Poly(ethylene terephthalate) PET, is a material of great commercial importance, in the form of fibers, bottle resin, and to a lesser extent, as a molding resin. In 1990, the annual world production of PET fibers was about 9 million metric tons and the annual world production of bottle resin was 1.2 million metric tons (1). Owing to the widespread use of PET, investigations of the decomposition ...

Linear economy models are no longer acceptable for the plastic industry and a change to sustainable circular must take place. In field of thermoplastic foams, biopolymer poly(lactic acid) (PLA) is suitable alternative fossil based foams like polystyrene. However, production PLA bead still challenge. regards products, reduction needed polymer additives aspired simplify union end-of-life streams....

2-hydroxypropyl-β-cyclodextrin (HP-β-CD) microfibres with diameters ranging between 3 and 7 µm were prepared by aqueous solution based high-speed electrospinning (HSES) technique then used as carbonising agent at wt% loading besides 15 ammonium polyphosphate (APP) to obtain flame-retarded poly(lactic acid) (PLA) composites. The high specific surface area of the microfibrous HP-β-CD was found ha...

Abstract Supercritical CO 2 -assisted extrusion technique was used to produce flame retarded foams from recycled poly(ethylene terephthalate) (rPET). Synergistic combination of aluminium-alkylphosphinate retardant (FR) and natural montmorillonite (MMT) utilised provide adequate retardancy at moderate loadings, i.e. with less than 9% additives. Addition FR found increase the rate degradation dur...

Highly loaded polymer/clay nanocomposites with layered structures are emerging as robust fire retardant surface coatings. However, time-intensive sequential deposition processes, e.g. layer-by-layer strategies, hinders obtaining large coating thicknesses and complicates an implementation into existing technologies. Here, we demonstrate a single-step, water-borne approach to prepare thick, self-...
