Thermally insulating aerogel composite fiber

Abstract

The present application provides a preparation method of an all-polymer aerogel composite fiber by compounding fiber material(s) with polymer-based micro-aerogel powder using a melting process, comprising of the following steps: (a) Weighing the materials to form the aerogel composite fibers, which should compose of 0.1-20% (w/w) polymer micro-aerogel powder and 80-99.9% (w/w) fiber material(s); (a) Mixing the polymer micro-aerogel powder and fiber material(s) to form a homogenized composite mixture; and (b) Heating the composite mixture up to the melting point of the fiber material(s) to disperse the polymer micro-aerogels throughout the molten fiber material(s), then extruded to form aerogel composite fibers.
