Abstract

The invention discloses a surface-functionalized BN nanosheet, and a preparation method and application thereof, belonging to the field of preparation and modification of BN nanosheets. The preparation method of the surface-functionalized BN nanosheet comprises the following steps of: uniformly mixing and grinding tritonX-100 and BN nanosheets, adding the mixed and ground mixture into an organic solvent, carrying out heating and stirring in a reflux condensation state, carrying out ultrasonic dispersing and stripping to obtain a surface-functionalized BN nanosheet suspension, and removing a solution to obtain the surface-functionalized BN nanosheet. TritonX-100 molecules on the surfaces of the BN nanosheets in the surface functionalized BN nanosheets are subjected to surface functionalization, so the BN nanosheets can be more uniformly dispersed in a polymer matrix; meanwhile, the surface functionalized BN nanosheets are physically entangled with polymer matrix molecules, so the intermediate interface interaction between the surface functionalized BN nanosheets and the polymer matrix is enhanced, and the interface modification remarkably improves the mechanical property and the thermal conductivity of a modified polymer system.

Description

technical field

[0001] The present invention relates to the technical field of preparation and modification of BN nanosheets, in particular to a surface functionalized BN nanosheet and its preparation method and application. epoxy adhesive. Background technique

[0002] Due to its light weight, easy processing and low cost, polymer materials are now mostly used to support and protect electronic products. With the development of modern electronic products to faster speed and frequency, smaller size and more functions, heat dissipation has become a a key question. Unfortunately, most polymer materials do not have ideal thermal conductivity, for example, epoxy and silicone gel exhibit poor thermal conductivity, so they cannot meet the needs of modern electronic products for fast heat transfer.

[0003] Thermally conductive adhesives are one of the polymer materials. The way to improve their thermal conductivity is to add fillers with high thermal conductivity to the resin, an...
