With the increasing attention to global air quality problem, air ltration materials become a research hotspot. Here, novel polyurethane (PU)/polyvinylidene uoride (PVDF)@ polypropylene (PP) multi-scale membranes were fabricated by a lamination process of electrospinning and melt-blown methods. The electrospinning nano-membrane and melt-blown micro-membrane were optimized under various parameter. The morphology and structures of the prepared multi-scale membranes were characterized by SEM and FT-IR. And the water contact angle was tested to evaluate the wettability properties. Air ltration tests was operated to determine the optimum membranes for air ltration application. The results showed that the multi-scale membranes had highly air ltration e ciency (96.72%) and quality factor (0.04167 Pa − 1 ) which can be obtained by only electrospinning 60 min. The successful preparation of multi-scale membranes provides a new way for the design and development of electrospinning lteration membranes. In addition, large-scale production of air ltration membranes with high ltration e ciency and low pressure drop can be realized by combine electrospinning and melt-blown technology.

With the increasing attention to global air quality problem, air filtration materials become a research hotspot. Here, novel polyurethane (PU)/polyvinylidene fluoride (PVDF)@ polypropylene (PP) multi-scale membranes were fabricated by a lamination process of electrospinning and melt-blown methods. The electrospinning nano-membrane and melt-blown micro-membrane were optimized under various parameter. The morphology and structures of the prepared multi-scale membranes were characterized by SEM and FT-IR. And the water contact angle was tested to evaluate the wettability properties.
