ABSTRACT Understanding the rheological behavior of plasticized polylactide (PLA) contributed to optimization processing conditions and revealed microstructure–property relationships. In this study, morphological, thermal, steady dynamic properties PLA/poly(ethylene glycol) (PEG) blends were investigated by scanning electron microscope, differential calorimeter, capillary rheometers, respectively. The results illuminated that melt shear flow basically fitted power law, whereas temperature...
This study focused on achieving biodegradable thermoplastic polyurethane (TPU) blends with good mechanical properties by the incorporation of starch.
Abstract Producing high‐quality graphene and polymer/graphene nanocomposite is facing the problems of complex procedure, low efficiency, serious resource waste. To explore a new fabrication approach with high efficiency cost crucial for solving these technical issues, which becomes current research hotspot also great challenge. Herein, one‐step melt mixing strategy based on synergy steam explosion alternating convergent‐divergent flow, innovatively developed to fabricate high‐density...
In-situ fibrillation and intercalation structure are favoring to improve the properties of polymer blends. In this work poly(butylene succinate)/poly(lactic acid) blends containing such structures have been achieved via volume pulsating elongation flow instead strong shear. The mechanical properties, crystallization micromorphology extruders were well investigated. results showed that PBS PLA partially miscible compatibility improved mandatorily by flow. Evenly distributed oriented in-situ...

Abstract Expanded graphite (EG) is introduced into poly(vinylidene fluoride) (PVDF) by melt mixing extrusion with water injection. The results demonstrate that the unfunctionalized EG in composite prepared injection exbibits better dispersion than one without due to promoting role of during extrusion. Thus, PVDF/EG loading 4 wt% water‐assisted (WAME) exhibits electrical conductivity about three orders magnitude higher neat PVDF and order Comparing PVDF, thermal composites increased 101.5%...
Abstract The melt strength behavior and drawability during elongation flow of low density polyethylene (LDPE)/linear (LLDPE) blends were investigated using the Rheotens test method under temperature ranging from 160 to 200 °C die extrusion velocity varying 9 36 mm/s. It was found that blend decreased with a rise while increased increasing LDPE weight fraction when extension rate or drawing ratio is constant; dependence on roughly obeyed Arrhenius equation; index equation. at fracture...
Abstract The phenomenon of liquid sloshing inside partially filled tank trucks adversely affects the stability trucks. In order to mitigate negative effects tank, this study proposes several baffle configurations and investigates their anti-slosh effect on sloshing. First, a numerical model is established. Then, effectiveness validated by comparing results free surface deformation, wall pressure, frequency obtained from simulations experiments under identical conditions. During research...
Abstract Fiberglass‐reinforced composites are extensively utilized in a diverse range of fields. Nonetheless, relying on the high shear forces generated during twin screw extruder processing to enhance dispersion and distribution glass fibers (GFs) can result GF breakage degradation molecular chains polyamide (PA). Consequently, this leads diminished performance composite material. In study, high‐performance PA6/GF were effectively fabricated through utilization dual‐speed non‐twin operating...
Poly(lactic acid)/acetylated starch (PLA/AS) blends was prepared using a twin-screw extruder and two different types of single-screw extruder, respectively.
