TG-DTA, TEM, and IR were used to investigate the thermal decomposition behavior of poly( N -vinyl-2-pyrrolidone) (PVP). The TG-DTA results show that the thermal decomposition behavior of PVP on platinum (Pt) is quite different from that of pure PVP. For pure PVP, 95.25% is decomposed...

According to the TG curves of both HA powders, the major difference of the mass loss appearedat the tem- perature up to 500 ◦ C. The mass losses of HA-PVP and HA-CTAB are 6.89% and 3.42%, respectively. The as-synthesized raw HA-PVP powders have a morphology of irregular nanorods...

The thermal behavior and phase changes within the fibers were investigated by DSC and TGA/DTA. Five precursors with different PVP loading in ethanol were electrospun. The mats shrinkage as function of temperature was measured in the RT–200°C range. Shrinkage rate drastically increased above the ...
