Abstract

In this study, we demonstrate the use of silicone/few-layered hexagonal boron nitride (FL-hBN) composites for heat dissipation applications. FL-hBN is synthesized via a green, facile, low-cost and scalable liquid exfoliation method using a jet cavitation process. The crystal structures, surface morphologies and specific surface areas of pristine h-BN and FL-hBN were characterized by XRD, SEM, TEM and AFM (atomic force microscopy). The results confirmed that FL-hBN with a thickness of ~4 nm was successfully obtained from the exfoliation process. In addition, we introduced both pristine h-BN and FL-hBN into silicone with different ratios to study their thermal properties. The results of the laser flash analysis indicate that the silicon/FL-hBN composite exhibited a higher thermal conductivity than that of the silicone/h-BN composite. With the optimal loading content of 30 wt.% FL-hBN content, the thermal conductivity of the composite could be enhanced to 230%, which is higher than that of silicone/h-BN (189%). These results indicate that jet cavitation is an effective and swift way to obtain few-layered hexagonal boron nitride that could effectively enhance the thermal conductivity of silicone composites.

摘要

在本研究中，我们展示了硅酮/少层六方氮化硼（FL-hBN）复合材料在散热应用中的使用。FL-hBN是通过一种绿色、简便、低成本且可扩展的液体剥离方法，利用喷射空化过程合成的。通过X射线衍射（XRD）、扫描电子显微镜（SEM）、透射电子显微镜（TEM）和原子力显微镜（AFM）对原始h-BN和FL-hBN的晶体结构、表面形态和比表面积进行了表征。结果证实，通过剥离过程成功获得了厚度约为4纳米的FL-hBN。此外，我们将原始h-BN和FL-hBN以不同比例引入硅酮中，以研究它们的热性能。激光闪光分析结果表明，硅/FL-hBN复合材料的热导率高于硅酮/h-BN复合材料。当FL-hBN的最佳负载量为30重量%时，复合材料的热导率可提高到230%，高于硅酮/h-BN（189%）。这些结果表明，喷射空化是获得少层六方氮化硼的一种有效且快速的方法，能够有效提高硅酮复合材料的热导率。
