PRODUCTION AND POTENTIAL OF BIOACTIVE GLASS NANOFIBERS AS A NEXT-GENERATION BIOMATERIAL

摘要

A preparation method of bioactive glass nanofiber excellent in bioactivity and osteocyte function is provided to utilize BGNF as a novel bioactive implant material in fields of dentistry and orthopaedic hospital. A preparation method of bioactive glass nanofiber includes the steps of: mixing TEOS, calcium nitrate, and triethyl phosphate with a water-ethanol containing 0.01-1g of 0.1NHCl or 0.1NHNO3 to obtain a sol mixture; and agitating and incubating the sol mixture, adding a mixture of PVB and the sol at a ratio of 1:2-2:1 by weight, injecting 1-10ml of the sol mixture into a syringe and a metal collector for electric radiation under 0.5-2kV/cm DC field strength at the speed of 0.01-1ml/h, and heating the resulting nanofiber non-woven fabric at 600-900deg.C for 1-6 hours.
