Abstract

Magnetic polymer-based composites combine the cost-effectiveness, low density, and manufacturing flexibility of conventional polymers with the unique characteristics of magnetic powders/fillers to form multi-functional magneto polymeric composites that offer superior properties to conventional materials. At higher temperatures, magnetic properties change significantly and the particles within the magnetic powders experience sporadic motion due to the heat which causes misalignment of the magnetic domains, leading to a decrease in magnetism. Due to these adverse temperature effects, high-performance polymers such as polyetheretherketone (PEEK), polyetherimide (PEI), high-performance polyamides (HPPA), or other high-temperature thermoplastics have been considered suitable matrix for the magnetic fillers, thereby creating a much wider usage for magneto polymeric composite in applications that requires higher temperature (typically above 175°C). Thus, this review discusses the fabrication processes-injection molding, fused filament fabrication; magnetic performance, and applications of high-performance thermoplastic-based magnetic composites that can be viable for stringent engineering devices such as sensors, actuators, motors, and generators.

高性能热塑性磁性复合材料

基于磁性聚合物的复合材料将传统聚合物的成本效益、低密度和制造灵活性与磁性粉末/填料的独特特性结合在一起，形成了多功能磁性聚合物复合材料，其特性优于传统材料。在较高温度下，磁性能会发生显著变化，磁粉中的颗粒会因受热而发生零星运动，导致磁畴错位，从而降低磁性。由于这些不利的温度影响，高性能聚合物（如聚醚醚酮（PEEK）、聚醚酰亚胺（PEI）、高性能聚酰胺（HPPA）或其他高温热塑性塑料）已被认为是磁性填料的合适基体，从而为磁性聚合物复合材料在需要较高温度（通常高于 175°C）的应用中创造了更广泛的用途。因此，本综述讨论了基于高性能热塑性塑料的磁性复合材料的制造工艺--注塑成型、熔融长丝制造、磁性能和应用，这些复合材料可用于传感器、致动器、电机和发电机等严格的工程设备。
