Synthesis of Polystyrene Thin Films by Means of an Atmospheric-Pressure Plasma Torch and a Dielectric Barrier Discharge

Challenges in the characterization of plasma polymers using XPS

“… Since SIMS enables the differentiation of fully-saturated and corresponding unsaturated fragments, by using bare and crosslinked conventional polystyrene (PS) as references, Merche et al could associate the degree of unsaturation of pp-PS observed by ToF-SIMS with crosslinking [93].…”

“… In the particular case of pp-polystyrene, a decrease in the aromatic C-H stretching vibration (3025 cm -1 ) versus aliphatic C-H stretching vibration (2930 cm -1 ) reveals ring opening and potentially more crosslinking [93,148]. One should mention that each of the aforementioned techniques has its own drawbacks and limits.…”

Deposition Kinetics and Thermal Properties of Atmospheric Plasma Deposited Methacrylate-Like Films

“…However, the concentration of middle-sized fragments in the active volume of the discharge during plasma deposition of AMA (C 3 H 5 þ and C 4 H 5 O þ ) and PiB (C 3 H 7 þ and C 4 H 7 O þ ) both tended to decrease. In literature, the chemical analysis of thin plasma films based on FTIR, XPS, [15,16] solid state 13 C NMR, [17] optical emission spectroscopy (OES), [18] electron spin resonance spectroscopy (ESR), [19,20] mass spectrometry, [21] and secondary ion mass spectroscopy (SIMS) [22][23][24] is predominant.…”

Organic Thin Film Transistors with Gate Dielectrics of Plasma Polymerized Styrene and Vinyl Acetate Thin Films

“…The lower surface energy of the ppS could be thought to be attributable to the higher density of the aromatic ring [6,7]. The AFM 3D-images of the 100 nm-thick layers of both ppS and ppVA grown on ITO are shown in Fig.…”
