Abstract[English]
The matter of the invention is a filter material that is made of a nanofibrous layer of polyvinylalcohol, a non-woven fabric made of polyvinylalcohol is used as a carrier of our filter material, which creates the overall filter product. The filter material is the only synthetic polymer that has a chain made of carbon-carbon bonds and is degradable, whereas H2O and CO2 are the degradation products. Physico-chemical properties, minimal toxicity and biodegradability predetermine the material not only for use in the biomedical and pharmaceutical industries. The filter material, including the nanofibrous layer, meets ecological requirements regarding the environment, their subsequent disposal does not burden the environment.[French]
La présente invention concerne un matériau filtrant qui est constitué d’une couche nanofibreuse d’alcool polyvinylique, un tissu non tissé en alcool polyvinylique est utilisé en tant que support de notre matériau filtrant, de façon à former le produit de filtre global. Le matériau filtrant est le seul polymère synthétique qui comporte une chaîne constituée de liaisons carbone-carbone et est dégradable, tandis que H2O et CO2 sont les produits de dégradation. Les propriétés physico-chimiques, la toxicité minimale et la biodégradabilité prédéfinissent le matériau non seulement pour utilisation dans les industries biomédicale et pharmaceutique. Le matériau filtrant, comprenant la couche nanofibreuse, satisfait aux exigences écologiques vis-à-vis de l’environnement, leur élimination ultérieure n’étant pas un fardeau pas l’environnement.
