Magnetic Graphene Composites: From Rational Synthesis, Structural Design to Multifunctional Applications

Area of Science:

• Materials Science
• Nanotechnology
• Composite Materials

Background:

• Magnetic graphene composites (MGCs) are versatile materials with applications in environmental, biomedical, electromagnetic, and energy fields.
• A systematic framework connecting MGC synthesis, structure, properties, and applications is currently lacking.
• This review aims to bridge this knowledge gap by proposing an integrated design paradigm.

Purpose of the Study:

• To establish a comprehensive
• synthesis-structure-property-application
• design paradigm for magnetic graphene composites (MGCs).
• To provide a rational framework for selecting synthesis strategies and controlling structural properties for targeted applications.
• To guide the on-demand fabrication of MGCs for enhanced performance.

Main Methods:

• Development of a four-tier evolutionary framework for synthesis strategies, from modular assembly to molecular-scale co-conversion.
• Analysis of core structural regulation strategies: interface engineering, defect/doping engineering, and hierarchical construction.
• Case studies across environmental remediation, biomedicine, electromagnetic interference shielding, and energy storage applications.

Main Results:

• A synthesis decision-making tool enabling rational strategy selection based on desired microstructures.
• Demonstration of how structural control synergistically tailors MGC properties.
• Quantitative evidence of performance breakthroughs in diverse applications driven by targeted structural design.

Conclusions:

• The proposed paradigm facilitates a shift from "functional combination" to "performance synergy" in MGCs.
• Highlights future directions including dynamic intelligent systems, sustainable manufacturing, and data-driven design.
• Provides a theoretical framework and practical roadmap for predictive, design-driven MGC science.
