▎ 摘　　要

NOVELTY - An aqueous titanate is dissolved in water. Graphene powder is added to mixture and ultrasonically dispersed in magnetic field, to obtain graphene dispersion. Graphene dispersion is distilled or vacuum distilled under applied magnetic field, to obtain graphene concentrate. Graphene concentrate and caprolactam are added to polymerization system and thermally polymerized, to obtain high-strength thermally-conductive nylon 6. USE - Preparation of high-strength thermally-conductive nylon 6 (claimed). ADVANTAGE - The method enables preparation of thermally-conductive nylon 6 having excellent strength, graphene dispersion characteristics and thermal conductivity, and suppressed agglomeration.
