Self-regulation of foam volume and bubble size during foaming via shear mixing

摘要

Graphical abstractDisplay OmittedHighlights?The process of air entrapment in a shear mixer stops when the foam reaches a certain critical shear stress.?For high surface modulus surfactants, this stress is reached at lower air fraction and with smaller bubbles.?For surfactants with mobile surfaces, more voluminous foam with larger bubbles is formed.?Dynamic surface tension (DST) affects the foaming rate only.?The air volume fraction and bubble size in the final foam are not affected by DST.Abstract展开▼
