“…According to Young’s equation and as mentioned above, the solid–liquid interfacial tension of SFDC should be significantly smaller than that of SFDC-L. It is generally accepted by current researchers that the solid–liquid interfacial tension tends to be smaller when the liquid phase exhibits superior wettability on the surface of the solid. − Therefore, we conclude that SFDC has better wettability than SFDC-L for the PTFE materials.…”

This article reports the synthesis of a novel sulfonated fluorocarbon surfactant (SFDC) containing double C 6 perfluorinated branched short chains and compares its surface properties with a similar structured compound (SFDC-L) in solutions. The critical micelle concentration (CMC) and the corresponding surface tension (γ CMC ) of SFDC aqueous solution are 9.77 × 10 −3 mmol/L and 22.15 mN/m, respectively, indicating that SFDC has excellent surface properties. Besides, the addition of nhexyltrimethylammonium bromide (HTAB) could further enhance the surface properties of SFDC. Meanwhile, the micellization, aggregation behavior, wettability, and adsorption at the air−water interface of SFDC and SFDC/HTAB mixture aqueous solutions are systematically investigated. Both SFDC and SFDC/HTAB show excellent wettability at low concentrations. The aggregation of SFDC and SFDC/HTAB mixtures in aqueous solution could be clearly seen as vesicles and rod-like micelles on TEM micrographs.

“…The observed difference between the theoretical and experimental molecular masses of the polymer is possibly due to the GPC calibration. 26,40,45 The change in wettability of the samples upon surface modification was also evaluated using water contact angle measurements (Figure 1). As the cleaned glass substrates have hydrophilic −OH groups, as expected, they demonstrated a very low contact angle of ∼3°(Supporting Information, Figure S3).…”

“…The interface-mediated RAFT polymerization technique has attracted great attention because it allows the fabrication of polymer brushes with controlled molecular weights and distributions. − To this end, the thermoresponsive PDEGMA brushes with thiol end groups were first synthesized on glass substrates via the interface-mediated RAFT polymerization technique (Scheme ). Prior to the polymerization step, the substrates were cleaned and activated to form −OH end groups.…”

Molecular sensing based on plasmonic materials is of great interest not only for basic scientific research but also for real-life applications. For plasmonic sensing, tunable hot-spot generation, in which the electromagnetic field is maximized, plays a key role. Herein, we developed a platform consisting of a thermoresponsive polymer brush with colloidal plasmonic particles and 3-D ordered/vertically aligned gold nanorod (AuNR) arrays for surface-enhanced Raman spectroscopy (SERS) applications. Poly(di(ethylene glycol) methyl ether methacrylate) brushes were synthesized via the interface-mediated reversible addition fragmentation chain transfer polymerization method. 3-D AuNR arrays were also fabricated by the oblique angle physical vapor deposition method. Highdensity hot-spot generation on the platforms was achieved by reducing the distance between the plasmonic particles and the underlying AuNR array as a result of phase transition of the polymer brushes. The design and optimization of such a platform will pave the way for molecular detection applications in a broad range of fields such as medicine, environmental protection, food safety, and homeland security.

“…Graft copolymers consist of randomly branched monomer side chains between linear polymer backbones . Graft copolymerization of MMA has been employed by researchers in the past to tailor the interfacial properties between the layers of different materials. , One of the commonly used synthetic methods for producing graft copolymers is via the “macromonomer” technique. The surface modification of common synthetic polymers can be done in a facile manner by this technique.…”

The recent advancements of poly(methyl methacrylate) (PMMA) as a transparent flexible polymer material have been utilized in numerous areas of engineering and materials science. PMMA-based copolymers demonstrate outstanding mechanical and optical properties owing to high transparency, lightweight nature, high impact resistance, and stress relaxation across glass transition temperature. These copolymers have unique characteristics of retaining optical and microstructural integrities during successive bending or elongations which make them an attractive choice for materials of stretchable electronics. In particular, there has been an escalated rise in the use of methyl methacrylate (MMA)-based transparent and stretchable copolymer films during the recent decades. Therefore, we have highlighted these recent developments into a comprehensive review in order to aid the future progress in these diverse fields. Herein, we have highlighted the scope of MMA as an important building block for the synthesis of highly transparent and flexible materials. The synthetic pathways of these copolymer materials and the resulting mechanical properties have been discussed. Moreover, the immense scope of these copolymer films has been highlighted by virtue of their applications in various industries.
