Method of production of nanopartu00cdculas polimu00c9ricas with fullerenes encapsulated for application in optical sensors of temperature and content of oxygen molecular

摘要

Describes a method of produu00c7 & the rianopartu00cdculas and micropartu00cdculas polimu00c9ricas with fullerenes encapsulated but not covalently linked to the polu00cdmero. The nanopartu00cdculas containing fullerenes are synthesized by the polymerization process in mini emulsion.The particles function as temperature sensors (in vacuum or with molecular oxygen concentration of zero) or as sensors of content of molecular oxygen (for concentrations below the residual oxygen molecular, 700 parts per million in volume)Through variation of intensity (with or without an internal standard calibration internal fluorescent) or of the life time of fluorescu00cancia of fullerenes.Both the primary and the particulate nanopartu00cdculas nu00dacleo crown obtained from these can be used directly in fluorescu00cancia microscopy, deposited between two films polu00cdmu00c9ricos, or used to produce films or coatings.
