Thermal decomposition analysis of Co2+ content alginic acid cross-linked structure for the synthesis of cobalt oxides

Development of Sustainable, Mechanically Strong, and Self-Healing Bio-Thermoplastic Elastomers Reinforced with Alginates

“…To understand the thermal behavior of A, a DSC thermogram of the pure powder was performed ( Figure 4 c), showing two distinct zones: On one hand, an endothermic reaction between 120 °C and 200 °C was associated with the dehydration processes of the material [ 27 , 28 ]. Since alginic acid has a chemical structure composed of plenty of carboxylic and hydroxyl groups ( Figure 1 b), its tendency to absorb water is considerable and can affect its thermal performance.…”

“…Figure S2 shows the thermogravimetric curve of A, while Figure 8 c,d show the weight change (%) and the first derivative as a function of the ZnO and A contents, respectively, of the prepared compounds. It was clearly observed that the composites present two important degradation episodes, which are associated with the presence of A (between ~200 °C and ~350 °C) [ 27 , 28 ], and the main degradation (around ~400 °C), associated with the matrix components. The incorporation of A affected the thermal stability of the compounds.…”
