Air pollution is caused by the perilous accumulation of particulate matter (PM) and harmful gas molecules different sizes. There an urgent need to develop highly efficient air filtration systems capable removing particles with a wide size distribution. However, efficiency current filters compromised controlling their hierarchical pore size. Inspired graded mechanisms in human respiratory system, microporous ZIF-67 situ synthesized on 3D interconnected network bamboo cellulose fibers (BCFs) fabricate multiscale porous filter comprehensive The macropores between BCFs, mesopores formed BCF microfibers, micropores within synergistically facilitate removal particulates capabilities PM2.5 PM0.3 could reach 99.3% 98.6%, respectively, whereas adsorption formaldehyde 88.7% 30 min. In addition, exhibits excellent antibacterial properties (99.9%), biodegradability (80.1% degradation after 14 days), thermal stability, skin-friendly (0 irritation). This study may inspire research using natural features renewable resources design high-performance air-filtration materials for various applications.

Abstract In response to the health and environmental concerns associated with plasticizer dioctyl phthalate (DOP), this research explores utilization of methyl oleate (MO) derived from plant oil, 1,2,4‐Benzeneticarboxylic anhydride (TMA) isobutyric (IA) as a precursor for synthesizing hyperbranched polyester named IA‐MO‐TMA. This serves an alternative Polyvinyl chloride (PVC). The chemical structure IA‐MO‐TMA was thoroughly characterized using Fourier Transform Infrared Spectrometer (FTIR) nuclear magnetic resonance hydrogen spectra, its molecular weight assessed. PVC film, plasticized IA‐MO‐TMA, underwent comprehensive testing techniques such differential scanning calorimetry, electron microscopy, thermogravimetric analysis. Notably, glass transition temperature ( T g ) film exhibited significant reduction 75°C −6.7°C. demonstrated elongation at break 318.1%, tensile strength 19.2 MPa, plasticizing efficiency 109.9%. Moreover, use increased initial decomposition 235.6 264.1°C. Additionally, extraction rate in petroleum ether found be 35.6% lower than that DOP.
