Modern polymer coatings possess tremendous multifunctionalities and have attracted immense research interest in recent decades. However, with the expeditious development of technologies and industries, there is a vast demand for the flame retardancy and electrical conductivity of engineered polymer coatings. Traditional functional materials that re...

This state‐of‐the‐art review is geared toward elucidating the molecular understanding of the carbon‐based flame‐retardant mechanisms for polymers via holistic characterization combining detailed analytical assessments and computational material science. The use of carbon‐based flame retardants, which include graphite, graphene, carbon nanotubes (CN...

Given the growing demand for increased energy capacity and power density in battery systems, ensuring thermal safety in lithium-ion batteries has become a significant challenge for the coming decade. Effective thermal management plays a crucial role in battery design optimization. Air-cooling temperatures in vehicles often vary from ambient due to...

To date, zinc-ion batteries (ZIBs) have been attracting extensive attention due to their outstanding properties and the potential to be the solution for next-generation energy storage systems.

Carbon derived from peanut shell (CPS) with 2D structure has been proved to own sufficient thermal stability and is a promising flame retardant (FR) additive for EP in our previous work. To further explore the feasibility of implementing CPS into the intumescent fire retardant (IFR) system, a novel green IFR system was first proposed in this study....

Demand for underground railways has rapidly increased due to accelerated urbanisation and population growth. This has elevated the importance of tunnel designs with adequate fire safety and protection measures. However, due to intricate modern rail tunnel designs, prescriptive codes are often difficult to implement and lead to over-conservative des...

A new predictive fire suppression model has been developed and applied to a compartment room environment with various fire locations to clarify the suppression mechanisms of water mist and sprinkler systems.

The oxidation of graphene-based material (i.e. graphite, graphene) is a reaction of immense importance owing to its extensive industrial application (i.e. nanocomposites, flame retardants, energy storage). Although immense experimental works were carried out for identifying the thermal degradation and oxidation process of graphene, they generally l...

Understanding and characterisation of the pyrolysis and burning behaviour of flame retardant (FR) polymers are essential towards optimising the end-product in terms of flammability, charring, toxicity and smoke reduction. This study proposes a modelling framework to study the combustion behaviour, pyrolysis kinetics and FR mechanisms of FR treated...

Combustibility of insulation and external façade remains a critical issue for many countries as they are commonly found in modern building structures. While standardised fire tests can be carried out to examine the flammability limits of building polymers, they cannot inform us of the toxicity and smoke productions of the underlying materials. With...

Building polymers implemented into building panels and exterior façades have been determined as the major contributor to severe fire incidents, including the 2017 Grenfell Tower fire incident. To gain a deeper understanding of the pyrolysis process of these polymer composites, this work proposes a multi-scale modelling framework comprising of apply...

Aqueous suppression systems (i.e. fire sprinkler, water mist) have been extensively utilised for compartmental fire suppression due to their significant heat extraction ability. Nevertheless, challenges can be foreseen in suppressing water-reactive chemicals as a violent explosive reaction will be triggered, such as alkali metals (i.e. Na, Li) and...

Biomass-derived carbon has been recognised as a green, economic and promising flame retardant (FR) for polymer matrix.
