Exfoliated clay nanocomposites of renewable long-chain aliphatic polyamide through in-situ polymerization

The current study was performed to synthesize a series of renewable polyamide 614/organoclay nanocomposites (PAC) with the improved structural, mechanical, and thermal properties via in-situ polymerization. uniform dispersion exfoliation clay into PA614 matrix, particularly at lower loading organoclay (less than 3%), confirmed structural analyses (XRD, SEM, TEM). Furthermore, mechanical tests revealed remarkable improvement; namely, tensile strength storage modulus increased by 27% 30%, respectively, in sample contained 2% organoclay. Similarly, TGA results showed slight improvement stability nanocomposite samples. Altogether, these improvements excellent compatibility between nanofiller matrix homogenous PA achieved employing all samples illustrated shear-thinning behavior over frequency attributed lack time for polymer chain respond applied oscillation. Finally, crystallinity diminished upon increasing filler's content, which could be due decrease free volume resulting from presence To sum up, investigation supported benefit polymerization PA614/clay enhanced physio-mechanical properties, appropriate candidates engineering applications.
