| 摘 要： | 以活性炭（AC）为吸附增强材料,石蜡为相变材料,采用物理共混法制备了一种固-固相变材料。利用差示扫描量热仪、导热系数测定仪、高温综合热分析仪对所得相变材料进行了表征。结果表明,当活性炭质量百分含量不低于15%时,所得复合物宏观上表现为固-固相变;加入活性炭颗粒,可提高材料的导热系数和热稳定性。

| Abstract: | The preparation and characterization of novel solid-solid phase change materials by blending were introduced with paraffin and active carbon as the main materials.The composites were characterized by differential scanning calorimetry,thermal conductivity device and thermo-gravimetric apparatus.The results indicated that the composites showed solid-solid phase change properties when the weight percent of active carbon was higher than 15%.The thermo-stability and the thermal conductivity of phase change materials both increased after adding active carbon. |
