“…Toshi Hira et al 13 investigated the effect of carbon nanotubes on the polyamide six matrix. With the addition of carbon nanotubes, the tensile modulus increased by 6% and the tensile strength by 10% which shows the proper interfacial interaction between CNT and polyamide six chains.…”

In this research, the mechanical properties of polyamide 6/polyolefin elastomer (PA6/POE) blends reinforced with carbon nanotubes have been studied. Nanocomposites consisted of 10 and 20 wt% polyolefin elastomer, 0, 1, 2, and 3 wt% carbon nanotubes (MWCNT) and 5 and 10 wt% maleic anhydride (POE-gMA as coupling agent) were made by an internal mixer based on the full factorial design of experiment. Tensile and impact tests were performed to extract mechanical properties including tensile strength, elastic modulus, and impact strength. Scanning electron microscope (SEM) was used to observe the dispersion and distribution quality of MWCNT in the matrix. SEM images showed an acceptable distribution of carbon nanotubes up to 2 wt% in both polyamide matrices with 10 and 20 wt%, while adding 3 wt% of nanotubes in both matrices was associated with nanotubes accumulation. The test results showed that the addition of 2 wt% of carbon nanotubes improved the tensile strength and elastic modulus of the compounds by 21% and 23%, respectively. Also, the presence of up to 20 wt% of polyolefin and 10 wt% of the compatibilizer has increased the impact strength of the compounds. Finally, the R-squared above 92% for all mechanical properties showed that there is a good agreement between the experimental results and the extracted regression models.

The preparation process from waste fibers to regenerated fibers is an environmental significance work. In this work, liquid chromatography/time‐of‐flight mass spectrometry, advanced polymer chromatography/multi‐angle laser‐light‐scattering/refractive index detector, and two‐dimensional wide‐angle X‐ray diffractometry were employed to characterize the polycaprolactam(PA6) fibers above oligomers composition and content, molecular weight and distribution, crystallization and orientation, and analyzing the changes in mechanical properties. The total content of oligomers in physical and chemical regenerated PA6 fiber is 2.084 wt% and 1.812 wt%, individually, which is higher than that in waste PA6 fiber. And the oligomer content of C1–C4 (cyclic monomer, cyclic dimer, cyclic trimer, and cyclic tetramer) in the regenerated PA6 fiber is higher than that of waste PA6 fiber. The regenerated PA6 fiber sample contains more low‐molecular‐weight substances, making it easier to form crystal nuclei and crystallize. During the dyeing process of the regenerated PA6 fiber, the γ crystal transformed into α crystal. The tensile strength of physical and chemical regenerated PA6 fiber is lower than that of waste PA6 fiber. And after dyeing, the oligomers content of regenerated PA6 fiber is significantly decreased, especially in C1–C4 oligomer. However, the crystalliniy and orientation of regenerated PA6 fibers were improved, which also leads to the fracture strength increased by about 20% compared to undyed fibers.
