Micro-structural evolution and biomineralization behavior of carbon nanofiber/bioactive glass composites induced by precursor aging time

Polyacrylonitrile electrospinning in combination with sol–gel method was applied to produce 58S bioactive glass (mol%: 58.0% SiO2-26.3% CaO-15.7% P2O5) containing carbon nanofibers (CNF/BG). The micro-structural evolution of BG in CNF composites and its effect on biomineralization behavior were systematically evaluated in relating to aging times of BG precursor sol–gel solution.
