生物碳增强聚丙烯复合材料：通过先进的动态原子力显微镜和X射线显微镜研究力学和填料行为CT
Biocarbon reinforced polypropylene composite: An investigation of mechanical and filler behavior through advanced dynamic atomic force microscopy and X-ray micro CT
摘要：
利用生物碳颗粒作为增强填料制备了聚合物复合材料，以改善其力学性能和热性能。然而，填料的分散和团聚的详细检查对于将填料基质和填料以及填料与产品的机械性能的相互作用相关联是必不可少的。我们研究了聚丙烯椰壳生物炭复合材料的力学性能、填料的团聚行为和热性能的变化。采用Brabender混炼机对PP/CSB复合材料进行了熔融共混实验，研究了CSB含量对PP/CSB复合材料性能的影响。使用原子力显微镜研究的复合材料的纳米力学映射显示，当CSB加载量从0增加到20重量百分比时，杨氏模量从1.6 GPa增加到2.9 GPa。利用X射线显微CT和专用三维重建软件对CSB填料在PP基体中的分散和团聚进行了三维重建。PP/CSB复合材料的热稳定性也随着CSB含量的增加而提高。
英文摘要：
Polymer composites were manufactured using biocarbon particles as a reinforcing filler to improve the mechanical and thermal properties. However, a detailed examination of dispersion and agglomeration of filler is essential to correlate the filler matrix and the filler and filler interactions with the mechanical properties of the product. We investigated the variations of mechanical, agglomeration behaviour of fillers, and thermal properties of polypropylene coconut shell biocarbon composites. PP CSB composites were prepared by melt mixing process varying the CSB content using a Brabender mixer. The nanomechanical mapping of the composites studied using Atomic Force Microscopy revealed an increase in Youngs modulus from 1.6 to 2.9 GPa when CSB loading increased from 0 to 20 weight percentage. The dispersion and agglomeration of CSB filler in the PP matrix were investigated using 3D reconstructed images with the help of X-ray micro CT, and a dedicated 3D reconstruction software. The thermal stability of the PP CSB composites also improved with an increase in CSB content in PP.
