Se describen mezclas a base de agua, que compreden óxido de vanadio coloidal y un polímero sulfunatado disperso para impartir propiedades antiestáticas a revestimientos sobre un sustrato y artículos de autosoporte. El óxido de vanadio coloidal preferido es el derivado alcóxido y proporciona óxido de vanadio son típicamente de +4 y +5. Los sulfopolímeros preferidos incluyen sulfopoliésteres, sulfopoliuretanos, sulfopoliuretanos/ureas, sulfopoliesterpolioles, y sulfopolioles. También se describen estructuras compuestas antiestáticas, que comprenden óxido de vanadio coloidal y un sulfopolímero. 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.
