Abstract
This work shows that the surface properties of polyurethane acrylate (PUA) films can be controlled by the coating of nanoporous organic networks (NONs). By the NON coating, the hydrophilic nature of nanostructured PUA (N-PUA) film was converted to superhydrophobic surface. The NON-coated N-PUA films (N-PUA-NONs) were applied as stationary adsorbents for the capture of particulate matter (PM) in air. Compared with the original PUA films, the N-PUA-NON films showed much enhanced capture performance toward PM and recyclability through water washing, indicating the potential of outdoor application as stationary self-cleaning adsorbents under natural surroundings.
