Аннотация
В данной работе были изучены коллоидные свойства лиофильной дисперсной системы V2O5 ∙ nH2O золя, полученной путем термолиза порошка V2O5 пероксидом водорода. Дисперсионная фаза существует в виде нанолистов. Оптимальное мольное соотношение V2O5 и H2O2 для синтеза золя составляет [1]:[30], а возможная концентрация V2O5 во всей коллоидной системе составляет от 0,3 до 1,6 мас.%. Существование наночастиц в этой дисперсной системе и диапазон pH, обеспечивающий стабильность золя, соответствуют фазовой диаграмме ванадия (V) в водной среде. Абсолютная величина дзета-потенциала частиц увеличивается с увеличением исходной концентрации при синтезе золя и уменьшением ионной силы дисперсионной среды. Фактор формы частицы, определяемый формулой Эйнштейна, имеет значение 9,608. По теории ДЛФО также были построены потенциальные кривые парного взаимодействия между наночастицами.
