Thermogravimetric analyses filler surface

Zhou et al. [173] studied the effects of surface treatment of calcium carbonate particles with sulfonated polyether ether ketone on the mechanical and thermal properties of composites with polyether ether ketone in various proportions prepared using a twin-screw extruder. These workers used tensile, impact, and flexural testing, thermogravimetric analysis, differential scanning calorimetry, and scanning electron microscopy. The influences of filler particle, loading, and surface treatment on deformation and crystallinity of polyether ether ketone were discussed. [Pg.82]

As has been mentioned, evaluation of the thermal performance of the surface-modified filler, as well as of composite materials, is important, because it affects the properties of the final nanocomposites significantly. High-resolution (Hi-Res) thermogravimetric analysis (TGA), in which the heating rate is coupled to the mass loss, that is, the sample temperature is not raised until the mass loss at a particular temperature is completed, is the method most commonly used for analysis of the thermal performance of materials.
