Thermal Stability of Cotton Cellulose Modified with Calcium Complexes

Article Preview

Abstract:

Complexes of cell-THPC-thiourea-ADP with Ca2+ have been prepared. The thermal stability and smoke suspension of the samples are determined by TG, DTA and cone calorimetry. The activation energies for the second stage of thermal degradation have been obtained by following Broido equation. Experimental data show that for the complexes of cell-THPC-thiourea-ADP with Ca2+, the activation energies and thermal decomposition temperatures are higher than those of cell-THPC-thiourea-ADP, which shows these metal ions can increase the thermal stability of cell-THPC-thiourea-ADP
