DESCRIPTION
General description
PVP has biocompatibility, low toxicity, adhesive characteristics, complexing stability, relatively inert behavior, and is resistant to thermal degradation. It is readily prepared by the polymerization of N-vinyl-2-pyrrolidone or by Reppe synthesis technique.[1]
Application
PVP is used as a carrying polymer for electrospinning continuous titania nanofibers[1][2] and zirconium tungstate ultra thin fibers.[3] PVP may be used as one of the constituents in the synthesis of silver nanocubes. It serves as a reducing agent[4] and colloidal stabilizer[5] in the synthesis of palladium nanobars,[4][5] triangular and nanoplates.[6] It may also used as a capping agent in the synthesis of silver nanospheres,[7]gold nanoframes.General applications pf PVP are: in pharmaceutical, food, beverage, cosmetic, toiletry and photographic industries.
Other Notes
Polyvinylpyrrolidone is a component of Denhardt′s Solution and is included at a concentration of 1% (w/v) in the standard 50X stock solution.
