Антикоррозионная активность амфифила фосфоновой кислоты в самоорганизующемся молекулярном слое

Целью настоящей статьи было продемонстрировать повышение коррозионной стойкости двух нержавеющих сталей после нанесения нанослоев. Вопросы, на которые мы хотели ответить, заключались в следующем: как время самоорганизующегося осаждения влияет на компактность нанослоев и на то, как состав стали влияет на осаждение нанопленки, ее компактность и антикоррозийные свойства. Чтобы ответить на эти вопросы, были приготовлены методом погружения самоорганизующиеся молекулярные слои; нанослои характеризовались величиной смачиваемости водой и образцы двух различных нержавеющих сталей с нанопленками и без них подвергались воздействию агрессивных сред (раствор натрий хлорида). Влияние хлорид–ионов на твердые поверхности визуализировали  методом  атомной  силовой  микроскопии  и  характеризуется параметрами шероховатости. Антикоррозийная эффективность вызвано составом поверхности стали, а также различной самоорганизующейся адсорбцией. Время было объяснено экспериментальными данными.
