ИЗУЧЕНИЕ СВОЙСТВ СОПОЛИМЕРНОГО ПОКРЫТИЯ МЕТОДОМ ЭЛЕКТРОХИМИЧЕСКОЙ ИМПЕДАНСНОЙ СПЕКТРОСКОПИИ

В данной работе методом импедансной спектроскопии исследовано защитное свойство электрохимически синтезированного сополимера поли (анилин-о-анизиндина) (ПАОА) в 3,5% растворе NaCl при различной времени экспозиции. На основе диаграмм Найквиста расчитаны степень защиты, степень поглощения воды и толщина сополимерного покрытия. Обнаружено, что значения защитных свойств не подчиняются определенной закономерности из-за плохой адгезии покрытия, синтезированного из раствора щавелевой кислоты. По результатом расчётов после 120-минутного погружения покрытия в агрессивную среду, были получены следующие значения: Z =78,95%, % = 33,80 и d = 11,00 нм.
