Polymer/MOF-derived multilayer fibrous membranes for moisture-wicking and efficient capturing both fine and ultrafine airborne particles

Recent advances in process engineering and upcoming applications of metal–organic frameworks

“…Wang et al prepared a multi-level structured membrane by compositing ZIF-8 with polyacrylonitrile (PAN) using a facile electrospinning process ( Fig. 29 a–c) [230] . The fibrous PAN/ZIF-8 composite membrane demonstrated good moisture wicking ability and particulate matter filtration.…”

Biocompatible chitosan-modified core-shell Fe3O4 nanocomposites for exigent removal of blood lactic acid

“…SEM analysis showed that the established nanoparticles were of good dispersion, and that no significant agglomeration occurred ( figure 1(a)). Therefore, a relatively larger specific surface area would be present for the better adsorption performance [20]. The FTIR spectrum of those nanoparticles was presented in figure 1(b).…”

Self-decontaminating nanofibrous filters for efficient particulate matter removal and airborne bacteria inactivation

“…This is probably due to the higher fiber charge, chaotic airflow and larger local fiber diameter favorable for interception and diffusion depositions by the hierarchical MOF particles within the electrospun fibers. [66][67][68] As shown in Fig. 3f, the UiO-PQDMAEMA@PAN filter is endowed with hierarchical structures, which contain both micropores and mesopores by embedding the porous UiO-PQDMAEMA particles in the electrospun fibers.…”
