Graphene Nanoplates

A hybrid heat-conducting filler based on graphene nanoplates and multi-walled nanotubes was obtained to increase the thermal conductivity of an epoxy binder, exhibiting a synergistic effect. This effect is achieved due to the embedding of multi-walled nanotubes between graphene nanoplates and the formation of effective percolation networks in the composite. The dependence of an increase in the thermal conductivity of an epoxy composite on the mass ratio of graphene nanoplates and multi-walled nanotubes in a mixture of a hybrid filler has been established. The effect of the hybrid filler concentration in the epoxy matrix and the mixing method of graphene nanoplates and multi-walled nanotubes on the thermal conductivity of the composite was found. A synergistic effect between graphene nanoplates and multi-walled nanotubes has been demonstrated, leading to a sixfold increase in the thermal conductivity of epoxy composites at a filler concentration of 5 wt%.

Hybrid Fillers

Thermal conductivity of polyetheretherketone (PEEK) with fillers was investigated. By adding the hybrid fillers to polymer the thermal conductivity of composites was increased significantly. Thermal diffusivity of composites was measured using laser flash method. Synergistic filler effect between particulate SiC and carbon fiber (CF) was observed for thermal conductivity. In a PEEK based composite, thermal conductivity increased to 8.25 W/m-K for a 50 vol% hybrid filler (SiC+CF) system, whereas the thermal conductivity of 40 vol% CF was 3.1 W/m-K and 50 vol% of SiC was 2.4 W/m-K, respectively. The use of hybrid filler was found to be effective in increasing thermal conductivity of its composites due to formation of effective thermal conductive path. Experimental results of two-phase system were compared with Nielsen prediction.

Silica aerogel/epoxy composite, a kind of efficient thermal insulation material, was prepared by doping silica aerogel of different sizes into epoxy resin through thermocuring process. The results of thermal experiments showed that silica aerogel/epoxy composite had a lower thermal conductivity (0.105W/(m·k) at 60 wt% silica aerogel) and higher serviceability temperature (Martens heat distortion temperature: 160°C at 20 wt% silica aerogel). In addition, the composite doping larger size (0.2-2mm) of silica aerogel particle had lower thermal conductivity and higher Martens heat distortion temperature. Based on the results of SEM and FT-IR, the thermal transfer model was established. Thermal transfer mechanism and the reasons of higher Martens heat distortion temperature have been discussed respectively.

Good Agreement

In this study, the transport theorem of phonons and electrons is utilized to create a model to predict the thermal conductivity of composite materials. By observing or assuming the dopant displacement in the matrix, a physical model between dopant and matrix can be built, and the composite material can be divided into several regions. In each region, the phonon or electron scattering caused by boundaries, impurities, or U-processes was taken into account to calculate the thermal conductivity. The model is then used to predict the composite thermal conductivity for several composite materials. It shows a pretty good agreement with previous studies in literatures. Based on the model, some discussions about dopant size and volume fraction are also made.
