The invention relates to multifunctional optically highly transparent films based on cellulose esters, having the following components within a film: a) a cellulose ester or a mixture of cellulose esters, preferably based on cellulose triacetate, which can be processed into a highly transparent film with a haze value of
摘要:
Water vapor transport membranes for ERV and other water vapor transport applications are provided. The membranes include a substrate and an air impermeable selective layer coated on the substrate, the selective layer including a cellulose derivative and a sulfonated polyaryletherketone. In some embodiments the sulfonated polyaryletherketone is in a cation form and/or the selective layer includes s PEEK and CA in an s PEEK:CA (wt.:wt.) ratio in the range of about 7:3 to 2:3. Methods for making such membranes are provided. The methods include applying a coating solution/dispersion to a substrate and allowing the coating solution/dispersion to dry to form an air impermeable selective layer on the substrate, the coating solution/dispersion including a cellulose derivative and a sulfonated polyarylether ketone. In some embodiments the sulfonated polyaryletherketone is in a cation form and/or the coating solution/dispersion includes s PEEK and CA in an sPEEK:CA (wt.:wt.) ratio in the range of about 7:3 to 2:3.

摘要:
The present invention relates to a process for the preparation of films of conductive polymers, by the technique so-called roll-to-roll, which allows to obtain freestanding films having advantageous features such as toughness, flexibility, ability to adhere to different substrates, a submicron thickness and a very high ratio surface area/thickness; the present films are suitable for use in several technological applications, in particular for the development of biosensors, and in the production of flexible electronic components with large surface, suitable for wearable devices and also intended for contacting skin.
