Composite hydrogels
Blechová, Dominika ; Smilek, Jiří (referee) ; Venerová, Tereza (advisor)
The content of this bachelor's thesis is research on the topic of composite hydrogels and subsequent research on the rheological properties of prepared hydrogels from the polysaccharide – Gellan, as well as the determination of the properties of hydrogels with the addition of two types of particles – IPA vesicles and a mixture of hydroxyapatite and calcium sulfate particles obtained by the breakdown of PerOssal pellets (PO particles). Hydrogels are prepared with three different concentrations of Gellan – 1%, 1.5% and 2%. The properties of hydrogels prepared in this way were determined using frequency and mainly amplitude tests. Furthermore, two different methods of applying the sample to the measuring plate of the rheometer were compared. The commonly used method of slicing the sample has been replaced by injection application. The injected samples were measured, the results evaluated and compared with the results of the gels applied by slicing.
