Considerable effort has been made to improve ion-exchange membrane (IEM) properties in order to achieve better performance of IEM-based processes in various applications. Surface modification is one of the effective ways to improve IEM properties. Various methods have been used to modify IEM surfaces, for example, plasma treatment, polymerization, solution casting, electrodeposition, and ion implantation. These methods are able to produce a thin and fine distributed layer and also to modify the chemical structure of the surface. The new layer can be adsorbed, deposited, or chemically bonded on a membrane surface. By using these methods, IEM properties are improved, and the desired or specific characteristics such as high monovalent ion permselectivity, low fuel crossover, and anti-organic-fouling property can be obtained. In this paper, methods for surface modification of IEMs are reviewed. Moreover, the effects of modification on IEM properties and performance are discussed.

“…For example, if the plasma-forming gases are hydrocarbons or fluorinated organic compounds, a solid, chemically stable polymer film containing no functional groups is deposited on the surface of the membrane [63][64][65][66][67][68]. In this case, hydrophobic composite membranes with enhanced mechanical and chemical strength are produced.…”

The results of investigations into the use of low-temperature plasma for modification of polymer membranes are considered. The basic lines of research in this area are highlighted. It is shown that plasma treatment is quite an effective tool for both improving properties of existing polymer membranes and manufacturing new composite membranes with unique characteristics. Examples of successful use of plasmamodified membranes in various branches of industry and medicine are given.

“…Indeed, these membranes have high proton conductivity, but their great disadvantage is too high permeability of methanol molecules that migrate from anode to cathode lowering the cell performance. Deposition of a thin plasma polymer film, produced by PECVD from perfluoroheptane (C 7 F 16 ), on the membrane surface decreases the methanol permeability by two-orders of magnitudes (Lue et al, 2007).…”
