Plasma‐Enabled Polymerisation: From Non‐Thermal Plasma Characteristics, Platforms and Mechanisms to Functional Materials, Advantages and Constraints

This is the authors' abstract. We don't add key points for this paper.

Non‐thermal plasma‐enabled polymerisation is an emerging strategy in which non‐equilibrium plasma activates precursors, sustains polymer growth or drives post‐discharge polymer‐forming reactions. This review links plasma physicochemical characteristics and reactor platforms to precursor‐specific activation, growth‐relevant species, fragmentation–association balance, network formation and material function. Products span biofunctional and regenerative materials, antimicrobial and therapeutic systems, membranes and water‐retentive porous materials, sorbents, remediation media, and sensing and electronic materials. Distinctive capabilities include low‐thermal‐load processing, reduced reliance on added initiators, expanded precursor space, non‐conventional polymeric structures, processing versatility and spatial and temporal tunability. Key constraints are predictability, structural ambiguity, conditional precursor suitability and process‐dependent sustainability.
