摘要： A filtration device containing a porous polyparaxylylene (PPX) filtration article is provided. The PPX filtration article includes at least one PPX polymer membrane layer and one or more substrate. Optionally, the PPX filtration article may include one or more support layer(s). The PPX polymer membrane has a pore size from about 1 nm to about 100 nm. The filtration article has a PVA_20 less than about 0.6 cm3/m2 and/or a mass/area (MPA) less than about 30 g/m2. The PPX filtration article separates and retains nanoparticles from a feed fluid with high permeability. In use, the PPX filtration article filters nanoparticles from a feed flow by passing the feed fluid through at least one PPX polymer membrane within the filtration article where the nanoparticles are separated and removed from the feed fluid. The PPX polymer membranes may be resistant to chemical attack, gamma radiation, and are thermally stable, biocompatible, and strong.

摘要： The present invention is directed to flexible conductive articles (600) that include a printed circuit (650) and a stretchable or non-stretchable substrate (610). In some embodiments, the substrate has a printed circuit on both sides. The printed circuit contains N therein a porous synthetic polymer membrane (660) and an electrically conductive trace (670) as well as a non-conducive region (640). The electrically conductive trace is imbibed or otherwise incorporated into the porous synthetic polymer membrane. In some embodiments, the synthetic polymer membrane is microporous. The printed circuit may be discontinuously bonded to the stretchable or non-stretchable substrate by adhesive dots (620). The printed circuits may be integrated into garments, such as smart apparel or other wearable technology.
