“Barrier kinetics of adsorption–desorption of alcohol monolayers on water under constant surface tension”

Soft Matter, 2019, 15, 1730–1746; IF 3.399; Q1

В предходни изследвания, свързани с разтворимостта на монослоеве от слаборазтворими повърхностно активни вещества, са получени резултати, които са в противоречие с широко възприетата в литературата  представа за дифузионно лимитиран процес на десорбция. В тази връзка сме провели систематично изследване на разтворимостта на монослоеве от додеканол и деканол в широк температурен интервал (от 10-30ᵒС). Експерименталните резултати са получени чрез комбинация от три различни метода: лангмюирова везна, тензиометър с профилен анализ и ядрено-магнитна спектроскопия (NMR). Направен е детайлен теоретичен анализ на получените данни. Резултатите ясно демонстрират наличието на енергетичен бариер в началните времена на процеса на десорбция. Получени са числени стойности на редица константи, характеризиращи процеса на разтворимост, като например характерно време за престой на молекула ПАВ на повърхността на монослоя (td), активиращата енергия на бариерния преход и др. Направено е обобщение под формата на схематична диаграма, демонстрираща различните механизми на десорбция, като функция на времето, конвекцията на ПАВ и температурата.
