In 2021 a Czech company launched its novel, patented method of copper plating of low weight flat textile materials. The method is applicable on various materials, primarily polyesters, nevertheless, there is also experience with copper plating of non-woven, woven, synthetic, natural, bi-component fabrics based on polypropylene, viscose, glass, polyamide, too. Method of plating (continuous roll-to-roll process, maximal material´s width: 110 cm). Combination of: - Chemical (electroless) plating and - Electroplating. Additional optional treatments: - Hydrophilization (physical and/or chemical pre-treatment) - Surface inhibition and/or impregnation „Roll to roll“ production process guarantees a homogeneous, standardized product (metallized in whole 3D structure in full width of the original substrate/based fabric) and provides an assurance of consistent high quality. Treated materials deliver new properties to the final product that can be used in various industries like: - Aerospace (novel composites, electrostatic protection, lighting strike protection) - Automotive (EMF shielding, heat reflectivity, substitution of fragile aluminum foils, reduction of components´ weight and volume – insulative materials) - Cables (especially electromagnetic shielding properties) - Construction (EMF shielding, weight and volume savings, antimicrobial protection of wooden construction materials) - Electronics (EMF shielding) - Filters for air-conditioning (antimicrobial protection) - ICT (EMF shielding) - Military (EMF shielding, IR reflection – camouflage) - Packaging (for sensitive electronics), - Textiles (EMF shielding, thermoelectric heating, wearables) - Etc. The novel method adds materials novel properties: - Electromagnetic radiation shielding - High conductivity (electric, heat) - Heating by internal resistance - Reflection of infrared radiation (60% - 80% of IR is reflected, 4-15μm) - Antimicrobial efficiency (copper is naturally antimicrobial) … while coated fabrics preserve their original properties, e.g.: - Low weight - Flexibility - Tensile strength - Breathability (moisture vapour and air permeability) Treated materials can be easily cut, welded, soldered, but they are also well as suited for further processing (e.g. by lamination, pressuring processes). The company seeks partners interested in deliveries of plated fabrics designed for their applications under commercial agreement with technical assistance. Testing of metallization and functionality on partner´s materials is available (lab and pilot scale).
