Polypropylene carbonate thermogravimetric analysis

The polypropylene continuous phase was transparent and epoxy phase appeared dark in the optical micrograph. However, the cause of elongated structure was not fully understood. The formation of elongated structure could be due to the friction between carbon black coated dispersed particles and the matrix (61), which decreased the interfacial tension between the immiscible polymers (63) or both (64). Based on extraction studies and thermogravimetric analysis, it was concluded that nearly all the carbon black particles were located in the epoxy matrix. [Pg.643]

Studies of thermal and fiie resistant properties of the polypropylene/multi-walled carbon nanotube composites (PP/MWCNT) prepared by means of melt intercalation are discussed. The sets of the data acquired with the aid of non-isothermal thermogravi-metric (TG) experiments have been treated by the model kinetic analysis. The thermal-oxidative degradation behavior of PP/MWCNT and stabilizing effect caused by addition of multi-walled carbon nanotube (MWCNT) has been investigated by means of thermogravimetric analysis (TGA) and election paramagnetic resonance (EPR) spectroscopy.

Xoller and co-workers [8], and Li and co-workers [9] used Py-GC-MS techniques and thermogravimetric analysis - infrared (TGA-IR) spectroscopy to study the thermal decomposition characteristics of polypropylene carbonate. [Pg.172]
