from 300°C to 800°C. Accordingly the preparing method is simpler and economical. Also the carbon filter can be used as a catalyst for adsorbing the particles of foreign materials because the size and distribution of the pores can be controlled by simple temperature adjustment. Also the carbon filter can be used as a medium for depositing metal or a metal oxide because the metal and the metal oxide can be supported on the carbon filter having porous nickel deposited thereon.
