Abstract

A composite textile is provided. The composite textile includes a textile substrate and a thermal material layer formed on the textile substrate. The thermal material layer includes a nanocomposite powder. The nanocomposite powder is composed of a pyrrolidone-containing polymer and an inorganic particle. The pyrrolidone-containing polymer is polyvinylpyrrolidone, a derivative of polyvinylpyrrolidone or a combination thereof. The inorganic particle is a metal oxide composed of a first metal M^A, a doping metal M^B and oxygen. The inorganic particle makes up 62.5-99.9 wt. % of the nanocomposite powder.
