摘要

In order to explore the preparation and properties of PCL/PVA/CNTs composite fibers, PCL was chosen as the matrix material of the composite fibers, and PVA and CNTs were added as reinforcing materials into the PCL spinning solution, and PCL/PVA/ CNTs-COOH composite fibers were prepared by electrostatic spinning technology. The structure, thermal properties, mechanical properties, degradation properties, electrical resistivity and biocompatibility (cytotoxicity) of the composite fibers were also tested and analyzed. The results showed that the incorporation of PVA could provide significant mechanical strength and hydrophilicity for the composite fibers, and the incorporation of CNTs-COOH could provide electrical conductivity and degradation rate for the composite fibers, as well as a small enhancement of the hydrophilicity of the materials, and the best overall performance of the fibers was achieved at a content of CNTs-COOH of 1 wt%, and the cytotoxicity results were also in accordance with the safety standards.
