To develop an advanced heat transfer composite, a deeper understanding of the interfacial correlation between matrix and filler is of paramount importance. To verify the effect of interfacial correlations on the thermal conductivity, the conductive fillers such as expanded graphite (EG) and boron nitride (BN) are introduced in the discotic liquid crystal (DLC)-based polymeric matrix. The DLC matrix exhibits better interfacial affinity with EG compared to BN because of the strong π–π interactions between EG and DLC. Thanks to its excellent interfacial affinity, the EG-DLC composites show a synergistic increment in thermal conducting performance.

协同提高盘状液晶复合材料导热系数的界面工程

为了开发一种先进的传热复合材料,对基体和填料之间的界面相关性的深入了解至关重要。为了验证界面相关性对热导率的影响,将导电填料(例如膨胀石墨(EG)和氮化硼(BN))引入基于盘状液晶(DLC)的聚合物基体中。与BN相比,DLC基质与EG表现出更好的界面亲和力,因为EG与DLC之间存在很强的π-π相互作用。由于其优异的界面亲和力,EG-DLC复合材料在导热性能方面显示出协同增效作用。
