Foaming behavior of aqueous solutions containing hexadecyltrimethylammonium bromide and silica nanoparticles analysis of stability and interfacial properties

Abstract

Aqueous foams are considered as two phase fluids in which the gas bubbles are dispersed in the aqueous phase The bubbles are separated by interconnecting thin liquid films The liquid content is sufficiently high in wet foams whereas the same is usually small in dry foams Aqueous foams belong to an important class of engineering materials due to their numerous applications in industry and daily life such as floatation firefighting water treatment paints and coatings textile finishing enh
