可降解微纳米纤维制备工艺及应用的研究进展OA

Driven by the urgent need for environmental sustainability,biodegradable micro-and nanofibers have emerged as promising materials across diverse sectors due to their tunable morphology,high surface-to-volume ratio,and eco-friendly degradation profiles.This review provides a comprehensive overview of several biodegradable polymer matri-ces,and discusses their degradation mechanisms under various environmental conditions.Four key fabrication techniques are critically analyzed:electrospinning,melt-blown spinning,centrifugal spinning,and phase separation spinning.For each method,the underlying principles,process advantages,material compatibility,and limitations are analyzed to guide technology selection based on application requirements.The performance and current challenges of biodegradable micro/nanofibers are further evaluated in three high-impact application domains,including high-efficiency filtration,tissue engi-neering,and food packaging.Despite significant progress,barriers remain in scalability,cost-effectiveness,and environ-mental robustness.Future research should prioritize the development of energy-efficient,solvent-free processes,hybrid material systems with balanced degradation-performance profiles,and standardized protocols for real-world deployment.Addressing these challenges will accelerate the transition of biodegradable micro/nanofibers from laboratory innovation to industrial and clinical adoption.
