This research investigates a novel composite of encapsulated paraffin in boron nitride nanotube (BNNT) which is more thermally and chemically stable than carbon nanotube. This composite can achieve high thermal conductivity and, meanwhile, have thermal energy storage capability for efficient thermal management under extreme conditions. Equilibrium molecular dynamics simulations were conducted to study self-diffusion coefficient, thermal conductivity, and specific heat of encapsulated paraffin. The simulation results indicated that the self-diffusion coefficient and thermal conductivity of paraffin could be increased by up to 10 and 7 times, respectively, while specific heat was reduced after encapsulating into BNNT.

这项研究研究了一种新型的氮化硼纳米管（BNNT）中封装的石蜡复合材料，该复合材料比碳纳米管在热和化学上更稳定。这种复合材料可以实现高导热率，同时具有蓄热能力，可以在极端条件下进行有效的热管理。进行了平衡分子动力学模拟，以研究包封石蜡的自扩散系数，热导率和比热。模拟结果表明，石蜡的自扩散系数和导热系数可以分别提高10倍和7倍，而包封在BNNT中的比热则降低了。
