摘要: 静电纺丝技术是制备纳米级复合纤维的有效手段，其产品在医用材料、柔性传感器等领域展现出广阔的应用前景。纳米纤维膜因其柔软、低模量、易变形等特性而备受关注。制备方法主要包括单针、同轴、多针阵列及无针静电纺丝。本研究首先采用单针静电纺丝法优化了制备热塑性聚氨酯(TPU)纤维膜的工艺参数。在此基础上，利用同轴静电纺丝技术，以纳米银/TPU (Ag-/TPU)为壳层，碳纳米管/TPU (CNT/TPU)为核层，成功制备了具有核壳结构的纳米复合纤维膜。通过傅里叶变换红外光谱(FTIR)、扫描电子显微镜(SEM)、热重分析(TGA)、差示扫描量热法(DSC)及光学视频接触角仪对复合纤维膜的化学结构、微观形貌、热性能和润湿性进行了系统表征。研究结果成功证实了一种核壳结构纳米复合纤维的制备可行性。
Abstract: Electrospinning technology is a common method for preparing nanoscale composite fibers, and the resulting fiber membranes have been widely used in fields such as medical materials and flexible sensors. Nanofiber membranes have attracted significant attention due to their softness, low modulus, and ease of deformation. The main preparation methods include single-needle, coaxial, multi-needle array, and needleless electrospinning. In this study, thermoplastic polyurethane (TPU) fiber membranes were first prepared using single-needle electrospinning to determine the optimal process parameters. Subsequently, a core-shell structure nanocomposite fiber membrane was fabricated via coaxial electrospinning, with a silver nanoparticle/TPU (Ag-/TPU) solution as the shell layer and a carbon nanotube/TPU (CNT/TPU) solution as the core layer. The chemical structure, micromorphology, thermal properties, and wettability of the prepared nanocomposite fiber membrane were characterized by using Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), Thermogravimetric Analysis (TGA), Differential Scanning Calorimetry (DSC), and optical video contact angle measurements. The research results successfully demonstrated the feasibility of the fabrication of a core-shell structure nanocomposite fiber.
