“…The similarity of particle size between the biocarbon and talc was a key component in obtaining similar results, though more research is necessary to explain and explore which mechanisms if any, can explain the good compatibility between filler and PPA. Further studies were also conducted, by analyzing the result of blending PPA with PA410, 91 and optimizing the properties of the material space. 92 The studies presented here are only a sample of the possible applications and answer the question of why plastics have become one of the go-to materials to replace metal parts in vehicles.…”

The focus of this review is on the family of polymers commonly known as polyphthalamide (PPA), employed in the automotive industry along with other industries. This includes electrical parts, manufacturing or oil extraction because of PPAs chemical resistance, high strength, stiffness at high temperature, and dimensional stability. A significant amount of research was found and was divided into two main sections: first, PPA and its blends, and second, PPA composites. A consistent notation was devised to aid the understanding of older sources and enhance the comparison between different materials, increasing comprehension. Undiscovered or unpublished properties of PPAs means that there is a rich vein of opportunity, and many studies yet to be performed. This will open up a plethora of breakthrough research in electrical vehicle and aerospace applications.

“…14 The melting temperature of the copolyamides is reduced appropriately to improve their crystallization performance and processing characteristics. 15 To modify nylon 10T, many researchers have studied it in great depth. By using direct melt polymerization to create nylon 10T and nylon 10T/1010 samples, Wang et al investigated the impact of sebacic acid comonomer addition on the crystal shape and crystallization rate of the nylon 10T.…”

This work synthesized the pure poly (decamethylene terephthalamide) acid (PA10T) and a series of PA10T/10I through an efficient one‐pot melt polymerization method. The structures, thermal behavior, crystallization performance, and mechanical properties of PA10T and PA10T/10I were investigated by FT‐IR, DSC, TGA, POM, XRD, and mechanics performance testing, respectively. The thermal analysis demonstrates that the melting temperature of PA10T/10I gradually decreased with the increase of isophthalic acid (IPA) copolymerization proportions. Specifically, it was observed that, the Tm1 of pure PA10T was 299.5°C, while the Tm1 of PA10T/10I‐4 with a linear downward trend was 284.7°C. And the introduction of IPA copolymerization has an obvious beneficial effect on the thermal stability of PA10T/10I (Td,5 varied from 429.5 to 434.5°C) with a wider temperature range of processing, which could potentially be applied in high‐temperature scenes. POM and XRD were used to characterize the crystallization behavior of all samples further. It was discovered that although adding IPA did not alter the crystal structure of PA10T, it dramatically reduced the size of crystalline grains and increased the number of crystal nuclei. In addition, the copolyamides possess excellent mechanical properties, and the tensile strength of PA10T/10I varied between 42.91 and 46.89 MPa, the bending strength varied between 76.69 and 85.83 MPa, and the izod impact strength varied between 25.41 and 29.82 kJ m−2. Moreover, the influence of the IPA comonomer of copolyamides PA10T/10I on melting points, thermal stability, crystallization behavior, and mechanical characteristics was investigated. This work provides a reference for preparing biobased semi‐aromatic copolyamides PA10T/10I with outstanding processing performance, excellent thermal characteristics, and adjustable mechanical properties.

“…Blending is a convenient, effective, and low-cost method for improving the processability of polymeric materials and enhancing their properties [ 7 ]. Several PA blends have been reported, such as those with polypropylene [ 8 ], polyethylene [ 9 ], polyethylene terephthalate [ 10 ], polylactic acid [ 11 ], acrylonitrile butadiene styrene [ 12 ], and two types of PA [ 13 , 14 , 15 ].…”

Crystallization and Performance of Polyamide Blends Comprising Polyamide 4, Polyamide 6, and Their Copolymers

Polyamide 4 (PA4) is a biobased and biodegradable polyamide. The high hydrogen bond density of PA4 bestows it with a high melting point that is close to its thermal decomposition temperature, thereby limiting the melt processing of PA4. In this study, PA4 was blended with polyamide 6 (PA6) and further modified with copolyamide 4/6 (R46). The effects of composition on the crystallization behavior of the blends were studied. The results demonstrated that the binary PA4/PA6 (B46) and ternary PA4/PA6/R46 (B46/R46) blends formed two crystalline phases (PA4- and PA6-rich phases) through crystallization-induced phase separation. With increasing PA6 content, the thermal stability and crystallinity of the B46 blend increased and decreased, respectively, and the contribution of PA6 toward the crystallization of the PA4-rich phase diminished. Molecular dynamics simulations showed the molecular chain orientation of the B46 blends well. The melting points, crystallinities, and grain sizes of the B46/R46 blends were lower than those of the B46 blends. The crystallization of the PA4-rich phase was restrained by the dilution effect of molten-state PA6, and the nucleation and crystallization of the PA6-rich phase were promoted by the presence of crystallized PA4. The B46 blends with 30–40 wt% PA6 had the best mechanical properties.
