Abstract

The effect of oligophenylene sulfone (OPSU) and polycarbonate (PC) on the rheological, mechanical and thermal properties of polyetherimide (PEI) and a carbon-filled composite based on it was studied. It is shown that the introduction of OPSU and PC leads to a decrease in the melt viscosity of PEI and a carbon-filled composite based on it with the preservation of their mechanical properties and heat resistance at a sufficiently high level. It was found that composites with OPSU have higher mechanical and thermal properties compared with composites with PC. Samples from modified carbon-filled PEI were printed by the fused deposit modeling (FDM) method. Three-dimensionally printed samples from carbon-filled PEI modified by OPSU showed significantly higher mechanical properties than composites with PC.

摘要

研究了聚亚苯基砜（OPSU）和聚碳酸酯（PC）对聚醚酰亚胺（PEI）及其碳填充复合材料的流变学、力学和热性能的影响。结果表明，引入OPSU和PC会导致PEI及其碳填充复合材料的熔体粘度降低，同时在足够高的水平上保持其力学性能和耐热性。研究发现，与含PC的复合材料相比，含OPSU的复合材料具有更高的力学和热性能。采用熔融沉积成型（FDM）方法打印了改性碳填充PEI的样品。由OPSU改性的碳填充PEI制成的三维打印样品显示出比含PC的复合材料更高的力学性能。
