Substantial WebOct 13, 2024 · In this technique, a low-pressure glow discharge plasma is generated. The sample material is polarized negatively and acts as a cathode. The cations in the plasma are accelerated toward the sample surface and kicks-out the surface atoms. This bombardment process, referred to as sputtering, ablates the sample in the direction …
Plasma polymerization (or glow discharge polymerization) uses plasma sources to generate a gas discharge that provides energy to activate or fragment gaseous or liquid monomer, often containing a vinyl group, in order to initiate polymerization. Polymers formed from this technique are generally highly branched and highly cross-linked, and adhere to solid surfaces well. The biggest advantage to this process is that polymers can be directly attached to a desired surface while the chains ar…
