摘要:

为克服癸酸-棕榈酸-硬脂酸(CA-PA-SA)三元低共熔物液相渗漏和导热性能差的问题,以不同质量比的静电纺聚丙烯腈/氮化硼(PAN/BN)复合纳米纤维膜作为支撑材料,通过物理吸附法制备新型CA-PA-SA/PAN/BN复合相变纤维膜,并研究了BN导热纳米粒子对复合相变纤维膜的形貌结构、储热性能以及储热和放热速率的影响。结果表明:添加质量分数为10%的BN导热纳米粒子对制备的CA-PA-SA/PAN/BN复合相变纤维膜的形貌结构没有影响;复合相变纤维膜的融化温度和融化焓值分别为25 ℃和136.4~138.6 kJ/kg;通过添加具有高导热系数的BN纳米粒子,CA-PA-SA/PAN/BN复合相变纤维膜的整体传热性能增强,储热和放热时间分别缩短了38%和41%。

Abstract:

Electrospun polyacrylonitrile/boron nitride (PAN/BN) composite nanofibrous membranes with different mass ratios were used as supporting materials to overcome the problems of poor thermal conductivity and the leakage problems of capric acid-palmitic acid-stearic acid (CA-PA-SA) ternary eutectic acting as solid-liquid phase change materials. And then innovative CA-PA-SA/PAN/BN composite phase change fibrous membranes were prepared by physical adsorption. The influences of BN nanoparticles with high thermal conductivity on their morphological structure, thermal performance, as well as thermal energy storage and release rates were studied. The scanning electron microscopy images reveals that the morphological structure of CA-PA-SA/PAN/BN composite phase change fibrous membranes are unaffected by the addition of 10 % BN nanoparticles. The differential scanning calorimetry results suggest that the melting temperatures and enthalpies of the prepared composite phase change fibrous membranes are about 25 ℃ and 136.4-138.6 kJ/kg, respectively. Heat transfer test results indicate that the integral heat transfer performance of CA-PA-SA/PAN/BN composite phase change fibrous membranes are improved by virtue of the addition of BN nanoparticles with high thermal conductivity, and their melting and freezing times are shortened about 38% and 41%, respectively.

Key words: composite phase change fibrous membrane, boron nitride, capric acid-palmitic acid-stearic acid ternary eutectic, thermal energy storage property, heat transfer property
