Preparation and Characterisation of Polyelectrolyte Complexes in the System Dextran-Surfactant
 Klímová, Eliška ; Krouská, Jitka (referee) ; Kalina, Michal (advisor)
This bachelor thesis deals with the study on preparation and characterization of the polyelectrolyte complex formation in the dextran-surfactant system. The aim of the thesis was the investigation of the influence of the ionic strenght on the formation of the interactions in the studied system. For these purposes, components having opposite charges (DEAE-dextran hydrochloride and anion-active sodium dodecyl sulphate) were selected. For individual measurements mainly the methods of light scattering, dynamic and electrophoretic light scattering in particular, have been used. In the thesis have been studied interactions and aggregation concentrations of individual components having the potential to form polyelectrolyte complexes. It was verified in all the studied samples, by measuring the intensity of scattered light and the size of Z-diameter of particles, that the increase in sizes of particles is caused by the formation of these complexes. There were also measured additional characteristicts of the system such as pH or conductivity. Their dependences provide comprehensive view on the formation of complexes in studied system and can be utilized for other measurements and possible future applications, especially for purposes in medical applications.
