摘要

A high-performance Joule heater was fabricated using PET/GO-PA6 microfiber nonwovens, waterborne polyurethane, and NiFeMo alloy powder. The WPU uniformly and firmly immobilized the Gr and NiFeMo within the inter-fiber voids of the microfiber nonwovens, forming an efficient and continuous three-dimensional conductive network. The results indicate that increasing the graphene content and adding NiFeMo soft magnetic alloy powder significantly enhanced the electrothermal performance of the material. Specifically, when the graphene content reached 2 wt% and the alloy powder content was 1.5 wt%, the material achieves rapid temperature elevation from ambient to 58.32 °C within 10 s at 9 V, demonstrating excellent thermal response capability, while maintaining superior conductive stability with a conductivity retention rate exceeding 90% after five standard washing treatments, fully verifying the reliability and durability of its conductive network. In terms of comfort, the material exhibited a softness of 3.28 mm, an air permeability of 32.616 L/m2/s, and favorable mechanical properties. These results indicate that this material holds significant potential for applications in smart heating textiles.
