Abstract

This chapter outlines factors that may affect latex coalescence as well as provides fundamental principles of spectroscopic probes allowing multi-dimensional analysis of surfaces and interfaces. Using attenuated total reflectance (ATR), photoacousitc (PA), and infrared imaging Fourier transform infrared spectroscopy (FT-IR) these studies show that surfactant stratification can be affected by numerous factors such as surfactant-copolymer interactions, substrate surface tensions, particle and suspension composition, coalescence and glass transition temperatures, and the particle size. Furthermore, the presence of additives also affects film properties due to a non-homogeneous distribution of individual latex components. This process is amplified by exposure to elevated temperatures and enhanced relative humidity.
