Rubber carbon black (CB)/rubbery epoxy (RE) and CB/silicone composites with different types, loadings, and silane functionalization of carbon black were prepared. These composites were investigated for their electrical conductivities, and their mechanical properties. The thermal conductivity of each composite was also determined using a thermal constants analyzer. It was determined that the incorporation of carbon black into the composites increased the thermal conductivity in all of the samples. ...
Graphite nanoplatelets were dispersed in varying quantities into a silicone matrix to form composite materials with higher thermal conductivities than the pure silicone matrix without sacrificing mechanical properties. It was found that the thermal conductivities of the composites increased with increasing GNP content as well as with increasing GNP particle size. The composites were found to be effectively electrically insulating, and it was found that the addition of GNP did ...
Biobased foams derived from lignins and tanins were produced by mechanical frothing and curing. The obtained foams did not crack after drying. The foams were found to be good thermal insulators with thermal conductivities ranging from 0.035 to 0.055 Wm-1K-1....
Using a three-roll mill process, graphite nanoplatelets (GNPs) were dispersed in a silicone polymer for application as a thermal interface material. Through the use of electron microscopy and XRD, the researchers were able to determine that the GNPs dispersed better when using the three-roll milling process as compared to previously used methods. GNPs were mixed with the silicone polymer in wt.% up to 25, with the highest wt.% yielding the highest ...
