Inorganic and hybrid tubes prepared by calcining natural fibrous materials

摘要

PURPOSE: A manufacturing method of a mixed tube is characterized by using a fiber type natural substance like hair, fur, wool, cotton yarn and cobweb or an inorganic tube got from fiber manufactured out of the natural substance and burning the natural substance at proper temperature. CONSTITUTION: The mixed tube is obtained by the steps of: burning the fiber type natural substance at proper temperature to get the tube; soaking the tube into polyolefine monomer like styrene and methacrylate and heating the soaked tube in air to get the polymer/inorganic mixed tube; treating the tube with a polymer solution like polystyrene or poly(methyl methacrylate) to get the polymer/inorganic mixed tube; or treating the tube with a silver nitrate solution, drying the tube and radiating ultraviolet to the tube to get the tube containing silver.
