Non-destructive chracterization of hydrogels

Hydrogels were prepared by a freeze-thawing procedure, and investigations made on the effect of the number of freezing-thawing cycles as well as on the content of hyaluronic acid in the gels on the mechanical properties. The bulk elastic modulus was measured by the ultrasonic pulse-echo method. Ultr...

Summary:Hydrogels were prepared by a freeze-thawing procedure, and investigations made on the effect of the number of freezing-thawing cycles as well as on the content of hyaluronic acid in the gels on the mechanical properties. The bulk elastic modulus was measured by the ultrasonic pulse-echo method. Ultrasonic attenuation measurements were also performed using a scanning laser acoustic microscope (SLAM) to show defects and density changes in the hydrogels.
