Abstract

Using a twin-screw microextruder, fibers are synthesized from polylactide with the addition of two types of chitin nanofibrils—both original and modified with poly(ethylene glycol). The fibers are subjected to the additional high-temperature orientational drawing by a factor of 4 and 6. Composite materials are investigated by a complex of thermophysical and structural methods, and their physicomechanical properties are determined. It is shown that the modification of chitin nanoparticles with poly(ethylene glycol) allows one to obtain bioresorbable composite materials with improved physicomechanical properties.

聚丙交酯和改性几丁质纳米原纤维复合纤维的物理力学性能研究

摘要

使用双螺杆微挤出机，通过添加两种类型的几丁质纳米原纤维（既是原始的又是用聚乙二醇改性的）由聚丙交酯合成的。对纤维进行额外的4倍和6倍高温定向拉伸。通过热物理和结构方法的综合研究复合材料，并确定其物理机械性能。结果表明，用聚乙二醇对几丁质纳米粒子的改性使得人们可以获得具有改善的物理机械性能的可生物吸收的复合材料。
