Atmospheric particulate matter (PMs) pollution has raisedincreasingpublic concerns, especially with the outbreak of COVID-19. The preparationof high-performance membranes for air filtration is of great significance.Herein, the biosynthetic polymer poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) was adopted to create a hierarchical structureand biodegradable nonwoven membrane for PMs filtration through a faciledirectly electrospinning method. The as-prepared membranes with hierarchicalstructure contain abundant nanowires (5-100 nm) and microfibers(2-5 & mu;m) with different diameter (1000-5000 nm).We have achieved realization of formation mechanisms of such bimodalmicro- and nanofibers, which stem from the branching of microfiberat early stage of electrospinning. The PHBV membranes exhibit a veryhigh PM0.3 removal efficiency of 99.999% and PM2.5 removal efficiency of 100% with 0.077% standard atmospheric pressurein the air flow speed of 5.3 cm/s. More importantly, the PHBV membranescan be completely disintegrated within 1 week under composted conditions,indicating the great biodegradability of PHBV membranes. Our workprovides insights for the development of biodegradable, high performanceair filters for pollutants, molds, bacteria, and viruses.
