New 92S6 mesoporous glass: Influence of surfactant carbon chain length on the structure, pore morphology and bioactivity

Abstract

International audienceThe main objective of the present work was to investigate the effect of surfactant chain length on the structure, porosity and bioactivity of 92S6 (92% SiO2, 6% CaO, and 2% P2O5 mol%) mesoporous sol-gel glasses. The aim was to provide a basis for controlling the porosity of the glass to obtain a control of bioactive behavior. A series of mesoporous bioactive glasses were synthesized using three different surfactants (C10H20BrN, C19H42BrN, C22H48BrN). Surfactant type dependence on the textural properties, particularly porosity and bioactivity were studied. Result indicate that the bioactivity factors were improved by a short surfactant carbon length

“…To enhance the functionality of bioglass, antibacterial agents are often added to the composition of glass systems. Among them, nano silver is the leading candidate because of its antibacterial ability [7][8]. The purpose of this work is to manufacture three-component SiO2 -CaO -P2O5 glass system doped with Ag using the modified sol-gel method.…”
