Free‐Radical Polymer‐Derived Cr 2 GaC/C and V 2 PC/C MAX Phase Composites

ABSTRACT Cr 2 GaC/C and V 2 PC/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 m 2 g − 1 for the Cr 2 GaC/C and V 2 PC/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.
