Resin polymers, such as Polymethyl methacrylate (PMMA), have been used in denture fabrication because of their easy molding ability and flawless appearance. However, these PMMAs are not the most desirable material when dealing with mechanical strength, electrical conductivity and thermal stability. In this study, the addition of fillers, such as Nano-Aluminum Oxide (Nano-Al2O3) and plasma treated polypropylene (PP) fibers, to these polymers has been explored. Nanocomposites are desired in ...
Low-temperature expandable graphite (LTEG) was blended into low-density polyethylene (LDPE) to prepare composite materials with an enhanced thermal conductivity in comparison to pure LDPE. The thermal conductivity of a composite containing 60 wt. % LTEG was found to be increased by a factor of 23 in comparison to the pure polymer. The LTEG was also found to decrease the melting temperature and degree of crystallinity of the LDPE, and the composites were also ...
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. ...
The effects of the addition of three different fillers to a polymer matrix on the thermo-physical properties of the resulting composites were investigated by the authors. Boron nitride, synthetic diamond, and silicon nitride were used as the fillers (up to 2 vol. %), and it was found that their addition did increase the thermal conductivity relative to that of the pure epoxy matrix. Furthermore, it was determined that the thermal conductivities of ...
This article is a review of the methods for measuring thermal conductivity including both steady state and transient methods. The article describes the experimental setup for each method, and it gives a brief description of the theory of each method. A review of models that have been developed for the prediction of thermal conductivity of polymeric nanocomposites is also presented....
