A PROCESS FOR PREPARING FREE-STANDING FILMS OF CONDUCTIVE POLYMERS
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.
Protective film press and method of use
A protective film press using commercially available anti-graffiti film for the production of a multi-layer protective film. The invention provides a relatively simple and economical manufacturing device and method to produce a multi-layer protective film which has historically required expensive and complex methods and equipment. The protective film press comprising a frame chassis, a plurality of mounting assemblies detachably attached to the frame chassis, first and second motorized pull roller assemblies repositionably mounted on the frame chassis, a pair of pressure rollers that pneumatically press the anti-graffiti films into a vertically stacked multi-layer configuration, and at least one alignment roller repositionably mounted on the frame chassis. A preferred embodiment of present invention also includes means for controlling the speed at which the first and second motorized pull roller assemblies operate and also a means for providing pressure for the pair of pressure rollers.

Acrolein scavenging in PTF and other 1,3-propanediol derived polymers
This disclosure provides a process for removing acrolein or allyl alcohol from a polyester composition, the process comprising: combining a polyester composition derived from 1,3-propanediol with an amino amide or a primary amine; wherein the amino amide or the primary amine is combined in sufficient quantities to scavenge acrolein or allyl alcohol produced from degradation of the polyester composition. An analysis of reactions between anthranilamide (AAA) and acrolein demonstrates how amines or amino amides can scavenge acrolein from thermally processed poly(trimethylene terephthalate) and poly(trimethylene furan-2,5-dicarboxylate), and thermodynamic models are presented as guidance for matching targets with scavenging agent.
