A thin carbon layer (~1.15μm thick) was fabricated on coarse polyethylene terephthalate (PET) fibers via in-situ modification with sucrose-derived carbon (SDC), which only occupied 10-3 of the fiber's pore size and significantly improved the dielectric properties. The composite filter material achieved a high filtration efficiency of 98.10% for 0.3μm particles while maintaining low resistance, resulting in a comprehensive quality factor (CQF) significantly higher than that of the origin PET fibers. Furthermore, the carbon layer was strongly bonded to the PET fibers, ensuring excellent long-term stability and suitability for repeated use.
