The effect of marine sediments on the mechanical properties and thermal stability of proteinic biopolymer

Abstract

This article focuses on the valorization of marine sediments (MS) in proteinic biopolymer (HE) that will generate HEMS biocomposites. These biocomposites were developed with various percentages of marine sediments (0%, 5%, 15%, and 20%) and characterized. Mechanical properties were examined as a function of the contents of used marine sediments. The flexural and compressive modulus increase with the rise of the MS percentage in the composite. The compressive strength increases while the flexural and tensile strengths decrease. Furthermore, the HEMS composite was characterized using Fourier transform infrared spectroscopy and by using scanning electron microscopy. And the thermal degradation behavior of the composite was investigated by thermogravimetric analysis coupled with differential scanning calorimetry. POLYM. COMPOS., 38:1624-1630

Development of high‐performance biopolymer nanocomposites derived from carboxymethyl chitosan/boehmite via green synthesis

“…The increased thermal stability caused by the addition of boehmite can be attributed to the strong interaction between the CMCS and the boehmite nanofiller, which in turn resists the nanocomposites from decomposition. [ 23,25 ] Moreover, the examination of char residue left at 600°C for each sample further confirms the thermal stability. The residual weight of pure CMCS ⁓ 28% whereas 3, 7, and 10 wt% loaded films gradually increased to ⁓ 32%, ⁓34%, and ⁓ 36%, respectively.…”
