Abstract
Embodiments of the invention include methods for making silica fiber mats useful for treatment of animal wounds and tissue, as well as for other applications in industry. The fiber mats are formed via electrospinning of a sol gel produced with a silicon alkoxide reagent, such as tetraethyl ortho silicate, alcohol solvent, and an acid catalyst.
Claims29
A method for making a silica fiber composition, comprising:
- preparing a sol that contains 70% to 90% tetraethyl orthosilicate (TEOS) by weight, 12% to 25% ethanol by weight, 1% to 10% water by weight, and an acid catalyst;
- transitioning the sol to a sol-gel for 2 to 7 days under conditions where humidity is within the range of 40% to 80%, and the temperature is within the range of 50 to 90° F.;
- and
- electrospinning the sol-gel into a silica fiber mat.
