Our cars, which offer comfort to your life, can threaten our health if necessary precautions are not taken. Because the air we breathe in our vehicle during travel consists of volatile organic compounds (VOCs). Pollution inside a car cabin is high because emissions from the environment circulate in the car cabin.
Silk is a protein fiber produced naturally by insect larvae for the purpose of manufacturing a cocoon, with some of the best-known silk obtained from the mulberry silkworm. Recently, scientists have developed a new approach to nanofiber production inspired by the head bobbing of silkworms.

This can lead to the death of aquatic plants and animals, contaminate soil, and ultimately threaten human health.
Filtration and separation materials have gradually become a research hotspot on account of the increasing attention paid to the global environmental pollution problem. However, most filtration and separation materials can not balance the contradiction between high filtration & separation efficiency and its reusability. In this work, we report the successful fabrication of polyethersulfone@MOF (PESU@MOF) membranes using electrospinning with 1.22 ± 0.55 µm diameter, owning excellent mechanical property and high filtration efficiency (>99 %). For heat, acid and alkalic condition treatment, the stress of PESU@MOF-0.1 membrane slightly decreases to 0.50 ± 0.01 MPa under heating 12 h at 200 ℃. At the same time, the stress of PESU@MOF-0.1 membrane declines dramatically after treated by 1.0 mol/L HCl and NaOH, respectively, for 4 h. Moreover, compared with PESU membranes, quality factor (QF) value (0.12 Pa−1) of PESU@MOF-0.075 membrane increases by nearly 134.1 %, exhibiting excellent filtrati
