DISPERSION METHOD OF CARBON NANOMATERIAL IN POLYMER RESIN USING ETHYL ALCOHOL AS DISPERSANT

摘要

PURPOSE: Provided is a method for dispersing a nanomaterial to reduce the energy required for the dispersion of a nanomaterial and to allow a dispersant to be collected easily for reducing the cost. CONSTITUTION: The method comprises the steps of dispersing a nanomaterial(M) by using a dispersant(E); adding a resin(R) to the mixture of a nanomaterial and a dispersant and stirring the mixture; extracting the dispersant from the obtained mixture; and curing the obtained mixture to prepare a product. Preferably the nanomaterial is a carbon nanomaterial; the dispersant is ethyl alcohol; and the resin is a polymer epoxy resin. Preferably the extraction process comprises the steps of separating and layering the dispersant from the nanomaterial and the resin to remove it; and removing the dispersant by volatilization.
