CONDUCTIVE POLYMERIC COMPOSITION AND METHOD FOR PREPARING THE CONDUCTIVE POLYMERIC COMPOSITION

The invention provides a composition for a conductive polymeric material suitable for the production of electrodes for recording electrophysiological signals, such as electrocardiogram (EGG), electromyogram (EMG), electroencephalogram (EEG), etc and signals related to the impedance variation of the body or skin, both deriving from active and passive measures (for example, breathing, electrodermal response, etc.). For this purpose a formulation containing FEDOT and ionic liquids has been developed. The formulation according to the invention can be used generically in the context of detecting bioelectric signals and can be applied on wearable items, in particular in fabric, such as for example garments of different shapes, so as to be in direct contact with the areas of the body subject to detection. The artifacts include diving artefacts, such as watertight suits, and for water sports and submarine surveys, artifacts used in the medical and health sector such as plasters, elastic support bands and adhesive support bands and textile articles, including special fabrics such as bioceramics.

Anionic electrochemical compressor and refrigeration system employing same
11339996 · 2022-05-24 ·

An electrochemical compressor utilizes an anion conducting layer disposed between an anode and a cathode for transporting a working fluid. The working fluid may include carbon dioxide that is dissolved in water and is partially converted to carbonic acid that is equilibrium with bicarbonate anion. An electrical potential across the anode and cathode creates a pH gradient that drives the bicarbonate anion across the anion conducting layer to the cathode, wherein it is reformed into carbon dioxide. Therefore, carbon dioxide is pumped across the anion conducting layer. The compressor may be part of a refrigeration system that pumps the working fluid in a closed loop through a condenser and an evaporator.

Phosphonated polymers, and methods of production thereof, for use as polymer electrolyte membranes (PEMs) and/or catalyst ionomeric binders for electrodes in PEM fuel cells

The present disclosure provides phosphonated polymers that can be used, for example, as polymer electrolyte membranes (PEMs) and/or catalyst ionomeric binders for electrodes in PEM fuel cells, and more particularly for high-temperature PEM fuel cells. High-temperature PEM fuel cells that use phosphonated polymers of the present disclosure suffer from reduced or no acid leaching because, in at least some examples, phosphonic acid moieties are covalently bound to the backbone of the polymers. A phosphonated polymer include a backbone having one or more aromatic monomers, with each aromatic monomer having one or more phosphonic acid groups. A phosphonic acid group may include phosphonic acid or a functional group that is hydrolysable into phosphonic acid.

Methods of making solid-state semiconducting films. The methods include forming a mixture by mixing at least two monomers in a pre-determined proportion such that at least one of the at least two monomers contains at least one non-conjugation spacer. Polymerization of the mixture is achieved by reacting the monomers with one another resulting in a solid state polymer which is then purified. The purified solid state polymer is dissolved in an organic solvent to form a homogenous solution which is then deposited onto a substrate, forming a solid-state semiconducting film by evaporating the solvent. Alternatively, the purified solid state polymer is deposited onto a substrate and heated to form a liquid melt, and cooling the liquid melt results in a solid state semiconducting thin film. Also, films comprising a semiconducting polymer composition containing a minimum of one non-conjugation spacer and devices comprising such films.
