Graphene sandwich structures have emerged as a versatile platform for advanced electrochemical, electronic and sensing devices owing to their tuneable interfacial physics and multilayer architectural synergy. Data for the analysis has been retrieved from the Web of Science core collection database, covering the period from 2004 to 2025, resulting in 949 documents. In this study a comprehensive keyword-based bibliometric analysis of graphene sandwich structures has been undertaken. Three complementary keyword analysis methods viz. keyword co-occurrence analysis, thematic mapping and factorial analysis have been used to uncover the intellectual structure and emerging trends of graphene sandwich structures. The co-occurrence network reveals dominant research clusters on mechanical reinforcement, energy storage, sensing, and multifunctional composites. Thematic map analysis provides deeper insight into the maturity and relevance of research themes by classifying them into motor, basic, niche, and emerging/declining themes. Factorial analysis further elucidates the conceptual relationships between keywords, enabling the classification of research directions into distinct knowledge domains. Vosviewer software is employed to generate the visualization maps and Biblioshiny was employed to quantify the structural prominence, bridging capacity and strategic influence of core keywords within the knowledge network analysis of the data through the network centrality indicators like betweenness, closeness and PageRank centralities. A key contribution of this work lies in systematically mapping these keyword clusters to their corresponding application potentials, followed by linking these applications to real-world products. This integrated framework provides valuable insights into the translational trajectory of graphene sandwich structures from fundamental research to industrial implementation, offering guidance for future research and innovation strategies.
