High-thermal-conductivity nano hot cable porous structure plate and preparation method thereof
The invention provides a high-thermal-conductivity nano hot cable porous structure plate and a preparation method thereof. The preparation method is a double-layer plate structure formed by sintering a porous structure material of a nano hot cable doped with multi-walled carbon nanotubes and a graphene material. Silver with high interfacial compatibility with the carbon nanotubes is adopted as the nano thermal cable core, the negative effect that the thermal conductivity is not obviously improved or even reduced due to poor material compatibility is avoided, the porosity is supplemented through the composite multi-walled carbon nanotubes, and normal work of the phase change liquid is ensured. And finally, the thermal conductivity of the plate is further improved by pressing graphene.
本发明提供了一种高导热性纳米热缆多孔结构板材及其制备方法，所述的制备方法是由纳米热缆掺杂多壁碳纳米管的多孔结构材料和石墨烯材料分别经过烧结形成的双层板材结构。本发明采用了与碳纳米管界面相容度高的银作为纳米热缆线芯，避免了因材料相容性不好导致的导热性无明显提升甚至下降的不良后果，并通过复合多壁碳纳米管补充孔隙率，确保相变液正常工作。最终通过压制石墨烯进一步提升板材导热性。
