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 ...
Sulfonated polystyrene-block-poly(ethylene-ran-butylene)-block-polystyrene (SPSPB) was used as a polymer matrix to create polymeric nanocomposites using graphite (G) and graphite-polyoxometalate (G-POM) as fillers. It was found that the nanocomposites had higher thermal and electrical conductivities than SPSPB alone, and that both the thermal and the electrical conductivity increased with increasing filler concentration. At all filler contents tested, the SPSPB/G-POM had both a higher thermal conductivity and a higher electrical ...
The authors present a novel method for the preparation of highly porous tannin-based meringues by shear mechanical mixing of tannin, hexamine, and Kolliphore® ELP in water. The liquid foam was then cured in an oven at 85oC for 24 hours. The resultant solid foams were found to be homogeneous and they were also found to have similar thermal conductivity and other physical properties to tannin-based foams prepared by more traditional methods....
The authors have investigated the use of silver nanomaterials as a filler in epoxy resin in an effort to identify a composite resin with a high thermal conductivity for application as a thermal interface material. It was determined that the addition of silver nanoparticle and silver nanowires both increased the thermal conductivity of the resin, but the silver nanowires caused a much more drastic increase. It was found that by ...
The authors have dispersed mesoporous silica (MPSiO2) nanoparticles in water and determined the thermal conductivity for each of the resulting nanofluids. It was determined that the thermal conductivity of the nanofluid was greater than that of water, so these nanofluids have potential for use in heat exchanger applications....
