Analysis of Thermal Performance of Polylactic Acid Nanocomposite by Using T-History Method

Abstract

In this study, we perceived the thermo-physical boundary and the thermal efficiency of zinc oxide for volume fraction in polylactic acid based on a heat energy storage system was examined by using the T-history method. The use of the T-history method for the assessment of thermo-physical boundary describes the specific heat capacity and thermal conductivity enhanced in solid as well as liquid phases of the mixture until the addition of 0 to 0.025% of volume part of zinc oxide in the polylactic acid nanocomposite. After the addition of the zinc oxide, the heat of fusion falls and polylactic acid has a high rate of fusion related to 0.025% volume part of zinc oxide mixed with polylactic acid. Further zinc oxide-based polylactic acid nanocomposite has 31.30% and 13.5% higher solid as well as liquid thermal conductivity in comparison with polylactic acid. Moreover, raise the particle size and analysis as well as distributions found by dynamic light dispersing method for different volume parts of zinc oxide mixed on polylactic acid. In contrast to the thermal efficiency analysis of 0.025% of volume fraction zinc oxide in polylactic acid nanocomposite has a 30.6% high heat transfer rate related to pure polylactic acid along the stage of 4 minutes. Further, the addition of zinc oxide above 0.025% volume fraction in polylactic acid, rise the particle settlement rate freely. Whatever can become to end that 0.025% volume fraction of zinc oxide in polylactic acid mixed thermal energy storage arrangement outcome of maximum thermo physical property and thermal efficiency.
