Thermal Decomposition Kinetics of PLLA/Talc/TBC Composites

摘要：

　　To enhance the crystallizability and flexibility,Poly L-lactide (PLLA)/ Talc/tributyl citrate(TBC) composites were prepared via melt extrusion and investigated by thermogravimetry (TG) and derivative thermogravimetry (DTG).It was shown that the thermal decomposition temperature of PLLA/Talc (97∶3) and of PLLA/Talc/TbC (96∶3∶1) had increased 7.6 ℃ and 16.2 ℃ respetively compared with pure PLLA.The thermal decomposition kinetics of pure PLLA and composites were studied by using the Ozawa-Flynn-Wall (OFW) and the Friedman methods respectively,the results indicated that the apparent activation energies of PLLA/Talc/TBC composites increased sharply in the initial stage of the mass loss.
