d. Under theACIDcatalysis, polyvinyl alcohol can be condensed with formaldehyde, butyraldehyde, Glyoxal or other aldehydes to produce polyvinyl alcohol acetals (such as PVAF, PVB) with stronger water resistance, adhesion and mechanical strength, which are widely used in building construction, coating...
Polyvinyl alcohol (PVA) is a linear synthetic polymer produced via partial or full hydrolysis of polyvinyl acetate to remove the acetate groups. The amount of hydroxylation determines the physical characteristics, chemical properties, and mechanical properties of the PVA[1]. The resulting PVA polymer...
Properties of polyvinyl alcohol PVA is an odorless white flake, flocculent or powdery solid. It is soluble in water, slightly soluble in dimethyl sulfoxide, but insoluble in gasoline, kerosene, vegetable oil, benzene, toluene, dichloroethane, carbon tetrachloride, acetone, ethyl acetate, methanol, et...
A solid polymer electrolyte with a poly (vinyl-alcohol) (PVA) matrix and a mixture of H 3PW 12O 40 (PWA) and H 4SiW 12O 40 (SiWA) as proton conductor was developed. The proton conductivity of this polymer electrolyte reached 0.013 scm 1 at room temperature with a very low activation...
This article explores the recent advancements in the numerous applications of polyvinyl alcohol (PVA) and its various composites.
