Rocks have good chemical and thermal properties, which are widely distributed in mountainous areas and contain a great number of chemical elements. Weathered rock powders were used as an additive in an electrospun solution to fabricate rock powder-based nanofibers, and the morphology and thermal property of nanofibers were studied. The results revealed that the rock powder was the most economical approach to fabrication of nanofibers with excellent thermal property and high hydrophilicity. This paper sheds a light on rock powder-based nano-fibers with well-defined characteristics for advanced applications for high temperature filtration and absorption, fire prevention and others.
