Process for the deposition of sensors on a porous substrate

摘要

The process of fabricating a textile article, comprises defining areas for grafting on a plane porous support (3) of the article, applying a polymerizable liquid resin (1) on a side of the porous support by seriography, polymerizing the resin, impregnating the porous support using a solution or dispersion of molecular sensors, fixing the molecular sensors on the support, and retreating the resin. Some of the areas are grafted by molecular sensors, and the rest are free from grafting. The liquid resin is polymerizable on the grafted excluded zone. The porous support is a woven material. The process of fabricating a textile article, comprises defining areas for grafting on a plane porous support (3) of the article, applying a polymerizable liquid resin (1) on a side of the porous support by seriography, polymerizing the resin, impregnating the porous support using a solution or dispersion of molecular sensors, fixing the molecular sensors on the support, and retreating the resin. Some of the areas are grafted by molecular sensors, and the rest are free from grafting. The liquid resin is polymerizable on the grafted excluded zone. The porous support is a woven material, a non-woven material and a foam with cell opening. The resin is ink and varnish used for screen printing on textiles, a thixotropic resin curable under UV light, photosensitive resin used in microelectronics, and thixotropic adhesives. The process further includes depositing polypyrrole/polyaramide on the porous support, soaking the resin in a solution of tin chloride-palladium chloride, activating by chemisorption of palladium or platinum and soaking in a solution of copper (Cu(II)), reducing the metallic copper, treating the resin on the support using chromic acid and sulfuric acid, reducing the chromium (Cr(VI)) ion with glyoxal, glyoxylic acid, hydrazine, hydroxylamine, sodium hydrosulfite, sodium bisulfite and/or tin (II) chloride, activating tin chloride and/or palladium by pre-immersion of hydrochloric acid and impregnation of copper. The support comprises a function of silane in which compatible biological or chemical elements are fixed. The resin is soaked in a successive bath of solutions including palladium, tin and copper sulfate and then in metal molecules such as gold, silver and platinum.
