聚乙烯醇

Polyvinyl alcohol is used as a biological reagent to test the dispersion of zinc oxide nanoparticles. It is an effective protein resistant material and is used to stabilize gold colloids of diameter 3-8nm. It is used as an emulsion polymerization aid to make polyvinyl acetate, as a protective colloid, as a film used in the water transfer printing process, as a surfactant for the formation of polymer encapsulated nanobeads, as an embolization agent in medical procedures and as a fixative for specimen collection.
