Abstract
Darbā ir veikta poli(ēter ētera ketona) sulfonēšana un ir iegūti paraugi ar dažādām sulfonēšanas pakāpēm, no kurām tika izgatavotas membrānas. Sulfonēšanas pakāpe tika noteikta ar titrēšanas metodi. Izmantojot impedances metodi, tika noteikta sulfonēta poli(ēter ētera ketona) membrānu elektrovadītspēja atkarībā no sulfonēšanas pakāpes. Membrānas tika analizētas ar rentgendifraktometrijas metodi un termogravimetrijas metodi.
In this study poly(ether ether ketone) was sulfonated and membranes with different degree of sulfonation were made and membranes with different degree of sulfonation were obtained. Titration method was used to determine the degree of sulfonation. Impedance method was used to determine electrical conductivity of sulfonated poly(ether ether ketone) membranes depending on different degree of sulfonation. Membranes were also analysed with X-ray diffractometry and thermogravimetric analysis.
