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.

期刊介绍： Green Chemistry is a journal that provides a unique forum for the publication of innovative research on the development of alternative green and sustainable technologies. The scope of Green Chemistry is based on the definition proposed by Anastas and Warner (Green Chemistry: Theory and Practice, P T Anastas and J C Warner, Oxford University Press, Oxford, 1998), which defines green chemistry as the utilisation of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and application of chemical products. Green Chemistry aims to reduce the environmental impact of the chemical enterprise by developing a technology base that is inherently non-toxic to living things and the environment. The journal welcomes submissions on all aspects of research relating to this endeavor and publishes original and significant cutting-edge research that is likely to be of wide general appeal. For a work to be published, it must present a significant advance in green chemistry, including a comparison with existing methods and a demonstration of advantages over those methods.
