Simultaneously achieving super toughness and reinforcement of immiscible high-density polyethylene/poly(ethylene terephthalate) composite via oriented spherical crystal structure

Lightweight and High Mechanical Properties of In Situ Poly(ethylene terephthalate) Reinforced Polypropylene Composite Foams by Chemical Foam Injection Molding

“…As the same results in yield strength, both INF composite exhibited much bigger impact strength, being enhanced by 47 and 68%, respectively. The improved toughness was due to the synergistic effect of PET nanofibrils and Talc fillers, thus being able to promote the shear plastic deformation of the polymer chain and to inhibit the crack initiation and propagation . After the CFIM process, the impact strength of neat PP slightly decreased.…”

“…The improved toughness was due to the synergistic effect of PET nanofibrils and Talc fillers, thus being able to promote the shear plastic deformation of the polymer chain and to inhibit the crack initiation and propagation. 53 After the CFIM process, the impact strength of neat PP slightly decreased. This happened because the large size, as well as the nonuniform cellular structure, accelerated crack initiation and propagation under impact loading.…”

Development of sustainable cellulose‐based composite of polypropylene reinforced by recycled microfibrillar poly (ethylene terephthalate)

“…Among the petroleum-based polymers, polyethylene terephthalate (PET) receives great attention and interest in recent years, since it can be relatively easy recycled. [39][40][41][42][43][44] Melt compounding of recycled polyethylene terephthalate (RPET) with various polymers have been explored to overcome loss of mechanical properties and molecular weight of recycled PET, including polyethylene, 45 polypropylene, 46 and so forth. Polypropylene (PP) has been widely used in this case due to its low density, good surface hardness, good abrasion resistance, and excellent electrical properties.…”

“…PP grafted with maleic anhydride (also known as maleated PP) has been extensively used as a compatibilizer in PP/PET blends to improve dispersion, interfacial adhesion, and mechanical properties of blend. 45,47 Recently, greater attention is being paid to the employment of renewable resources as reinforcement in polymeric blends and composites as a result of the growing interest and stricter environmental regulations in the appropriate use of natural resources. Accordingly, incorporation of WF to polymer blends as reinforcing filler has been reported.…”

“…However, due to the notable difference in melting temperatures and immiscibility of these two polymers, compatibilizers, and coupling agents should be employed. PP grafted with maleic anhydride (also known as maleated PP) has been extensively used as a compatibilizer in PP/PET blends to improve dispersion, interfacial adhesion, and mechanical properties of blend 45,47 …”
