Abstract: The authors have prepared highly porous, monolithic, carbon polymerised high internal phase emulsions (carboHIPEs) using tannins as the base material. This material was considered to be one of the most environmentally friendly carboHIPEs to have been prepared based on the fact that it is almost entirely composed of plant-derived chemicals. It was determined that in terms of porosity and mechanical properties, these carboHIPEs compared well with others that had been prepared using other methods, but the cell and window sizes were larger, and the surface area was lower. In response to this, the authors have stated that a broader range of carboHIPEs can be obtained from tannin using different reaction conditions and different materials. It was determined that the carboHIPEs prepared had potential applications as catalyst supports, filtration media, adsorbents, and thermal insulators due to their small pores, favourable mechanical properties, and low thermal conductivity.
