“…Since this review specifically focuses on polymer coatings, this section briefly discusses some of the main coating methods used for biopolymer coatings. The assembly of polymer into coatings and films can be done various methods such as layer by layer (LBL) [ 3 , 4 ], polymer brushes, dip coating, Langmuir-Blodgett (LB) [ 4 , 5 , 6 ], plasma based coating methods, spin coatings and hydrogels. In LBL method, positively and negatively charged polyelectrolytes are coated successively.…”

“…In LBL, molecules from the bulk solution are coated on the substrate, whereas in LB, molecules from the solution surface are coated on the substrates. Leontidis described about LB films and compared it with LBL method [ 5 ]. Polymer brush is another popular and interesting surface modification technique in which soft material is covalently tethered on the surface of the substrate [ 7 ] and has potential applications in various fields.…”

“…Due to the fact that this analysis concentrates solely on polymer coatings, this part will offer a concise discussion of some of the most common coating processes that are utilized for biopolymer coatings. Layer by layer (LBL) [1,2], Langmuir-Blodgett (LB) [2,38,39], dip coatings, plasma-based coating technologies, polymer brushes, spin coatings, and hydrogels are some of the other ways that may be used to assemble polymer into coatings and films. During the LBL process, successive coatings of polyelectrolytes are applied that are positively and negatively charged.…”

Fabrication of a Self-Supported Nanoparticle-Decorated Amphipathic Film at a Liquid/Liquid Interphase

et al. 2017

The design and facile fabrication of an amphipathic, mechanically durable, nanoparticle (NP)-decorated film has been realized at a liquid/liquid interphase. The innovative film is prepared by applying a changing electric field across an organic-aqueous interphase in the presence of 1-2 nm metal NPs, with a specific focus on Ir NPs in this work, self-assembled at the interphase, where the organic phase consists of a dissolved hydrophobic polymer in a volatile solvent. The electrochemical process leads to the oxidation of the Ir to IrOx, forming a hydrous oxide matrix at the interphase. With evaporation of the residual volatile solvent and precipitation of the polymer backbone, an isolable Ir/IrOx-decorated film is realized. The novelty of this technique stems from the ability to fabricate a substrate material in situ around a nanoparticle matrix, as opposed to transferring the matrix onto a substrate. The subsequent film exhibits a hydrophobic and a hydrophilic surface, permitting the film to reside at a water/oil, water/air, or oil/air interphase. The differences in wettability are attributed to the differences in the chemical and physical properties of the two sides of the film. Interestingly, despite both sides of the film exhibiting different wettabilities, both sides are electrochemically accessible. Several potential applications exist for this film, including the separation and collection of oil from water, in biosensors, and as catalyst layers.
