Mechanical Properties of Polyacrylic Acid - Polyvinyl Alcohol Hydrogels at Compression and Extension

摘要

Cylinder and ring shaped samples of hydrogels were prepared by polymerization of acrylic acid in the solution of polyvinyl alcohol. The swelling degree and mechanical properties of the hydrogels were determined. The two-components hydrogels are characterized by a higher breaking strength and elasticity than the polyacrylic acid gels. It was found that the hydrogels demostrate the electromechanical response.
