【Abstract】 With the growing problem of environmental pollution, the demand for nonwoven materials with efficient filtration properties is growing rapidly. The energy burden and environmental concerns associated with traditional petroleum-based polymer materials have prompted interest in bio-based nonwovens. Polylactic acid(PLA), as a bio-based degradable polymer, shows great potential in the field of meltblown nonwoven materials. In this paper, the latest research progress in PLA-based meltblown nonwoven materials was reviewed, including processing and moulding, process optimization, modification methods(blending/copolymerisation, compounding/doping, electret modification and other treatments), and applications in the fields of air filtration, medical and healthcare, food preservation and oil-water separation. Through raw material design, modification technology, after-finishing and other methods, the performance of PLA meltblown nonwoven materials significantly improved, showing application prospect in many fields. With technological advance and increasing environmental protection awareness, PLA-based meltblown nonwoven materials will play an important role in sustainable development.更多还原
