Abstract

The invention belongs to the technical field of polymer composite materials, and particularly relates to modified boron nitride, a preparation method and application thereof, a polyaryletherketone composite material and a preparation method. The modified boron nitride provided by the invention has good thermal stability, and has no obvious thermal decomposition before 460 DEG C. According to the modified boron nitride provided by the invention, the fluorine-containing group is grafted on the surface of the modified boron nitride through surface functionalization, so that the boron nitride can participate in the preparation process of the polyaryletherketone, and the covalent bond modification of the polyaryletherketone by the boron nitride is realized. The modified boron nitride provided by the invention has good thermal stability, can be used for modifying resin, especially polyaryletherketone resin, can remarkably improve the heat-conducting property and mechanical property of the resin, and has an extremely important effect on preparation of a high-heat-conducting polyaryletherketone composite material. The polyaryletherketone composite material provided by the invention is modified by the modified boron nitride in the scheme, so that the polyaryletherketone composite material has good heat-conducting property and mechanical property.
