Abstract:
ABSTRACT In this study unsaturated polyester resin (UPE) mixed with different weight percent 2, 4, and 6% of toner carbon nano powder (TCNP) were used to prepare polyester composite . The molding method was used to prepare UPE and UPE/TCNP composites specimens. Study of non isothermal decomposition kinetics of UPE and UPE/TCNP composites were carried out by utilizing thermo gravimetric analysis (TGA). The samples were heated from ambient temperature to 800 °C at different heating rates 5, 10, 15, and 20 Co/min under helium as inert gas was used with flow rate 20 ml/min to yield gases and solid char. TG and DTG curves obtained from the decomposition were analyzed using iso-conversional method of Flynn and Ozawa, Coast-Redfern, and Horowitz-Metzgers methods. Kinetic parameters were determined for all specimens were satisfactory presenting good correlation with linear correlation coefficient close to unit using SPSS package and was in a good agreement with published data. The experimental results show the decomposition of UPE/TCNP composites obtained from thermal gravimetric analysis is faster comparing with those UPE specimens. This enhancement is attributed to iron content in TCNP. The aim of this work is to characterize the thermal decomposition process in the relation to its kinetics, and thermodynamics property.
