Abstract
With the growing problem of environmental pollution,the demand for nonwoven materials with ef-ficient filtration properties is growing rapidly.The energy burden and environmental concerns associated with tra-ditional 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,compoun-ding/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 technolo-gy,after-finishing and other methods,the performance of PLA meltblown nonwoven materials significantly im-proved,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 devel-opment.关键词
