Open dodecahedral pores in PU foam
As we reported last week, in their recent paper in Journal of Physics D: Applied Physics, authors Dr Javier Pinto et al presented this week’s Image of the Week: an SEM micrograph of open dodecahedral pores with high connectivity in a polyurethane foam, in which each pore is connected with all the surrounding pores.
The authors state that an interconnected structure, which water can easily flow through, is key to creating a highly effective mechanical sponge for clearing oil spills and potentially other contaminants such as heavy metals or pesticides.
