Modification of nonwoven fabric by silver nanoparticles in a cellulose matrix

Popis výsledku v původním jazyce

CMC is a hydrophylic polymer with huge potential in medical applications. An increasingly common application is the use of silver nanoparticles for antimicrobial coatings, wound dressings, and biomedical devices. This study presents a preparation of special structures containing nanoparitcles of silver in a polymeric matrix, which is able to absorb an extreme quantity of water. During the reaction of silver ions with CMC, a slightly soluble silver salt of CMC is formed; that is why it is necessary to add AgNO3 slowly with vigorous stirring. The reducing agent in this case is the COOH group in CMC. Alternatively, UV radiation can be used to prepare metallic silver. The resulting nanoparticles of silver are mechanically fixed the in mass of CMC. CMC is then stabilised by heating, which leads to crosslinking between CMC and the partial loss of carboxylic groups. The prepared structure will then used for special medical applications. The antibacterial properties of the prepared samples wer
