Structural Analysis of Foam by Small-angle Neutron Scattering

Abstract

Small-angle neutron scattering (SANS) is an effective technique for studying the ever-changing structure of foam. Recently, the microstructures of the foams formed by the amino acid-type novel surfactant and homogeneous EO-type surfactant with multi-branched double chains were investigated by using SANS. The information such as the size of the foam film, the presence of micelles in the foam film, and the average radius of the bubbles was clarified.
