“…Furthermore, the resin can be processed using various methods, including injection molding, extrusion, blow molding, coating, spinning, and modification, to produce a range of industrial and civilian plastic products. Its broad application in industries, such as electronics, automobiles, building materials, medicine, and packaging, makes it a popular choice. − PP is a nonpolar polymer that is susceptible to the effects of ultraviolet (UV) radiation, which can result in the formation of alkyl radicals in the molecular chain. Additionally, exposure to oxygen leads to the creation of new radicals that react with other hydrogen atoms in the chain, causing PP to lose its original properties.…”

The anti-aging agent TiO2–polyacrylonitrile (PAN) and the mechanical strengthening agent CSW–PAN were prepared by radical polymerization using rutile nano-titanium dioxide (TiO2) and anhydrous calcium sulfate whisker (CSW) as raw materials. The structures of TiO2–PAN and CSW–PAN were characterized using Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS). Simultaneously, the mechanical properties, aging properties, and thermal stability of TiO2–PAN/CSW–PAN/polypropylene (PP) composites were studied, and the results showed that the surfaces of nano-titanium dioxide and calcium sulfate whiskers were successfully grafted with acrylonitrile. Owing to the introduction of new elements, such as acrylonitrile, nano-titanium dioxide and calcium sulfate whiskers have anti-aging properties. In comparison of the impact strength and tensile strength of TiO2–PAN/PP and TiO2–PAN/CSW–PAN/PP before aging, it can be proven that adding CSW–PAN can significantly enhance the mechanical properties of TiO2–PAN/CSW–PAN/PP. After 1000 h of aging, the tensile strength of the ternary composite TiO2–PAN/CSW–PAN/PP was 19.88 MPa when the addition amount of TiO2–PAN and CSW–PAN was 3%. Moreover, the impact strength of the ternary composite material TiO2–PAN/CSW–PAN/PP after 1000 h of aging is even better than that of non-aging pure PP materials, proving that the service life of improved PP products is extended, unnecessary waste and environmental pollution can be relieved, and the needs of specific engineering fields can be met.

A novel thermoplastic elastomer, kernel resin (KN), α‐nucleating agent (HPN), and β‐nucleating agent (DCHT), which acted as toughener and nucleating agents (NAs), were used to improve the mechanical properties and crystallization behaviors of isotactic polypropylene (PP). The impact strength of the PP/KN blends increased significantly with increase in KN concentration. Surprisingly, the impact strength of PP/KN/NA blends improved further upon addition of NA. The toughening effect of DCHT was stronger than that of HPN. The maximum impact strength of PP/KN/DCHT blend reached 69.2 kJ/m2 when the DCHT content was 0.05%, which was six times higher than that of neat PP. The SEM images of fractured surfaces of the blends showed a change from brittle fracture to ductile fracture. Moreover, the WAXD results showed that the incorporation of HPN promoted the formation of the α form of crystalline PP. Addition of DCHT induced the generation of α‐β crystal transition of PP. Furthermore, differential scanning calorimetry showed that the crystallizability and the overall crystallization rate of PP were enhanced by the addition of KN and NA. The half‐crystallization time of PP at 128°C decreased from 5.52 (neat PP) to 0.34 min (PP/KN/DCHT‐0.3).

In this study, a comparative analysis of the use of recycled PET (R‐PET) in synthetic and natural fiber blended composites was made. PET, R‐PET, and PP yarns were folded with reinforcing fibers by commingling technique and then fabrics were prepared using weaving technology. Hot compression molding technology was used for composite fabrication. Tensile and impact characterization revealed the significant influence of reinforcing and TP fibers on mechanical properties. R‐PET matrix glass fiber reinforced composites exhibited 41.77% higher tensile strength than virgin PET and 20.41% higher than PP. In terms of tensile strength for linen reinforced samples, R‐PET shows an impressive 181% improvement over virgin PET and 154% over PP. According to the drop weight test results, glass fiber reinforced R‐PET matrix sample exhibited a peak load value 53% higher than that of the virgin PET matrix, although it was 9.47% lower than the PP matrix. In linen fiber reinforced samples, R‐PET demonstrated a 57.73% improvement over virgin PET but lower by 9.47% compared to the PP matrix. During this time, DSC, TGA, FTIR, and flammability tests were also performed on the composite samples. The results showed that R‐PET has easy processability as a matrix material and provides better wetting of the reinforcing fibers. For this reason, it has been shown that R‐PET matrix samples provide better mechanical properties than both PET and PP matrix samples. It has also been determined that R‐PET is a more suitable matrix material compared with natural fiber reinforced composites.Highlights Commingled yarns were used for preparing composites. R‐PET yarns were used as matrix in preparing glass and linen reinforced composites. R‐PET was compared with virgin PET and PP yarns. R‐PET showed great potential in easy preparation of TP composites. Composites made with R‐PET showed improved thermal and mechanical properties.
