Formulating polymer solutions to stabilise polymeric foams

DOI

Polyurethane foams (PUF) are commonly prepared by mixing Pluronic type copolymers and isocyanate reactive monomers in the presence of additives e.g. catalysts, blowing agents and surfactant. The physical properties of the resultant foam (cell morphology and size, capacity for water adsorption, thermal insulation etc) are strongly dependant on the surfactant blend employed in the foam formulation. Our previous work has shown that novel, stacked structures form at the interface. Here, we wish to extend the interfacial study of these interesting materials, and the role that the formulating surfactant blends play in defining the detail in this novel structure. The over-arching aim of this PhD project is to better understand the role of the surfactant in stabilizing the foam structure and its perturbation on inclusion of novel additives, both small molecule and particulate in nature.
