Transforming wastes into functional materials: natural cork-based physical structural components and polymers

Abstract

During the transition towards sustainable practices, cork has emerged as a pivotal material. Its distinctive cellular structure and chemical composition, encompassing suberin, lignin, cellulose, and extractives, underpin a multitude of properties. The honeycomb arrangement of cells confers upon cork advantages such as lightweightness, insulation, thermal regulation, and remarkable mechanical performance. Breakthroughs in nanotechnology have enabled precise modifications, broadening the scope of cork's applications beyond conventional uses. This review offers a comprehensive exploration of cork's natural structure and composition, with a focus on its intricate cellular arrangement and specialized suberin components. It elucidates the intricate interplay between cork's structure and properties, evaluating modification strategies and lifecycle impacts. Furthermore, the discussion extends to the realm of functional polymers and structural components derived from cork, underscoring the potential for designing eco-friendly materials. Ultimately, this review aims to catalyze future research endeavors geared towards the sustainable utilization of cork in tackling global challenges, emphasizing the crucial nexus between structure, assembly, and function.
