Plasma polymerization using helium atmospheric‐pressure plasma jet with heptylamine monomer

Abstract

Atmospheric‐pressure plasma jets can be used to modify surfaces in a spatially‐defined manner. Operating these jets in air is an efficient surface modification tool, however the resulting surface chemistries are limited by the plasma gases. In this study we demonstrate that plasma polymerization with heptylamine on polystyrene (PS) surfaces, using an atmospheric pressure plasma jet (APPJ), can enable mammalian cell attachment and growth. Importantly, the addition of the heptylamine monomer, in a helium carrier‐gas, altered the spatially‐defined treatment area in comparison to treatment with a helium plasma alone.

A Review of Plasma Synthesis Methods for Polymer Films and Nanoparticles under Atmospheric Pressure Conditions

“…Materials in a gaseous state at room temperature are themselves applied as precursors, whereas materials that exist as liquids are mainly introduced to a plasma region as an aerosol via atomizing or bubbling with gas. GATP methods are commonly used for the deposition of polymer films [ 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 , 74 , 75 , 76 , 77 , 78 , 79 , 80 , 81 , 82 , 83 , 84 , 85 ], as this method allows in-line processing by moving either the APP devices or the substrates [ 39 ].…”

“…Helium gas (He) used for plasma discharge was introduced in the downstream flow, and heptylamine aerosol was bubbled by the He introduced into the stream via a branch off the quartz body ( Figure 2 e). The supplied power was a sinusoidal current with a voltage of 8 kVp–p and a frequency of 10 kHz [ 55 ].…”

One-Step Liquid Phase Polymerization of HEMA by Atmospheric-Pressure Plasma Discharges for Ti Dental Implants

“…Plasma polymerization has been widely used as a process for preparing biocompatible coatings, but until recently, the application was limited mostly to low-pressure plasma polymerization [32][33][34] or, alternatively, with atmospheric pressure plasma polymerization [35][36][37]. In the latter, either dielectric barrier discharges or plasma jets are employed, introducing monomers in the discharge by producing an aerosol which was led by the gas flow toward the surface of the material [38].…”
