چکیده مقاله:
A new method for the production of nanoscaled polymeric films with a width of 10 cm and of infinite length is presented. The principle is based on a modified water casting method where a polymer solution spreads on a water surface and is wound up by a rotating cylinder. The film thickness depends on several parameters and varies from 30 to 1000 nm. In contrast to most processes for the production of thin polymeric films, the one described here can be driven continuously and allows a production speed of up to 10 m:min. Films were produced from various commercially available polymers and were investigated regarding surface quality, molecular orientation and gas permeation properties. a novel catalytic membrane was synthesized by grafting a poly(ionic liquid) (PIL) onto polypropylene (PP) membrane followed by complexing with polyoxometalate (POM).
