Pyrolysis, kinetics and thermodynamic analyses of rice husks/clay fiber-reinforced polylactic acid composites using thermogravimetric analysis

Abstract In the context of processing, utilization and disposal polylactic acid composites, pyrolysis is a promising technique that addresses this complex synergy. work, kinetics thermodynamic parameters rice husks/clay fiber-reinforced PLA composites were investigated using Kissinger–Akahira–Sunose (KAS) Ozawa–Flynn–Wall (OFW) at multiple heating rates (16, 25 34 °C min −1 ). composites’ followed single-step degradation process. The flammability indices, combustion characteristic indices mean reactivities obtained for are much lower than those neat (2.00 × 10 −5 –2.44 % −2 , 0.87 −8 –1.79 −3 6.97 –8.04 respectively) which signals husks clay improved flame retardancy accruing composites. average activation energy values from KAS method found to be in ranges 137.83–143.99 kJ mol 124.51–133.95 raw modified respectively. Corresponding energies OFW 141.24–146.92 128.17–137.50 By comparing enthalpy, it was favored format activated due low barrier.
