Thermal decomposition studies of bio-resourced polyamides by thermogravimetry and evolved gas analysis

Ignition Activation Energy of Materials based on Polyamide 6

“…Under oxidative atmosphere, the major products of degradation were carbon monoxide, carbon dioxide, water and ammonia. (Pagacz et al, 2015) Similar results were also mentioned by Herrera et al (2001) According to their results the polyamides decompose apparently in one step in nitrogen and in two steps in air, but a detailed study confi rmed that the decomposition has two steps in nitrogen and at least three steps in air. The extra step in air is due to the degradation of the char formed in the fi rst step.…”

A Novel 2D Porous Print Fabric-like α-Fe2O3 Sheet with High Performance as the Anode Material for Lithium-ion Battery

“…9a), the peak intensity of the flower spikes after ammonia treatment has a distinct decrease at 1742 cm -1 (Fig. 9b) assigned to the characteristic peak of esters carbonyl [42]. [45,46], we deduce the alkali ammonia solution here may be also used as the porogen.…”

Effect of food chemicals and temperature on mechanical reliability of bio-based glass fibers reinforced polyamide

“…The demand for advanced Polyamides (PA) in different industry fields as automotive and transportation, electrical and electronic goods, household and professional appliances, is expected to witness significant growth in the next ten years [1,2]. Among the several grades of commercial available PAs, bio-based ones are fully or partially synthesized from renewable resources, as castor and palm kernel oil, biomass and biobased acid [3][4][5][6]. In industrial applications, these polymers recently gained increasing interests due to their good mechanical (hardness, high toughness, and abrasion resistance), thermal (high melting point and glass transition temperature), [3] and eco-properties.…”
