Multilayer graphene dispersion, blackening agent for thermophysical property measurement, release agent / lubricant for powder sintering

摘要

The present invention is a multilayer graphene dispersion capable of instantly producing a thin and uniform coating film containing multilayer graphene on the sample surface, a blackening agent for thermophysical property measurement excellent in blackening effect, and excellent in mold release and lubrication effect Provide mold release agent and lubricant for powder sintering. The multilayer graphene dispersion of the present invention is characterized in that multilayer graphene is dispersed in a liquid phase containing an organic solvent and a liquefied gas. The blackening agent for measuring thermophysical properties of the present invention is a blackening agent for forming a blackening film on the surface of a sample for measuring thermophysical properties, and comprises the multilayer graphene dispersion. Moreover, the release agent / lubricant for powder sintering of the present invention is a release agent / lubricant for forming a separation layer between a sintering die and a sintered body in powder sintering, It consists of the said multilayer graphene dispersion liquid.
