Popis

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.

Application

PVP is used as a carrying polymer for electrospinning continuous titania nanofibers and zirconium tungstate ultra thin fibers. PVP may be used as one of the constituents in the synthesis of silver nanocubes. It serves as a reducing agent and colloidal stabilizer in the synthesis of palladium nanobars,
triangular and nanoplates. It may also used as a capping agent in the synthesis of silver nanospheres,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.
