Currently, the bioglass is object of study for its ability to be biocompatible with
the tissues of the human body, reason why have been made different
formulations for application as functional biomaterial in the development of
implantable devices and of physiological functions. In the present research,
bioglass (BG) was synthesized through the sol-gel technique beginning with
tetraethylorthosilicate (TEOS). The obtained biomaterial was kept in a sealed
glass bottle at room temperature for 10 days, after this time it remained at 70 °
C for 3 days, finally a thermal treatment was carried out at 120 ° C for 2 days.
The resulting bioglass was mixed with polylactic polymer (PLA) 30% and 70% by
weight (BG 70%- PLA 30%) (BG 30% - PLA 70%). The resulting sample was
characterized by infrared spectroscopy by Fourier transform FTIR and Scanning
Electron Microscopy. Thin films of different percentages of composite material
BG-PLA were developed to perform potentiostatic electrochemical tests where
the degradation behavior will be evaluated in Hanks saline solution and
simulated body fluid. After the evaluations, an excellent resistance to
degradation was observed.
