Abstract Despite great advances for flame-retardant polyamide 6 (PA6), there is still a lack of facile strategies for creating advanced flame-retardant PA6 composites without significantly compromising its thermal stability to date. In this work, flame retardant PA6 nanocomposites were fabricated by incorporation of carbon nanotubes (CNTs) and organic montmorillonite (OMMT) together with aluminum diisobutylphosphinite acid (ABPA) into PA6. CNTs, exfoliated clay sheets and APBA particles are fine...
Abstract Flame retardant and self-extinguishing properties of composites are of importance to minimize heat release and smoke production during combustion for fire resistant polymer composites. This work presents intumescent flame retardant polyketone nanocomposites composed of multilayered expandable graphites incorporated with multi-walled carbon nanotubes. We observe a significant reduction of heat release rate, total heat release, and smoke production rate as the intumescent expandable graph...

In this study, inherently flame retardant nanocomposite nylon 6 fibers infused with nanoclay and intumescent additives were compounded and melt-spun. Two approaches were adopted to mitigate the loss of mechanical properties typically observed nanocomposite fiber systems: (a) additive particle size reduction; and (b) elastomer toughening of the nanocomposite system. As a result, the ductility of the FR nanocomposite formulations was improved significantly. Structural and morphological characteriz...
Two different types of organic montmorillonite, namely quaternary ammonium salt intercalated MMT (CMMT) and quaternary phosphonium salt intercalated MMT (PMMT) were used as fillers in the flame-retardant polyamide (PA6) based on aluminium salts of diisobutylphosphinic acid (ABPA). The influence of different types of organic montmorillonite (OMMT) on the structure and properties of flame-retardant PA6 nanocomposites were systematically investigated. The X-ray diffraction and transmission electron...
In this work, the effect of TiO2 addition over morphological and ultraviolet (UV) blocking properties of poly(lactic acid) (PLA) and poly(ɛ-caprolactone) (PCL) blends was investigated. The micrographs showed a partially co-continuous structure in the PLA/PCL blend with 42/58 (wt %/wt %) and the TiO2 nanoparticles addition leads to a structural phase inversion, i.e., continuous PCL and partially continuous PLA with a dispersed portion. TiO2 nanoparticles were observed to be preferably localized a...

Abstract This work explores the feasibility of using graphene as an effective synergist for intumescent flame retardant (IFR). The flammability test and fire behavior under different fire scenarios are investigated. The incorporation of graphene results in different responses of IFR/polypropylene (PP) composites to small fire tests and burning under forced-flaming condition. The addition of graphene weakens the reaction of flame retardant PP to small flame. Lower loading of graphene is observed ...
Abstract As an abundant and attractive element, the emergence of new carbon-based materials brings revolutionary development in material science and technology. Carbon-based materials have spawned considerable interest for fabricating polymer composites/nanocomposites with greatly improved mechanical, thermal, gas barrier, conductivity, and flame retardant performance. In this review, the importance of carbon-based materials and the necessity of fire resistance for polymeric materials are initia...
High-performance polystyrene-b-poly (ethylene-butylene)-b-polystyrene/thermoplastic polyurethane (SEBS/TPU) blends containing polyurethane blocked styrene–ethylene–butylene–styrene (SEBS-b-TPU) and SEBS-b-TPU/clay were obtained by melt mixing. The influence of SEBS-b-TPU and nanoclay content on morphology, mechanical, thermal, rheological and abrasion behavior of the SEBS/TPU blends were investigated. SEM results indicated that the domain size of the TPU phase was remarkably reduced by the prese...
