Abstract : This paper is aimed at evaluating the effect of MWCNTs (Multi Walled Carbon Nanotubes) on the thermal conductivity of PP (Polypropylene) based polymer composite material. Since MWCNTs possess extremely high thermal conductivity of nearly 3500W/mK, it is expected to increase the thermal conductivity of any matrix material to which it is added in minor quantities. We fabricated composite specimen of PP/MWCNTs with different compositions of MWCNTs (5wt% and 10wt %) and compared their coefficients of thermal conductivities with that of pure PP specimen using a digital PID temperature controller. It was observed that, with increase in composition of MWCNTs in PP, there is rapid heat transfer across the surfaces of the specimen which are exposed to different temperature conditions. Heat conduction was assumed to follow Fourier’s Law of thermal conductivity which indicated that the relative thermal conductivity for 5wt% PP/MWCNT specimen was higher by nearly 3% to 5% in comparison to pure PP specimen while relative thermal conductivity of 10wt% PP/MWCNT specimen was higher by nearly 4% to 10% within a temperature difference range of 700C to 450C when steady state is reached. These results are significant from the aspect of applications where quick heat dissipation is required. Under extreme temperature conditions, where armed forces are required to wear heavy clothing such as caps, jackets, gloves etc., these types of polymer composite materials can be used in such a way that they can transfer heat into a specific region from the atmosphere and away from the body.
