Abstract

3D printing is a promising technology for creating polymer objects of a given architecture with specified functional properties. In fact, the choice of filaments for 3D printing is quite limited. Here, we report a process for producing polystyrene filaments with 0.0025–2 wt.% single-walled carbon nanotubes (SWCNTs) by extruding crushed polystyrene composites. The resulting filaments are characterized by a high uniformity of filler distribution and the absence of air pores. Comparison of microscopy data and electromagnetic properties of base composites and composite materials printed from filaments showed that extrusion and printing improve SWCNT dispersion. The proposed method can be used to create filaments for 3D printing of objects from various base polymers containing functional fillers up to the electrical percolation threshold and above.

用于3D打印的碳纳米管-聚苯乙烯长丝的制造:纳米颗粒的分散和电磁性能

3D打印是一种很有前途的技术，可以创建具有特定功能特性的给定结构的聚合物物体。事实上，3D打印材料的选择非常有限。在这里，我们报告了一种通过挤压破碎的聚苯乙烯复合材料来生产含有0.0025-2 wt.%单壁碳纳米管(SWCNTs)的聚苯乙烯长丝的工艺。所得长丝的特点是填料分布均匀性高，没有气孔。基材复合材料和长丝印刷复合材料的显微镜数据和电磁性能比较表明，挤压和印刷提高了swcnts的分散性。所提出的方法可用于从含有功能填料的各种基础聚合物中创建用于3D打印对象的细丝，直至电渗透阈值及以上。
