Super‐Hydrophobic Coatings Prepared by RF Magnetron Sputtering of PTFE

Abstract

Fluorocarbon plasma polymer films were prepared by RF magnetron sputtering in Argon from a balanced magnetron equipped with polytetrafluoroethylene (PTFE) target. Depending on the deposition conditions, primarily on the working gas pressure and distance between the target and the substrate, plasma polymer films were obtained with distinctly different chemical composition and/or morphology, as measured by means of XPS, FTIR and AFM. These films possessed static contact angle of water values ranging from 112° to ≈170° i.e. their behaviour ranged from hydrophobic to superhydrophobic ones.

Comparison of magnetron sputtering and gas aggregation nanoparticle source used for fabrication of silver nanoparticle films

“…The selection of these two materials was made on the basis of previous works that indicated that fluorocarbons have, in contrast to sputtered nylon that is rich in oxygen and nitrogen functional groups, very low condensation coefficient for metal atoms [31]. The deposition of these two plasma polymers was performed in plasma reactors described in more detail in previous studies [32,33]. RF planar, water cooled magnetron equipped with either PTFE or nylon 6,6 target, both sourced from Goodfellow, was used in both cases.…”

Core@shell Cu/hydrocarbon plasma polymer nanoparticles prepared by gas aggregation cluster source followed by in‐flight plasma polymer coating

“…The latter enabled production of complex functional nanocomposite or nanostructured materials with different architectures including classical nanocomposites or multi‐layered structures, coatings with dual‐scale roughness, or materials with horizontal gradients of NPs embedded into a matrix material . Furthermore, the GAS systems were proved to be highly flexible also in terms of composition of produced NPs as they enabled fabrication of metallic, metal‐oxide as well as polymeric NPs …”

Anti-icing performance in glaze ice of nanostructured film prepared by RF magnetron sputtering

“…In the past, many researchers have tried to improve the hydrophobicity of solid film by radio frequency (RF) magnetron sputtering [19]. Barshiilia et.al prepared three types of ZnO based coatings and analyzed the effect of surface morphology on the wettability [20].…”
