摘要: 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.

摘要: The present invention relates to a method of preparing reduced graphene oxide, incorporation of the reduced graphene oxide into polyisoprene latex to provide a polyisoprene latex graphene composite and elastomeric articles prepared using the polyisoprene latex-graphene composite. In particular, the reduction of graphene oxide is accomplished without the use of strong reducing agents and organic solvents and incorporation of the reduced graphene oxide into polyisoprene latex is accomplished using room temperature latex mixing method or hot maturation. The resultant composite exhibits good colloid stability and polyisoprene latex films produced from the composite exhibit good mechanical properties with improved ageing resistance.

摘要: A composition for manufacturing a polyurethane foam with a low content of volatile organic compounds such as acetaldehyde, and a method of manufacturing a polyurethane foam using the same are disclosed. The composition for manufacturing the polyurethane foam includes a polyol composition having a polypropylene glycol content of 0.1 ppm or less and a propylene oxide content of 16 ppm or less, isocyanate, and a volatile organic compound (VOC) reducing agent. The method for manufacturing the polyurethane foam includes adding raw materials to a reactor to polymerize a polyol composition, removing impurities from the reactor; and obtaining the polyurethane foam from reactants from which the impurities are removed.
