Poly(ethylene terephthalate)/polyethylene composite based on in-situ microfiber formation

Morphological and mechanical properties of biodegradable poly(glycolic acid)/poly(butylene adipate-co-terephthalate) blends with in situ compatibilization

“…This phenomenon was similar to the concept of in situ microbrillar-reinforced composites (iMFCs), the microbrillar structure of the reinforcing polymer within the polymer matrix was formed during processing. 33,34 But for traditional iMFCs, extra stretching was necessary, and the component with higher melting temperatures (T m ) usually formed microber. [35][36][37] For our system, the formation of in situ microbrillar structure just during injection molding and the microber formed in PBAT with relative low T m is unexpected.…”

Influence of Strong Shear Field on Structure and Performance of HDPE/PA6 In Situ Microfibril Composites

“…But during the process of manufacturing these composites, the fibers may break as a result of shearing and agitation by the processing equipment, which reduces the length-to-diameter (L/D) ratio of the fibers and even leads to a decrease in the mechanical properties of the material [16]. Fortunately, the in situ microfibril composite (MFC) has stood out from the traditional polymer composites and attracted the attention of many researchers due to its great potential in mechanical enhancement and huge advantage in manufacturing over the past few decades [17,18]. Compared with common inorganic fiber polymer composites, the fibers of MFCs are formed during processing, which prevents fibers breaking Polymers 2024, 16, 1032 2 of 13 caused by screw agitation.…”

Insight into Understanding the Influence of Blending Ratio on the Structure and Properties of High-Density Polyethylene/Polystyrene Microfibril Composites Prepared by Vibration Injection Molding

“…With the development of the polymer composite industry, fiber composites have been investigated for decades and are used in many areas of our daily life, such as high-strength composites, absorption materials, biodegradable materials, etc. Among different kinds of fiber-reinforced composites, one type named “microfibril reinforced composite (MFC)” has evoked researchers’ interest for its huge advantage in manufacture and great potential for functionalizing and strengthening. − Though MFC exhibits great advantages, there still exists one problem: the fibril is formed during drawing, so a remelting step is necessary. Lately, researchers found that these special composites can be prepared under some designated process technologies, such as microinjection molding and gas-assisted injection molding, , which can provide strong shear force during process.…”
