“…Generally, LDHs containing Mg and Al metal ions have been widely studied as catalysts in previous reports . The amount of oxygen‐containing groups on the LDH‐rGO increases comparing with the LDHs or GO, which accelerates the elimination of side‐groups at lower temperature . In addition, the maximum degradation rates decrease and the residues increase with the increase of the LDH‐rGO contents.…”

A hybrid layered double hydroxides (LDHs)‐reduced graphene oxide (rGO) material has been fabricated by the facile co‐precipitation method. The structural characterization and morphological observation of the composites suggest that small LDH‐rGO crystals are in situ grown on the surface of GO nanosheets, preventing the compact stacking of GO. The poly(vinyl alcohol) (PVA)/LDH‐rGO hybrid films with different contents of LDH‐rGO are prepared and investigated. The results show that the LDH‐rGO composites are homogeneous dispersed in PVA matrix based on scanning electron microscopy and transmission electron microscopy observations. The PVA/LDH‐rGO film exhibits significantly improved mechanical and barrier properties compared with those of the pure PVA film. POLYM.

“…Halogen-containing compounds are known as common flame retardants but under regulatory scrutiny for their toxicity and environmental persistence (Cao et al , 2011; Chen and Wang, 2010). Most academic research adapts the halogen-free and more environmentally friendly intumescent flame retardant (IFR) additives (Cao et al , 2011; Wang et al , 2007; Guo et al , 2011; Cai et al , 2020). However, modern IFRs have certain drawbacks such as a high loading ratio which decreases the mechanical properties of polymeric composites.…”

Purpose The purpose of this study is to review and summarise the existing available literature on lightweight cladding systems to provide detailed information on fire behaviour (ignitibility, heat release rate and smoke toxicity) and various test method protocols. Additionally, the paper discusses the challenges and provides updated knowledge and recommendation on selective-fire mechanisms such as rapid-fire spread, air cavity and fire re-entry behaviours due to dripping and melting of lightweight composite claddings. Design/methodology/approach A comprehensive literature review on fire behaviour, fire hazard and testing methods of lightweight composite claddings has been conducted in this research. In summarising all possible fire hazards, particular attention is given to the potential impact of toxicity of lightweight cladding fires. In addition, various criteria for fire performance evaluation of lightweight composite claddings are also highlighted. These evaluations are generally categorised as small-, intermediate- and large-scale test methods. Findings The major challenges of lightweight claddings are rapid fire spread, smoke production and toxicity and inconsistency in fire testing. Originality/value The review highlights the current challenges in cladding fire, smoke toxicity, testing system and regulation to provide some research recommendations to address the identified challenges.

“…In order to tackle this issue, some approaches have been conducted to improve these drawbacks, such as incorporation of nanocarbon materials [ 1 ], layered double hydroxides (LDHs) [ 2 , 3 ], metal–organic frameworks (MOFs) [ 4 , 5 ], nanoclay [ 6 , 7 ], and phosphorus-containing flame retardants [ 8 , 9 ]. Concerning the environmental friendliness and high-efficiency, intumescent fire retardants (IFRs) have been long-term developed and attracted numerous attentions to polymers [ 10 , 11 , 12 ]. Exolit AP750 (AP750) as a high efficiency intumescent flame retardant because of its machining stability, smoke suppressibility and non-toxic, is used in the following study.…”

We aimed to study the impact of surface modification of basalt fiber (BF) on the mechanical properties of basalt fiber-based epoxy composites. Four different types of pretreatment approaches to BF were used; then a silane coupling agent (KH550) was applied to further modify the pretreated BF, prior to the preparation of epoxy resin (EP)/BF composites. The combination of acetone (pre-treatment) and KH550 (formal surface treatment) for basalt fiber (BT-AT) imparted the EP/BF composite with the best performance in both tensile and impact strengths. Subsequently, such modified BF was introduced into the flame-retardant epoxy composites (EP/AP750) to prepare basalt fiber reinforced flame-retardant epoxy composite (EP/AP750/BF-AT). The fire behaviors of the composites were evaluated by vertical burning test (UL-94), limiting oxygen index (LOI) test and cone calorimetry. In comparison to the flame-retardant properties of EP/AP750, the incorporation of BF-AT slightly reduced LOI value from 26.3% to 25.1%, maintained the good performance in vertical burning test, but increased the peak of the heat release rate. Besides, the thermal properties and mechanical properties of the composites were investigated by thermogravimetric analysis (TGA), universal tensile test, impact test and dynamic mechanical analysis (DMA).
