Impact of Magnesium Salt on the Mechanical and Thermal Properties of Poly(vinyl alcohol)

The effects of magnesium salts with various anion species on the structure and properties of a poly(vinyl alcohol) (PVA) film were studied. The glass transition temperature of the PVA film increased following the addition of a magnesium salt. Furthermore, the salt greatly enhanced the modulus and yi...
