Disclosing a kind of insulation layer composition for substrate herein and use its prepreg and substrate, described insulation layer composition comprises soluble type liquid crystal thermosetting oligomer, metallic alkoxide compound and graphene oxide.Insulation layer composition according to the present invention can effectively reduce its thermal coefficient of expansion, thus, when this insulation layer composition is used as the insulant of substrate, can make to minimize due to the change in size of heat, cause substrate to have the heat stability of improvement. |
