“…Similar to the influence of the substrate, an analogous electron withdrawing effect was present during the co‐polymerization of SO 2 with fluoro‐benzene and co‐polymerization of trifluoromethanesulfonic acid and chlorotrifluoroethylene . The inclusion of perfluorobenzene promoted the generation of higher oxidation state sulfur moieties (168–169 eV) while pentafluorobenzene produced sulfur moieties of lower binding energy (166 eV) .…”

This review surveys low‐pressure plasma‐based methods for producing hydrophilic and hydrogel‐like bio‐interface coatings without reactive functional groups in aqueous media. The main focus of the review is one‐step plasma polymerization; other plasma‐based methods such as plasma with grafting are also discussed within the context of monomers used, process development, ageing properties, and interaction of these coatings with proteins and cells. Coatings containing polyethylene glycol (PEG) or polyethylene oxide (PEO), acrylamides such as N‐isopropylacrylamide (NIPAM), and sulfonate (SO3) or sulfate (SO4) moieties are reviewed here.

“…The cross‐linking network of plasma polymerized membranes gives them a good thermal and chemical stability and a low permeability to organic liquids. Various fluorocarbon and hydrocarbon backbone monomers were copolymerized (e.g., trifluorochloroethene, hexafluoropropylene, hexafluorobenzene, butadiene, styrene…) with for example trifluoromethane sulfonic acid, sulfur dioxide, or phosphonic acid 11–17. Among those ones, we can note researches made by Roualdès et alwho used a mixture of styrene and trifluoromethane sulfonic acid (CF 3 SO 3 H) monomers for preparing proton conducting electrolyte membranes by plasma polymerization 18–23.…”

Thin sulfonated polystyrene films were prepared by high pressure PECVD of styrene and trifluoromethane sulfonic acid using a DBD. Argon or helium was used as carrier gas. The chemical composition of the pp‐sulfonated polystyrene was investigated by XPS, SSIMS, and FTIR. XPS shows that the content in sulfonated groups of the films deposited in the discharge can be tuned by varying the temperature of the acid monomer or by improving the HF voltage. Therefore, the films obtained are rich in ionizable groups (more than Nafion). TOF‐SSIMS and FTIR spectra allow to confirm the presence of sulfonic groups (observed on S2p XPS spectra) grafted in the polystyrene matrix.

“…[1][2][3][4] Recent advancements show that the plasma polymerization technique might be a good alternative, by which the problems mentioned above can be effectively addressed. [5][6][7][8][9] In most cases, however, the membranes synthesized by plasma polymerization techniques usually hold lower contents of proton exchange groups. The reason is that polymer membrane formation and degradation of monomers occur simultaneously in the process of plasma polymerization.…”

“…10,11 Therefore, it is not easy to introduce functional groups with higher contents, such as ion-exchange moieties, into the polymer membranes. [5][6][7] Here, we adopted an improved plasma polymerization technique, e.g. an after-glow discharge (AGD) technique, to prepare highly sulfonated ultra-thin proton-exchange membrane.…”

Sulfonated ultra-thin proton-exchange polymer membrane carrying pyridine groups was made from a plasma polymerization of styrene, 2-vinylpyridine, and trifluoromethanesulfonic acid by after-glow capacitively coupled discharge technique. Pyridine groups tethered to the polymer backbone acts as a medium through the basic nitrogen for transfer of protons between the sulfonic acid groups of proton exchange membrane. It shows that the method using present technology could effectively depress the degradation of monomers during the plasma polymerization. Spectroscopic analyses reveal that the obtained membranes are highly functionalized with proton exchange groups and have higher proton conductivity. Thus, the membranes are expected to be used in direct methanol fuel cells. Surf. Rev. Lett. 2009.16:297-302. Downloaded from www.worldscientific.com by CAMBRIDGE UNIVERSITY on 02/03/15.
