| Abstract: | The surface-modified dental barium glass with silane coupling reagent KH-570 was studied. The prepared samples before and after modification were characterized by static precipitation, angle of contact, transmission electron microscopy, X-ray photoelectron spectroscopy, Fourier transform infrared ray, and thermo-gravimetric analysis. Research showed that the KH-570 was bound on the surface of barium glass, a firm chemical bonding of KH-570 to barium glass and an organic layer was formed, and the maximum mass fraction of KH-570 coated on the barium glass surface measured was about 2.86%. The surface performance of modified barium glass changed from hydrophilic to hydrophobic. Mechanical tests revealed that the mechanical properties of composite resin filled by KH-570 modified barium glass improved simultaneously. |
