Graphene nanoribbon synthesis and properties in polymer composites: A review

Graphene nanoribbons (GNRs), including polymer composites, have recently received much interest owing to their unusual features and future uses in various industries. The production strategies and characteristics of GNRs in polymer composites are summarized in this paper. Their synthesis is crucial in getting the appropriate qualities and modifying the dimensions of GNRs. Top-down and bottom-up are the two broad ways that have been utilized for the formation of GNRs. Concerning scalability, dimension control, and cost-effectiveness, each method has its own set of pros and cons. The strengths and weaknesses of the various synthesis methods are discussed to illuminate the present state of the art. GNRs possess distinctive electrical properties, a substantial surface area, robust mechanical strength, and efficient thermal conductivity, making them very suitable for enhancing the overall efficacy of polymer composites. Polymer matrices may benefit from GNR changes; the general characteristics of the composites by the distribution and orientation of GNRs inside the polymer matrix. Energy storage, sensors, biomedical applications, and corrosion protection are possible uses for GNR-based polymer composites, which are also discussed. This review focuses on the latest developments and potential of polymer composites based on GNR for these applications.
