“…In this regard, polymer grafting on inorganic, metal or carbon‐based surfaces, known as polymer brushes, is of particular importance in many fields of application . Polymers tethered to inorganic surfaces like SiO 2 , Fe 3 O 4 , ZnO, Au or alumina have attracted extensive research interest due to the ability to modify the surface characteristics and have applications in basic and applied interfacial studies. One of the most promising support matrices, for incorporation of polymer species, is superparamagnetic iron oxide nanoparticles with high surface area, which are easily obtained from commercially available materials such as FeCl 3 ⋅6H 2 O and FeCl 2 ⋅4H 2 O in water .…”

Funding information Semnan University Research CouncilThe purpose of this work was to synthesize and characterize a new magnetic polymer nanosphere-supported palladium(II) acetate catalyst for reactions requiring harsh conditions. In this regard, an air-stable, moisture-stable and highly efficient heterogenized palladium was synthesized by the coordination of palladium(II) acetate with poly(2-acrylamido-2-methyl-1-propanesulfonic acid)-grafted modified magnetic nanoparticles with a core-shell structure.The structure of the newly developed catalyst was characterized using various techniques. The catalytic activity of the resultant nano-organometallic catalyst was evaluated in Mizoroki-Heck and Suzuki-Miyaura reactions to afford the corresponding coupling products in good to excellent yields. High selectivity as well as outstanding turnover number (14 143, 4900) and turnover frequency (28 296, 7424) values were recorded for the catalyst in Suzuki-Miyaura and Mizoroki-Heck reactions, respectively. Magnetic separation and recycling of the catalyst for at least six runs became possible without any significant loss of efficiency or any detectable palladium leaching.

Effect of the Composition of Copolymers Based on Glycidyl Methacrylate and Fluoroalkyl Methacrylates on the Free Energy and Lyophilic Properties of the Modified Surface

et al. 2022

This study proposes to use reactive copolymers based on glycidyl methacrylate and fluoroalkyl methacrylates with a low fluorine content in the monomer unit as agents to reduce the surface free energy (SFE). This work reveals the effect of the structure and composition of copolymers on the SFE and water-repellent properties of these coatings. On a smooth surface, coatings based on copolymers of glycidyl methacrylate and fluoroalkyl methacrylates with fluorine atoms in the monomer unit ranging from three to seven are characterized by SFE values in the range from 25 to 13 mN/m, which is comparable to the values for polyhedral oligomeric silsesquioxanes and perfluoroalkyl acrylates. On textured aluminum surfaces, the obtained coatings provide time-stable superhydrophobic properties with contact angles up to 170° and sliding angles up to 2°. The possibility of using copolymers based on glycidyl methacrylate and fluoroalkyl methacrylates for the creation of self-cleaning polymer coatings is shown.

“…Previously we demonstrated pathways for modifi cation of the aluminum surface with grafted polymers for controlling its lyophilic properties [7][8][9]. However, the problem of preparing stable adaptive polymeric coatings [10][11][12] ensuring control of the surface properties at repeated cyclic changes of the external conditions without degradation of functional properties of the polymer remains topical.…”

A block copolymer based on N-isopropylacrylamide and glycidyl methacrylate was synthesized by atom transfer radical polymerization with the aim of modifi cation of the aluminum surface by the "grafting to" method. The copolymer structure was proved by elemental analysis, gel permeation chromatography, and differential scanning calorimetry. The grafting of the block copolymer to the aluminum surface allows control of its wettability at repeated temperature changes.
