“…In this approach, nanometric scale particles are added to a macroscopic material to produce new properties (Laoutid et al 2009;Morgan and Gilman 2012;Sertsova et al 2010). Intumescent polymer-clay nanocomposites have been applied to protect polymers and steel (Laoutid et al 2009;Morgan and Gilman 2012), but studies for wood products are not known to the authors.…”

Flammability behaviour of wood and a review of the methods for its reduction

Wood is one of the most sustainable, aesthetically pleasing and environmentally benign materials. Not only is wood often an integral part of structures, it is also the main source of furnishings found in homes, schools, and offices around the world. The often inevitable hazards of fire make wood a very desirable material for further investigation. As well as ignition resistance and a low heat release rate, timber products have long been required to resist burnthrough and maintain structural integrity whilst continuing to provide protection when exposed to fire or heat. Various industry standard tests are thus required to ensure adequate protection from fire is provided. When heated, wood undergoes thermal degradation and combustion to produce gases, vapours, tars and char. In order to understand and alter the fire behaviour of wood, it is necessary to know in as much detail as possible about its processes of decomposition. Various thermal analysis and flammability assessment techniques are utilised for this purpose, including thermogravimetric analysis, cone calorimetry and the single burning item test. The results of such tests are often highly dependent on various parameters including changes to the gas composition, temperature, heating rate, and sample shape size. Potential approaches for fire retarding timber are reviewed, identifying two main approaches: char formation and isolating layers. Other potential approaches are recognised, including the use of inorganic minerals, such as sericrite, and metal foils in combination with intumescent products. Formulations containing silicon, nitrogen and phosphorus have been reported, and efforts to retain silicon in the wood have been successful using micro-layers of silicon dioxide. Nano-scale fire retardants, such as nanocomposite coatings, are considered to provide a new generation of fire retardants, and may have potential for wood. Expandable graphite is identified for use in polymers and has potential for wood provided coating applications are preferred.

As a versatile star product, poly(vinyl chloride) (PVC) has kept active in our daily life all through since it was invented. However, the severe fire hazard and heavy smoke produced during combustion, particularly the extensively used flexible PVC products, have been puzzling manufacturers and researchers for ages. Over the last decade, multifarious flame retardants and smoke suppressants were developed for PVC materials. In this review, combined literature with the results based on the research from our group, recent emerged flame retardants and smoke suppressants for PVC are introduced. Meanwhile, the flame retardant mechanisms and experimental analysis results are described to understand the relationship between characters of flame retardants (including chemical compositions, structures or morphologies) and fire performance of the composites. The potential substitutes for traditional harmful flame retardant antimony trioxide are discussed aiming to the emphasis on increasing prominent environmental concerns. In particular, one section is dedicated to new approaches for the preparation of novel environmentally friendly and high-efficiency flame retardants. It is hoped that this review will not only summarize the new emerged flame retardants and smoke suppressants for PVC, but also provide the new trend to prompt sequent exploration in both academic research and industrial application.

Two different types of calcium fluoride particles (approximate to 325 nm), one of them surface modified using a long-chain organophosphorous reagent, were incorporated into a poly(ethylene terephthalate) (PET) matrix. The CaF2 particles were synthesized by a simple chemical precipitation method. To modify the particles surface, a heat treatment using Cyanex((R)) 921 [tri-n-octylphosphine oxide (TOPO)] dissolved in isopropanol, was carried out. Therefore, unlike the as-synthesized particles, the modified particles contained an amount of TOPO. The composite materials were prepared by melt-blending PET and particles at different filler loadings. The influence of the particles surface modification on the nonisothermal crystallization behavior of PET was investigated by using differential scanning calorimetry and field emission scanning electron microscopy. The Jeziorny-modified Avrami equation was applied to describe the crystallization kinetics and several parameters were analyzed (half-crystallization time, Avrami exponent, and rate constant). According to the results, the fluorite particles act as nucleating agents, accelerating the PET crystallization rate. However, the effect on the polymer crystallization rate was more noticeable with the addition of the nonmodified particles where the surface might play an important role for epitaxial crystallization, while the addition of the particles, with an organic coating layer on the surface, resulted in a crystallization behavior more similar to the observed for neat PET.
