Monodisperse polymer foams and characterization of foam structures

Part of:

Foams are usually described as a dispersion of gas bubbles in a liquid, whereas solid foams are generated by a transition from the liquid phase to a gel-like or solid phase. But the sometimes rather complex production processes for solid foams often result in foam morphologies where neither size nor connectivity of the foam pores is controlled. In order to realize mono- or polydisperse, open-pore polymer foams with stable and solid foam structures as templates for the production of metal foams, we achieved this transition by in-situ cross-linking of polymers in addition to surfactants, blowing agents, initiators or template particles. Varying the template parameters as well as the added poly- and monomers, initiators and the choice of activation processes (e.g. UV light or temperature) influence both the morphology and mechanical behaviour of the foams. By adjusting the aforementioned reaction conditions we set out to control and tune pore size, organization and connectivity. With the aim of developing novel biomaterials and metal foam templates, various large-pore polymer foams with different mechanical properties were produced depending on the foam matrix and processes for foam development.
