摘要

利用可变氮化硼(BN)和少量石墨烯纳米颗粒(GNPs)(1 wt%)制备了具有出色导热性能的自愈合聚氨酯二丙烯酸酯(PUDA)复合材料。含有 1 wt% GNPs 和 29 wt% BN 的 PUDA 复合材料的热导率达到了 1.73 W/(m-K),与仅含有 30 wt% BN 的 PUDA 复合材料相比提高了 27.2%。BN 和 GNPs 相互促进在 PUDA 基体中的分散,少量的 GNPs 足以弥合 BN 之间的间隙,因此 GNPs 和 BN 对 PUDA 复合材料的热导率产生了协同增强效应,协同效率为 1.343。PUDA 复合材料保持了 8.21 MPa 的拉伸强度和良好的电绝缘性(4.55 × 109 Ω cm)。通过可逆 DA 反应的愈合作用,还实现了机械强度(大于 90%)和热导率(大于 84%)的高度恢复。具有优异综合性能的 PUDA 复合材料在电子设备的热管理方面具有广阔的应用前景。

Enhanced thermal conductivity and self-healing property of PUDA/boron nitride micro-sheets composites with a small number of graphene nano-platelets

Self-healing polyurethane diacrylate (PUDA) composites with outstanding thermal conductivity were prepared with variable boron nitride (BN) and a small number of graphene nanoplatelets (GNPs) (1 wt%). The thermal conductivity of PUDA composites containing 1 wt% GNPs and 29 wt% BN reached 1.73 W/(m·K), showing 27.2% increment compared to PUDA composites only with 30 wt% BN. BN and GNPs mutually promoted the dispersion in the PUDA matrix, and the small number of GNPs was enough to bridge the gaps between BN, so that GNPs and BN exerted a synergistic enhancement effect on the thermal conductivity of PUDA composites with a synergistic efficiency of 1.343. The PUDA composites maintained the tensile strength of 8.21 MPa with good electrical insulation (4.55 × 109 Ω cm). The high degrees of recovery of mechanical strength (>90%) and thermal conductivities (>84%) were also realised by the healing effect of the reversible DA reaction. The PUDA composites with excellent comprehensive properties show broad application potential in the thermal management of electronic devices.
