摘 要:氮化硼纳米片(BNNS)具有优异的导热性和绝缘性,但与聚合物基体相容性差,限制 了其在热界面材料中的应用。为了解决此问题,使用 6-氨基己酸(ACA)辅助水球磨来改善 BNNS 的表面性能。BNNS@ACA 被分散到聚二甲基硅氧烷(MVQ)基体中改善了复合材 料的导热性能和耐热性能。在 15%(质量分数) BNNS@ACA 填充的情况下,复合材料的热 导率达到 0. 732 W ·(m · K)−1 ,比纯 MVQ 提高了 490%。实现了具有低 BNNS@ACA 填充 量的 MVQ 基复合材料的高导热性。同时,使用分子模拟表征复合材料的界面热阻和相互作 用能,在分子水平上解释热导率增强的机制。

Abstract:Boron nitride nanosheets (BNNS) have excellent thermal conductivity and insula⁃ tion properties, but their poor compatibility with polymer matrices limits their application in thermal interface materials. To address this issue,6-aminocaproic acid (ACA)-assisted water ball milling was used to improve the surface properties of BNNS. BNNS@ACA was dispersed into the polydimethylsiloxane (MVQ) matrix to improve the thermal conductivity and heat resistance of the composite. With 15% BNNS@ACA filling, the thermal conductivity of the composite reaches 0. 732 W ·(m · K)−1 , which is 490% higher than that of pure MVQ. High thermal conductivity of MVQ-based composites with low BNNS@ACA filling capacity was achieved. Meanwhile, molecular simulations are used to characterize the interfacial thermal resistance and interaction energy of the composites, explaining the thermal conductivity enhancement at the molecular level.
