Abstract:
1. A hybrid chemical sensor comprising a sensitive compound completely dispersed within a polyolefin matrix and encapsulated by a hybrid capsule obtained by sol-gel reaction, said hybrid capsule using siliceous alkoxides or titanium alkoxides, wherein at least one of said alkoxides is substituted with one or more alkyl chains, wherein the hybrid chemical sensor responds to the presence of amine and/or amide and/or oxide-reducing compounds, and/or vapor thereof by color change after being dispersed through the polyolefin matrix, and wherein the hybrid chemical sensor is incorporated into the polyolefin matrix by extrusion and without any loss in chemical characteristics during polyolefin processing, and is used as an indicator of conditions in a particular environment in contact with said hybrid chemical sensor.
