MEZCLAS DE BASE ACUOSA, COMPRENDIENDO OXIDO DE VANADIO COLOIDAL Y UN POLIMERO SULFONATADO DISPERSO, IMPARTEN PROPIEDADES A REVESTIMIENTOS SOBRE ARTICULOS DE SUSTRATOS Y DE AUTOSOPORTE. EL OXIDO DE VANADIO COLOIDAL PREFERENTE ES DERIVADO ALCOXIDO, Y PROPORCIONA OXIDO DE VANADIO DE VALENCIA MIXTA MEZCLADOS, DONDE LOS IONES DE VANADIO SON TIPICAMENTE +4 Y +5. LOS SULFOPOLIMEROS PREFERENTES INCLUYEN SULFOPOLIESTERES, SULFOPOLIURETANOS, SULFOPOLIURETANOS/UREAS, POLIOLES DE SULFOPOLIESTERES Y SULFOPOLIOLES. TAMBIEN SE DESCRIBEN ESTRUCTURAS COMPUESTAS ANTIESTATICAS, COMPRENDIENDO OXIDO DE VANADIO COLOIDAL Y UN SULFOPOLIMERO. Aqueous-based mixtures comprising colloidal vanadium oxide and a dispersed sulfonated polymer impart antistatic properties to coatings on a substrate and to self-supporting articles. The preferred colloidal vanadium oxide is alkoxide derived and provides mixed valence vanadium oxide wherein the vanadium ions are typically +4 and +5. Preferred sulfopolymers include sulfopolyesters, sulfopolyurethanes, sulfopolyurethanes/ureas, sulfopolyester polyols, and sulfopolyols. Antistatic composite structures comprising colloidal vanadium oxide and a sulfopolymer are also disclosed.
