NANOPOROUS BIOACTIVE GLASS WITH 3-D PORE STRUCTURE AND PREPARATION METHOD THEREOF

摘要

A nanoporous bioactive glass is provided to have excellent pore characteristics such as a large specific surface area and large pore volume, and be useful as drug delivery system materials, bone supporters, bone repair materials, and bone fillers. A method for preparing a nanoporous bioactive glass includes the steps of: (a) dissolving a block copolymer template in an alcohol-containing organic solvent to synthesize a block copolymer template solution; (b) mixing a silicon compound, a calcium compound, and a phosphor compound as elements to synthesize a bioactive glass solution; (c) adding the bioactive glass solution to the block copolymer template solution to obtain a precursor solution; and (d) drying the precursor solution.
