This book provides an overview of the latest scientific developments and technological advances in two-dimensional (2D) nanomaterials for fire-safe polymers. It summarizes the preparation methods for diverse types of 2D nanomaterials and their polymer composites and reviews their flame-retardant properties, toxic gas and smoke emission during combustion, and inhibition strategies. Covers fundamental aspects like influence of size and dispersion of 2D nanomaterials to help readers develop efficient, multi-functional, and ecofriendly fire-safe polymer composites for a wide range of applications Discusses new-emerging 2D nanomaterials for fire-safe polymer applications, including MXenes, graphitic carbon nitride, boron nitride, and black phosphorus Introduces basic modes of flame retardant action of 2D nanomaterials, including smoke and toxic gas suppression, and the role of 2D nanomaterials in promoting char formation This book is suitable for both scholars and engineers in the fields of polymer science and engineering. It is also aimed at graduate students in chemistry, materials, and safety science and engineering.
