METHOD FOR PRODUCING DISPERSION LIQUID OF FLAKED GRAPHITE, METHOD FOR PRODUCING FLAKED GRAPHITE AND METHOD FOR PRODUCING COMPOSITE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a dispersion liquid of flaked graphite, in which high-temperature heating is not required.;SOLUTION: The method for producing the dispersion liquid of flaked graphite, in which flaked graphite is dispersed uniformly in a dispersion medium without heating the dispersion liquid at high temperature, comprises the steps of: flaking graphite oxide in a first dispersion liquid, which is obtained by dispersing graphite oxide in the dispersion medium, to produce a second dispersion liquid in which the flaked graphite oxide is dispersed; and irradiating the second dispersion liquid with ultrasonic waves having 100-500 kHz frequency to reduce the flaked graphite oxide.;COPYRIGHT: (C)2011,JPO&INPIT
