AB - A simple kitchen mixer and skills to whip cream can be useful to manufacture highly functional polymer foams with control over their structures. In the 1930s, researchers began to whip or inject gas into monomers or polymer suspensions to produce liquid foams, which served as templates to be solidified to polymer foams. Besides the “simplicity” of the foam templating method, its actual advantage as compared to widely used blown polymer foams is the nonessential need of physical and chemical blowing agents, resulting in a lower raw material cost, less involved chemistry, lower safety and health risk during production and a reduced impact on the environment. Compared to other templating methods, such as emulsion templating, which require sacrificial materials serving as templates, liquid foams with bubbles as templates are superior from a material processing perspective because they require no further materials or energy for template removal. A challenging step in foam templating is to create a stable liquid foam containing building blocks for subsequent solidification; when using air as an internal phase, the choice of materials in the liquid phase to create a stable colloidal system is restricted. In this chapter, we review previous work on foam templating with a focus on porous materials produced therefrom, including macroporous thermoplastic, thermosetting polymers, hydrogels, biobased materials and polymer composites. We aim to show that foam templating is a greener than any other templating methods, such as emulsion templating and particulate leaching, and versatile foaming process and to encourage researchers to conduct both fundamental and applied research to push the boundaries of this technology further.
