摘要

Porous polymer fibers, which integrate polymer flexibility with high surface area and tunable porosity, represent a burgeoning class of functional materials. Unlike previous reviews that focused on electrospun porous fibers or porous materials used for specific energy/separation functions, this review focuses on fibers and systematically explores their controllable synthesis from a cross-process perspective. These include electrospinning-assisted pore-forming techniques, phase separation, template processing, 3D printing, and key structure-function relationships that determine their properties. Key applications include environmental remediation (filtration and adsorption), energy storage (batteries and supercapacitors), biomedical engineering (tissue scaffolds and drug delivery), and advanced smart textiles. This further highlights emerging trends toward smart/wearable integration and the hybridization of porous fibers with advanced porous frameworks and conductive components. This review is expected to provide a viable research direction for porous polymer fibers.
