Thermal degradation of biodegradable blends of polyethylene with cellulose and ethylcellulose

Biocomposites of Bio-Polyethylene Reinforced with a Hydrothermal-Alkaline Sugarcane Bagasse Pulp and Coupled with a Bio-Based Compatibilizer

“…The BioPE filament degraded in a single step that started at 464.4 • C as shown in Figure 5a; this process takes place rapidly and the quantity of residue is very small (0.26%). However, the BioPE composites showed two-step decomposition, where the first starts at 332-356 • C (onset temperature range), corresponding to the cellulose decomposition (around 330 • C) [34]. The second step begins at a similar onset temperature (468-469 • C), involving a fast and significant degradation attributed to the thermal cracking of the hydrocarbon chains of BioPE, which ends approximately around 510 • C [35].…”

Mechanical, thermal and morphological characterization of cellulose fiber-reinforced phenolic foams

“…The third step takes place at temperatures higher than 500 C and was attributed to the formation and release of carbonaceous substances [19,20]. The cellulose fibers mainly degraded in one step (250e400 C) in which the cellulose decomposes through the formation and decomposition of levoglucosan [21,22]. At temperatures higher than 400 C polynuclear aromatic structures and carbonaceous char are formed [22].…”

Thermal decomposition kinetics of sodium carboxymethyl cellulose: Model-free methods

“…A broad range of the activation energy of SMC could be attributed to the linkage scissions in the functional groups followed by the scissions of linkage on the chain. These processes occurred via radical chain mechanism by decreasing of the barrier energy for the decomposition process [34,35]. In general, the dependence of E on the fraction of mass conversion is associated with the occurrence of parallel, consecutive, and irreversible reactions on the thermal degradation process of the polymers [36].…”
