Andriianova M. Synthesis and investigation properties of polymer quaternary ammonium salts for ion-conducting materials

Object – ion-conducting cross-linked ammonium interpolymer complex (АIPC). Purpose – study of synthesis of ion-conducting AIPC and research the influence of their structural characteristics on ionic conductivity, thermal stability and physical-mechanical characteristics. Methods – gravimetric and thermogravimetric analysis, wide- and small-angle X-ray scattering, IR- spectroscopy, pyrolitic mas-spectrometry, impedans spectroscopy. Results – the new ion-conducting film materials based on polymeric quaternary ammonium salts of class cross-linked ammonium interpolymer complexes were obtained by joint condensation polymer derivatives of epichlorohydrin and poly-4-vynylpyridine, and modification by low-molecular amines and organic or organosilicon chloromethyl derivatives. Show that the AIPC was characterized by partial fractal aggregation of internal structure, specificity that significant influences on the processes of ion transfer in the bulk polymer matrix. Novelty - the proton-conducting film materials based on cross-linked complexes AIPC-H3PO4 which provide high conductivity were obtained; in the first time is offered use film AIPC as a polymeric electrolyte matrix in the lithium chemical power sources. Introduction – materials of dissertation give of possibility of obtaining of new ion-conducting materials for use as membranes and electrolyte in perspective electrochemical devices: fuel cell, sensors, lithium chemical power sources and other. A sphere of the use is chemical industry perspective electrochemical devices for modern techniques.
