“…The signal for methyl protons of -OCH 3 (a) in MMA units appeared at 3.55 ppm [38,39]. The signals of -CH 3 protons were seen at 0.88-1.36 ppm in both MMA and HEMA units, while for methylene protons they were in the range of 1.5-2.1 ppm.…”

“…For both P(HEMA-co-MMA)-block-PPEGMA (2b, 2d) block copolymers, the 1 H-NMR spectrum exhibited signals originating from -CH 3 protons and -CH 2 protons between 0.84-1.4 ppm and 1.8-2.1 ppm, respectively, in both MMA and HEMA units [38], as depicted in Figure 5. The appearance of signals at 2.3-2.5 ppm and 3.38 ppm was attributed to -CH 2 and CH 3 O-protons arising from PEGMA units [39][40][41].…”

Synthesis of fluorinated amphiphilic block copolymers via atom transfer radical polymerization (ATRP) and Cu(I) catalyzed Huisgen 1,3-dipolar cycloaddition (CuAAC) was demonstrated. First, a PEGMA and MMA based block copolymer carrying multiple side-chain acetylene moieties on the hydrophobic segment for postfunctionalization was carried out. This involves the synthesis of a series of P(HEMA-co-MMA) random copolymers to be employed as macroinitiators in the controlled synthesis of P(HEMA-co-MMA)-block-PPEGMA block copolymers by using ATRP, followed by a modification step on the hydroxyl side groups of HEMA via Steglich esterification to afford propargyl side-functional polymer, alkyne-P(HEMA-co-MMA)-block-PPEGMA. Finally, click coupling between side-chain acetylene functionalities and 2,3,4,5,6-pentafluorobenzyl azide yielded fluorinated amphiphilic block copolymers. The obtained polymers were structurally characterized by 1 H-NMR, 19 F-NMR, FT-IR, and GPC. Their thermal characterizations were performed using DSC and TGA.

New hybrid poly(hydroxyethyl methacrylate-co-methyl methacrylate)-g-polyhedral oligosilsesquioxane [poly(HEMA-co-MMA)-g-POSS] nanocomposites were synthesized by the combination of reversible addition fragmentation chain transfer (RAFT) polymerization and click chemistry using a grafting to protocol. Initially, the random copolymer poly(HEMA-co-MMA) was prepared by RAFT polymerization of HEMA and MMA. Alkynyl side groups were introduced onto the polymeric backbones by esterification reaction between 4-pentynoic acid and the hydroxyl groups on poly(HEMA-co-MMA). Azide-substituted POSS (POSSAN 3 ) was prepared by the reaction of chloropropyl-heptaisobutyl-substituted POSS with NaN 3 . The click reaction of poly(HEMA-co-MMA)-alkyne and POSSAN 3 using CuBr/PMDEATA as a catalyst afforded poly(HEMA-co-MMA)-g-POSS. The structure of the organic/inorganic hybrid material was investigated by Fourier transformed infrared, 1 H-NMR, and 29 Si-NMR. The elemental mapping analysis of the hybrid using X-ray photoelectron spectroscopy and EDX also suggest the formation of poly(HEMA-co-MMA)-anchored POSS nanocomposites. The XRD spectrum of the nanocomposites gives evidence that the incorporation of POSS moiety leads to a hybrid physical structure. The morphological feature of the hybrid nanocomposites as captured by field emission scanning electron microscopy and transmission electron microscopic analyses indicate that a thick layer of polymer brushes was immobilized on the POSS cubic nanostructures. The gel permeation chromatography analysis of poly(HEMA-co-MMA) and poly(HEMA-co-MMA)-g-POSS further suggests the preparation of nanocomposites by the combination of RAFT and click chemistry. The thermogravimetric analysis revealed that the thermal property of the poly(HEMA-co-MMA) copolymer was significantly improved by the inclusion of POSS in the copolymer matrix.

Anti‐fog coatings have received significant attention because of their versatile applications to reduce light scattering during high humid conditions. Primarily, hydrophilic/superhydrophilic coatings are applied upon the transparent substrate to improve visibility at high humidity. The high solubility of the hydrophilic/superhydrophilic coatings in water is the main drawback for their long‐term operational durability. We will report for the first time the development of functional copolymers which produces water insoluble hydrophilic coating upon application on glass surfaces. Such surfaces are commonly known as “Zwitter‐Wettable” surfaces that have been developed from entirely polymeric substances using methacrylic and acrylic monomers. A series of random copolymers were synthesized using free radical polymerization of the common and commercially available monomers which were subsequently characterized using various analytical techniques, such as, GPC, 1H‐NMR, and FTIR. These newly designed copolymers contained both the hydrophobic parts made up of methyl and 2‐ethylhexyl groups, which provide good stability under high humid conditions and hydroxyl and carboxylic acid groups which will provide the required hydrophilicity or water absorption capacity. These polymeric coatings on the glass surfaces exhibit water advancing contact angles in the range of 57 ± 3° to 78 ± 3° with excellent anti‐fog property. The anti‐fog property of the polymeric films could be tuned easily by changing the ratio of hydrophobic and hydrophilic monomers.
