Influence of U.V light on the thermal properties of HDPE/Carbon black composites

摘要

Solar Energy is one of the most abundant renewable sources of energy and free on planet earth.For water mounted solar photovoltaic systems, HDPE material is found to be best suited for themanufacturing of floating bed structure. The major limitation in this regard is the effect of UVradiations present in the natural environment that leads to the degradation of plastic materials. Inthe present study, the carbon black is used as a UV resistant additive which is mixed with the baseHDPE material under different concentration starting from 1% to 3%. The thermal behavior of theHDPE/Carbon black composite floats so formed are observed before and after U.V exposure. FTIRand DSC curve confirms that carbon black is dispersed uniformly in the HDPE matrix and there isno degradation in the polymer after exposure to U.V light.
