摘要
The integrated development of power devices puts forward higher requirements for the performance of thermal conductive materials. It is difficult to obtain high-performance thermally conductive materials by common methods. In this paper, composites with highly orientated hBN were prepared by DLP 3D printing. When the thickness of the 3D printing layer is less than the thickness of the hBN sheet, under the pressure of the printing platform, the large particle size hBN with higher content will align along the printing layer, thus achieving the orientation function, and the degree of orientation can also be adjusted by controlling the thickness of the printing layer. Because the hBN orientation direction plays an important role in the heat conduction of the composite resin, the oriented printing material can significantly increase the thermal conductivity. The dielectric constant of the composite with hBN is still low. The impact strength rises first and then decreases, and the bending strength has a more obvious increase, the maximum values of the two being 10.2KJ.m-2 and 135Mpa respectively. At 20% hBN content, thermal conductivity can reach 2.1 Wm-1K-1 when the heat flow is parallel to the orientation direction of hBN. The low-layer thickness orientation method has a high advantage over other current methods in thermal conductivity and mechanical properties, and it has broad application prospects in the field of 3D printing materials engineering.
