“…[11][12][13][14][15] Organic coatings have also attracted considerable attention owing to versatility, light-weight and easy process. 21,22 Such materials have been widely investigated as anchoring group to multi-functionalize surface of base materials, 23-31 adhesives, 32-37 anti-bacterial, [38][39][40] and some biological applications. 18 It is noteworthy to mention that such organic coating exhibit high protection efficiency even at below sub-micron thickness.…”

The anticorrosion ability of ultrathin coatings with bio-inspired organic polymers is demonstrated. We prepared a series of catechol-containing poly(alkyl methacrylate)s by free radical polymerization. These copolymers were spin-coated on various corrosion susceptible metal/alloy substrates of magnesium, aluminum, copper and iron without any harsh pretreatment. Several key factors like molecular structure, composition ratio and processing conditions were wisely tailored to afford a transparent, firm and submicron polymer coating on those substrates. Corrosion resistance of the polymer-coated substrates was thoroughly investigated by immersion tests in salt-water and acidic solutions, polarization tests, and visual inspection. Formation of an anomalous dense layer of ca. 5 nm thickness adjacent to the metal surface and a remarkable effect of thermal treatment were clearly observed by neutron reflectivity measurements, leading to a highly protective ability against foreign molecules e.g. water or corrosive ions. A key molecular design for anticorrosive polymer coating was revealed to be a combination of strong and versatile binding ability of catechol units and defect free polymer layers formed on the metal substrates in the presence of hydrophobic alkyl chains.

“…N ‐(3,4‐dihydroxyphenethyl)methacrylamide (DMA) was prepared from dopamine hydrochloride and methacrylate anhydride according to the literature . DMA was used as a monomer having a catechol group . The amphiphilic copolymer (polymer 1, Scheme ), which contained the catechol group, was synthesized from DMA (2.78 × 10 –3 mol) and N ‐dodecylacrylamide (DAA, 22.4 × 10 –3 mol) by free‐radical polymerization (for details, see Supporting Information).…”

High-performance catalysts and photovoltaics are required for building an environmentally sustainable society. Because catalytic and photovoltaic reactions occur at the interfaces between reactants and surfaces, the chemical, physical, and structural properties of interfaces have been the focus of much research. To improve the performance of these materials further, inorganic porous materials with hierarchic porous architectures have been fabricated. The breath figure technique allows preparing porous films by using water droplets as templates. In this study, a valuable preparation method for hierarchic porous inorganic materials is shown. Hierarchic porous materials are prepared from surface-coated inorganic nanoparticles with amphiphilic copolymers having catechol moieties followed by sintering. Micron-scale pores are prepared by using water droplets as templates, and nanoscale pores are formed between the nanoparticles. The fabrication method allows the preparation of hierarchic porous films from inorganic nanoparticles of various shapes and materials.

“…[18] A SIP is commonly performed using initiating moieties already attached to the substrate's surface. [19] These polymerization initiators are initially anchored to the nanofiller surface, either chemically or physically, or by forming a covalent linkage and followed by in situ activation in the presence of monomers under polymerization conditions. [20] The main advantage of SIP procedures is derived from growing the polymer chains after surface initiation; hence, the internal distance between the clay layers is gradually increased resulting in a well-dispersed as well as a highly ordered structure in the final product.…”

The surface of Cloisite 30 B clay was treated with bromopropionyl bromide to form the clay Br-ended initiator needed for surface-initiated atom transfer radical polymerization (SI-ATRP). Several homo-and co-(SI-ATRP) polymerizations were conducted on the cured surface of the Cloisite 30 B clay using vinyl monomers, such as methyl methacrylate, styrene (St), and 2-(dimethylaminoethyl) methacrylate, along with the ligands 2,2′-bipyridine (bpy) and 1,1,4,7,10,10-hexamethyltriethylene tetraamine, and CuBr, as a catalyst. These grafted polymer-clay nanocomposites were characterized by X-ray diffraction, Thermal gravimetric analysis, differential scanning calorimetry, and Transmission electron microscopy. Most of the prepared nanocomposites displayed semi-exfoliated to exfoliated structures.
