MXenes are a new family of two-dimensional (2D) metal carbides, having properties such as metallic conductivity and hydrophilicity. Adding polymer binders/spacers between atomically thin MXene layers or reinforcing polymers with MXenes results in composite films that have excellent flexibility, good tensile and compressive strengths, and electrical conductivity. This book covers all advances in the field of MXene-filled polymer nanocomposites to date, illustrating fabrication and characterization, and specific properties like anti-healing, anti-friction, and microwave absorption. It further covers potential applications like energy conversion, storage systems, antibacterial, and drug delivery. The book features: exclusive material on MXene-based polymer nanocomposites properties and potential applications of polymers upon addition of MXenes the effect of MXenes on various thermoplastic and elastomer polymers a focus on the properties, fabrications methods, and applications of relevant polymer matrices; and extensive coverage of the role of MXenes in polymers This book is aimed at researchers, professionals, and graduate students in material science, polymer engineering, electronic materials, composites, chemical processing, chemical sciences, fire engineering, and biomedicine.
