Machine learning-driven material intelligence research and development

Machine learning (ML) is transforming materials research and development (R&D), driving a fundamental shift from experience-driven approaches to data-driven frameworks. This review systematically highlights the transformative breakthroughs brought by machine learning throughout the entire process of intelligent material innovation. And it provides a comprehensive full chain analysis, from atomic scale design to macroscopic applications, emphasizing multi-scale modeling that combines physical mechanisms with data-driven methods, running through all stages of material innovation. In the design phase, ML promotes performance-oriented structural optimization through inverse design systems and generative models. For synthesis and processing, closed-loop autonomous systems and green controllable synthesis strategies significantly improve efficiency and sustainability. In terms of advanced representation, ML-powered techniques can help proactively tackle key challenge of complex structures. Performance prediction models enable precise correlations between material properties and extreme properties (such as auxiliary structures), by revealing catalytic descriptors and decoding biological interface mechanisms. Ultimately, these ML-driven advances are unlocking practical applications in key fields, such as energy, biomedicine, environmental remediation, and structural engineering. This article aims to provide a comprehensive technological roadmap for the next generation of smart material development by integrating cross scale insights and autonomous strategies, and to outline future directions for this rapidly developing paradigm.
