▎ 摘　　要

NOVELTY - A nano-modified silane/siloxane agent preparing method involves dissolving graphene, small molecule alcohol and ester solvent through ultrasonic dispersion for 60 minutes to form an uniform dispersion graphene dispersion liquid, mixing isooctyl triethoxy silane, isobutyl triethoxysilane ester and small molecule solvent through a machinery stirrer for 15-45 minutes to obtain organic silicon, followed by mixing graphene dispersion liquid and organic silicon through the machinery stirrer at mixed ratio of 1:3-1:10 to obtain nano-modified silane/siloxane agent. USE - Method for preparing nano-modified silane/siloxane agent.
