Quelques avantages de la polymérisation induite par un plasma froid microonde

Plasma induced polymerizations using an RF (13,56 MHz) or a microwave (433 MHz) generator were compared. The microwave plasma induced polymerization of a multifunctional acrylate (3‐ylomethylpentamethylene triacrylate) (trimethylolpropane triacrylate) (1) was studied as a function of different macroscopic parameters (chemical nature of gas, time, discharge power, distance between the surfatron and the substrate etc.). The involved mechanisms were found to be similar to those in the RF plasma. One of the advantages of the microwave apparatus is the possibility of working in the post‐discharge regime with selected reactive species. Evidence of the chemical structure of the polymer at its surface is given by ATR‐FTIR spectroscopy.
