| titleOfInvention | Synthesis and incorporation process of silver nanoparticles in hydrophilic polymer matrices |
| abstract | Synthesis process and incorporation of silver nanoparticles in hydrophilic polymer matrices and use of silver nanoparticles This patent application refers to a new process of synthesis of a nanostructured complex of silver (npag) and chitosan (npag: qs) nanoparticles and the subsequent incorporation thereof in hydrophilic polymer matrices. Nanocomplexes are obtained in one step by reducing their ions in aqueous solution by the combined action of citric acid and chitosan (qs). With this new synthesis route using two reducers together, it is possible to inhibit the degradation of qs during synthesis, reduce synthesis time, as well as achieve npag with a smaller distribution and size with the use of environmentally friendly reducers. after synthesis the powder nanocomposite, npag: qs. This powder can be redissolved in an acidic aqueous solution together with a hydrophilic polymer such as polyvinyl alcohol (pva). As a final product, a plastic film with bactericidal properties is obtained due to the action of both npag and qs. |
