An oil-water separation apparatus is provided which can easily separate and collect oil from a liquid mixture containing water and oil at low cost. The oil-water separation apparatus includes an oil-water-separating member configured to separate a liquid mixture containing water and oil into moisture and oil, and a liquid reservoir subdivided into an upper region and a lower region by the oil-water-separating member. The oil-water separation apparatus filters the liquid mixture by gravity. The oil-water-separating member includes a base which includes a channel for the liquid mixture. The oil-water-separating member is formed in the base, and the oil-water-separating member contains a fluorine compound which has an oil-repellency-imparting group and a hydrophilicity-imparting group. A drain port for discharging the moisture is formed in the lower region of the liquid reservoir.

This carbon nanofiber is produced by a vapor phase reaction of a carbon oxide-containing raw material gas using a metal oxide powder including a Co oxide as a catalyst, wherein at least one type selected from metal cobalt, carbon-containing cobalt metals, and cobalt-carbon compounds is contained (encapsulated) in the fiber in a wrapped state. This method for producing a carbon nanofiber includes: producing a carbon nanofiber by a vapor phase reaction of a carbon oxide-containing raw material gas using a mixed powder of a Co oxide and a Mg oxide as a catalyst, wherein a mixed powder of CoO and MgO, which is obtained by hydrogen-reducing a mixed powder of CoOand MgO using a reduction gas having a hydrogen concentration in which metal cobalt is not generated, is used as the catalyst.

A hydrophilic collector for alkaline secondary batteries is formed of a nonwoven fabric plated with nickel in which the nonwoven fabric is hydrophilized by sulfonation, a gaseous fluorine treatment, or vinyl monomer grafting. A method for making the collector includes a hydrophilizing step of a nonwoven fabric comprising at least one of a polyolefin fiber and a polyamide fiber, and a plating step of applying nickel plating to the hydrophilic nonwoven fabric. Preferably, the nickel plating is electroless plating, and the nonwoven fabric has a plurality of micropores extending from one surface to the other surface thereof. An electroplating film may be deposited on the electroless plated film, if necessary. This collector facilitates assembling a battery which exhibits improved high-rate discharge characteristics due to improved adhesiveness of the plated nickel film to the nonwoven fabric.

A white conductive fiber is manufactured at an inexpensive cost having superior conductivity and high degree of whiteness, in which a metal coating plated on the fiber has superior adhesiveness. A method for manufacturing the white conductive fiber comprises the steps of mounting a wound fiber body formed by winding a continuous fiber to the fixing shaft, a step of flowing a plating solution from the fixing shaft to a plating bath via the wound fiber body so as to infiltrate the plating solution into the wound fiber body, and a step of performing electroless plating of silver, platinum, or the like on the fiber material while the plating solution flows.
