| 摘 要： | 采用纳米铜作为子颗粒,利用颗粒复合化系统,以机械冲击的方法将纳米铜颗粒嵌入式包覆于超高分子量聚乙烯颗粒(UHMWPE)表面,利用热压成形技术制备导热型复合材料。采用导热系数测定仪测试其导热系数,分析纳米铜添加量对导热效果的影响。结果表明:在相同的实验条件下,当纳米铜添加质量分数为6.8%时,复合材料的导热系数达到了0.85 W/(m.K),比纯UHMWPE提高了124%。

| Abstract: | The nano-sized copper(Cu) particles with high thermal conductivity was added in ultra-high molecular weight polyethylene(UHMWPE).Using the particles composite system(PCS),the surfaces of UHMWPE particles were coated with nano-sized copper(Cu) particles by mechanical impact.The heat conducting composite materials were prepared by heat compression molding.The thermal conductivities of different nano-composites were measured by heat conductive instrument.The influences of different nano-sized copper(Cu) particles contents on thermal conductivity were analyzed.The results showed that the thermal conductivity of UHMWPE nano-composites was advanced by 124%.It was 0.85 W(/m·K),when the mass ratio of 6.8% nano-sized copper(Cu) particles was added under the identical experimental conditions. |
