Improved thermal properties of borosilicate glass composite containing single walled carbon nanotube bundles

A single walled carbon nanotube (SWCNT) incorporated borosilicate glass composite was fabricated by a melt quench technique. The thermal diffusivity, specific heat and the thermal conductivity of the base glass and the composite were determined together with their temperature profile. Enhancement of the diffusivity and the conductivity in the composite was found compared to that of the base glass. The interfacial thermal resistance (R-k) plays a decisive role in the thermal transport properties of the composite. Furthermore, the effect of phonons was discussed to substantiate the transport mechanism and the temperature profile of different thermal parameters.
