Abstract

Nanomodified polyetherimide samples obtained by fused deposition modeling using an experimental setup for three-dimensional printing of highly heat-resistant plastics are studied. Their structure and thermal properties are investigated by pycnometry, scanning electron microscopy, differential scanning calorimetry, thermogravimetry, and dilatometry. It is found that the modification of polyetherimide with carbon nanofibers considerably reduces the porosity of printed samples. An analysis of cytotoxicity shows that the tested materials are bioinert.

聚醚酰亚胺及其纳米复合材料3D打印样品的生物医学应用研究

摘要

研究了通过熔融沉积建模获得的纳米改性聚醚酰亚胺样品，该实验使用了用于高耐热塑料三维印刷的实验装置。通过比重法，扫描电子显微镜，差示扫描量热法，热重法和膨胀法研究了它们的结构和热性能。发现用碳纳米纤维对聚醚酰亚胺进行改性大大降低了印刷样品的孔隙率。细胞毒性分析表明，所测试的材料是生物惰性的。
