Adhesion of the Hydrogels based on Poly(vinylalcohol)
Přibyl, Jiří ; Trudičová, Monika (referee) ; Kalina, Michal (advisor)
This bachelor thesis was focused on the study of adhesion properties of hydrogels based on polyvinyl alcohol using a rheometer. The used hydrogels were divided into three groups, physical, chemical, and modified with starch, PEG or gelatin. Subsequently, the adhesion properties of the hydrogels were determined using a pull off test measured on a rheometer. From the experimental results, the dependences of the adhesion properties on various parameters such as concentration, molecular weight, freezing / thawing process, amount of glutaraldehyde addition and on the type and ratio of added additive were determined. From the following results, it was found that starch is suitable as an additive for increasing the adhesion properties, and on the other side, PEG can be used to reduce the adhesion properties.
