Plasma polymerization is a process in which the polymerization reaction is initiated by plasma, which is usually used to modulate the surface chemistry of biomaterials by selective deposition of biomolecules or functional radicals.

Plasma polymerization takes place in a low pressure and low temperature plasma that is produced by a glow discharge through an organic gas or vapor.

2024年4月29日 · Plasma polymerization is a transformative technology capable of processing a wide spectrum of monomers, ranging from organic to inorganic, to create polymers with exceptional properties.

Plasma polymerization is a simple, one step process that can be used to apply a thin, uniform film as a protective coating which requires no curing or the use of any solvents.

Several reaction mechanisms have been proposed for the formation of plasma polymers, such as monomer fragmentation followed by poly-recombination into randomly structured and crosslinked films; fragmentation, accompanied by the formation of acetylene or other film-forming intermediates and deposition of polystyrene-like material; plasma ...

Yasuda’s models, Rapid Step-Growth Polymerization (RSGP) and Competitive Ablation Polymerization (CAP), are explained as fundamental mechanisms underpinning plasma-assisted deposition and polymerization processes.

Here, we briefly summarise the principles at the basis of plasma deposition and highlight recent progress made in understanding the unique chemistry and reactivity of these films. We then demonstrate how carefully designed plasma polymer films can serve the purpose of fundamental research and biomedical applications.

2023年6月16日 · Adhering to green chemistry principles, biobased precursors have recently shifted into the focus of research interests. This review gives an overview of the main biogenic substance classes that have been used for the deposition of plasma polymer coatings, including natural oils, terpenes, enzymes, and lactic acid-based precursors.

Plasma polymerization refers to the formation of polymeric materials by using either the plasma state of monomers, or reactive species created in the plasma state. Plasma is the fourth state of matter, consisting largely of ionized gas which maintains overall electrical neutrality.

2022年10月18日 · Plasma polymerization, starting from gaseous monomers, allows a whole new family of surface chemistries to be created. These processes have many exciting applications in the biomedical field due to the control they give on …
