Characteristics as a blue clear appearance, viscous solution, odorless are some properties from Polyvinyl alcohol (APV), as a dry film it is clear transparent, shows high flexibility and it is a good insulator. This polymer does not contain double link then it does not have π orbital that permit an inherently conductivity when it is doped. However, can be doped with salts as nickel chloride hexahydrate NiCl26H2O constructing a good conductor polymer with a resistivity around 300Ω cm. This doped polymer shows high dependency to the oxygen molecule by its molecular form or its presence in the humidity of the atmosphere. If a high vacuum is applied in a reactor with the doped polymer the value of resistivity increases quickly. The material shows a light reduction of resistivity parameter when its temperature is increased. Finally the polymer doped maintains high flexibility opening new possibilities and applications.
