Abstract

Cr₂GaC/C and V₂PC/C MAX phase composites were synthesized via a free-radical polymerization–pyrolysis route, achieving > 87 wt% crystalline MAX phase content. SEM/EDS confirms the expected 2:1 atomic ratios of Cr:Ga and V:P, while BET analysis reveals structures with specific surface areas of 344 and 282 m² g⁻¹ for the Cr₂GaC/C and V₂PC/C composites, respectively, which are attributed to the porous carbonaceous network. HAXPES verifies core-level signatures consistent with the targeted MAX phases. This approach demonstrates the versatility of sol–gel-derived free-radical polymer networks as reactive precursors for MAX phase formation. The method further provides a foundation for advanced processing strategies, including vat photopolymerization-based additive manufacturing of high-surface-area and complex MAX phase architectures.

期刊介绍： The Journal of the American Ceramic Society contains records of original research that provide insight into or describe the science of ceramic and glass materials and composites based on ceramics and glasses. These papers include reports on discovery, characterization, and analysis of new inorganic, non-metallic materials; synthesis methods; phase relationships; processing approaches; microstructure-property relationships; and functionalities. Of great interest are works that support understanding founded on fundamental principles using experimental, theoretical, or computational methods or combinations of those approaches. All the published papers must be of enduring value and relevant to the science of ceramics and glasses or composites based on those materials. Papers on fundamental ceramic and glass science are welcome including those in the following areas: Enabling materials for grand challenges[...] Materials design, selection, synthesis and processing methods[...] Characterization of compositions, structures, defects, and properties along with new methods [...] Mechanisms, Theory, Modeling, and Simulation[...] JACerS accepts submissions of full-length Articles reporting original research, in-depth Feature Articles, Reviews of the state-of-the-art with compelling analysis, and Rapid Communications which are short papers with sufficient novelty or impact to justify swift publication.
