Deposition of Non-Fouling PEO-Like Coatings Using a Low Temperature Atmospheric Pressure Plasma Jet

Abstract

Plasma polymerised PEO‐like films were deposited from tetraethylene glycol dimethyl ether (TEGDME) and diethylene glycol vinyl ether (DEGVE) using an atmospheric plasma jet. Films formed from TEGDME with COC retention >50% showed anti‐fouling properties, while DEGVE films with COC >60% did not. TEGDME films deposited at higher monomer flow rates had a lower density and more amorphous phases in the polymer network. Consequently, these films more readily facilitate penetration and binding of water to their surface in comparison to the denser DEGVE films. The difference in fouling properties identified through this comparative study has shown that % COC retention may not alone be an indication of non‐fouling behaviour. Other factors such as polymer network structure may also play a crucial role in the prevention of surface fouling.

Deposition of Poly(Ethylene Oxide)‐Like Plasma Polymers on Inner Surfaces of Cavities by Means of Atmospheric‐Pressure SDBD‐Based Jet

“…For the 15 mm sample, the islands with A around 1.4 μm 2 prevail whereas for the 10 mm sample only large islands with A > 10 μm 2 are present (in the latter case, only a rough estimation of the histogram is provided because of the small number of islands that fit into the 15 × 15 μm AFM area). The island growth has never been reported before either for low pressure or for atmospheric pressure plasma deposited PEO‐like coatings, and is typical for the Ostwald ripening mechanism. Indeed, the large islands on the substrates closer to the exit orifice (at higher fluence of depositing species) are formed at the expense of the smaller ones that are formed at smaller fluences.…”

“…PEO is remarkable in its ability to withstand accumulation of biofilms in biological media (i.e., non‐fouling properties) and has often been suggested to be used for surface modification of biological fluid‐contacting devices . Our group utilised SDBD and APP jet for the preparation of non‐fouling PEO‐like plasma polymers from di(ethylene) glycol vinyl ether (DVE) on flat model surfaces . It was found that a smaller average power (<1.5 W) delivered to the discharge resulted in the deposition of the films with more than 60% retention of ethers.…”

Low Resistance–Integrated All‐Solid‐State Battery Achieved by Li7La3Zr2O12 Nanowire Upgrading Polyethylene Oxide (PEO) Composite Electrolyte and PEO Cathode Binder

“…The peaks at 291.0 and 282.3 eV are assigned to carbon atoms of C–F and C–S, possibly carbons in LITFSI salt. Whereas the C 1s spectra in PLLN appears a new peak at 285.4 eV, which is assigned to the C–N group, proving the formation of CN bond . The C–N group may result from the interaction between carbon atoms in PEO and nitrogen atoms in LITFSI.…”

Deposition of 2‐oxazoline‐based plasma polymer coatings using atmospheric pressure helium plasma jet

“…To enhance the OXpp coatings’ stability and substrate adhesion, the plasma polymerisation process was performed on heated substrates. This strategy was demonstrated through plasma polymerisation of silane and ethylene glycol precursors . The increase in the substrate temperature reduces the deposition rate by minimising the adsorption probability of radicals hitting the substrate.…”
