Abstract
Introduction. The article discusses the thermochemical properties of the composition of silver nanoparticles functionalized by the β-oligosaccharide clathrate complex of cytisine and its O,Odimethylphosphate derivatives. Methodology. Thermogravimetric and differential thermogravimetric analyses were used to obtain data on the kinetics of thermal decomposition of the studied substrates, as well as their encapsulated complexes of inclusions modified with silver nanoparticles. Results and Discussion. Studies have been carried out on a scanning electron microscope aimed at analyzing the evolution of their structure under the influence of various temperature conditions. Energy profiles of the processes of destruction of clathrate molecules have been obtained. It is shown that the process of destruction of clathrate molecules begins in reactions with higher activation energy values and continues with a uniform decrease in Ea along the reaction path, which indicates a multi-stage process. The research results made it possible to identify the corresponding phase transformations of nanocompositions, as well as possible recrystallization processes and other changes occurring in the inclusion complexes as a result of annealing. Conclusion. The kinetic data obtained contribute to predicting the properties of the obtained compositions of silver nanoparticles functionalized by the β-oligosaccharide clathrate complex of cytisine and its phosphorous derivative under long-term storage conditions and searching for optimal ways to stabilize them.
