摘要

摘要: 为了改善金刚石在聚合物中的均匀分散性，并提高导热性能，以不同粒度的金刚石和聚丙烯腈（PAN）共聚物为原料，采用静电纺丝方法制备得到金刚石/PAN杂化复合纤维。通过改变纺丝溶液中金刚石的添加量，研究了不同金刚石含量及不同粒度的金刚石对金刚石/PAN杂化复合纤维形态和热性能的影响。研究结果表明，静电纺丝可以有效解决微米级金刚石在PAN聚合物中的分散问题，金刚石的粒度对纺丝的稳定性和连续性影响很大，粒度为0.5~1 μm的金刚石经过纺丝可以有效地包覆在纤维中。当金刚石的粒度大于1~2 μm时，纺丝时稳定性差，纤维中很少或几乎没有包覆金刚石颗粒。当金刚石粒度为0.5~1 μm、实际质量分数为38.5wt%时，金刚石/PAN杂化复合纤维热导率最高，达到1.923 W/（m·K）。

Abstract: In order to increase the distribution of diamond particles and the thermal conductivity of polyacrylonitrile(PAN) copolymers, the diamond/PAN hybrid composite fibers were obtained via electrospinning using PAN and different sized diamonds as raw materials. The effects of different contents and various sizes of diamond on the morphology and thermal properties of diamond/PAN composite fibers were studied with changing the mass fraction of diamond addition. The results show that electrospinning can give the ability to deliver microdiamonds in the form of well-dispersed particles into the polymer matrix, and the stability and continuity of the spinning are greatly affected by the particle size of the diamonds. The size of diamond of 0.5-1 μm can be effectively coated in the diamond/PAN fiber, and the thermal conductivity of diamond/PAN fibers reaches 1.923 W/(m·K) when the actual mass fraction of diamond is 38.5wt%. However, when the size of diamond particles is greater than 1-2 μm, the stability of the spinning is poor. As a result, it will lead to the diamond being little or not even appearing in the diamond/PAN fibers.
