Abstract Glass fiber‐polyamide 6 (PA6) composites are widely used for various automotive applications, yet the ability to exhibit multifunctional properties and cost of it remains challenging. Herein this work introduces a cost‐effective approach utilization waste glass fiber (GF), green aluminium metal organic framework (Al‐MOF), industry‐grade graphene nanoplatelets (GNPs) fabrication PA6 thermoplastic with enhanced mechanical performance fire retardancy. The results demonstrate that...

Abstract Basalt fiber reinforced polypropylene composites with two initial lengths (3.2 and 6.4 mm) were fabricated using twin‐screw extrusion compounding. In the case of smaller length, basalt fibers predominantly served as nucleating agents for thereby resulting in an increase degree crystallinity. The addition polypropylene‐g‐maleic anhydride (PP‐g‐MA) caused matrix to become amorphous, which was due establishment a fiber–matrix interphase. This behavior different relatively larger length...

Metal–organic framework (MOF) nanostructures provide unique opportunities in the fabrication of multifunctional polymer nanocomposites. However, achieving both enhanced mechanical properties and fire safety using labile metal–organic reinforced epoxy composites is usually challenging, calling for post-synthetic modification (PSM) MOFs. In this study, we have synthesized an organophosphorus functionalized zirconium-based MOF, P-UiO-66 NH2 (P-MOF). This as-synthesized modified MOF when with...

The wide applicability of proton exchange membrane fuel cells (PEMFCs) is hindered by their dependency on the Nafion as a state-of-the-art electrolyte. membranes can only operate at relatively low temperatures, up to 80°C. Therefore, any application cell above this temperature would cause PEMFC lose its conductivity and mechanical integrity. For reason, development Nafion-free for PEMFCs has been studied extensively through corporation several additives over polymer substrates. charge...
