| Abstract: | Polypropylene/multiwalled carbon nanotubes(PP/MWNTs) and polypropylene/organo-montmorillonites(PP/OMMT) composites were prepared via melting blending.Thermal gravimetric analysis was applied to record the thermal degradation behavior of the composites under nitrogen atmosphere with different heating rates.The thermal decomposition data were analyzed with Kissinger and Ozawa Methods.It showed that both MWNTs and OMMT could enhance the thermal resistance of PP matrix,and the apparent activation energy of PP/O... |
