The effect of silver nanparticles on the bactericidal and fungicidal properties of natural polymers-cellulose and collagen derivatives-was investigated. It was found that the treatment of films in a silver solution leads to a change in structure: ordering and compaction of microfibres. It is shown that the new materials, having fairly high bactericidal properties to different types of microorganism, are non-toxic and risk-free to humans and the environment.
Reported is an attempt to attain orientation of macromolecules during extrusion of films of cellulose derivatives that led to the liquid-crystalline state of a polymer and resulted in enhanced film strength.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
