Special Issue Information

Dear Colleagues,

Modern life without organic polymers is probably unimaginable. Polymers are vital ingredients of different products we use daily. Polymers are also among the most important ingredients of the organic coatings used for the protection and longevity of various metallic structures across the globe. Organic coatings, applied heavily to protect metallic structures of immense commercial importance (e.g., automobiles, ships, chemical manufacturing plants, wind turbines, oil rigs, etc.), use a variety of polymers as binders, co-binders, rheology modifiers, etc., in a sophisticated balance with the other ingredients (e.g., extenders/fillers, pigments, etc.) in the coatings to perform their desired function in real-life contexts. Therefore, it is important to control the molecular structure and properties of polymers intended for use in coatings.

Although the developments in science and technology have enabled the production of polymers with precisely controlled molecular structures, the industry is still in need of advanced polymeric materials serving multiple and predictable functions with the lowest possible material and monetary cost. The current era of renewable and recyclable polymers has increased the demand for such advanced polymers. Therefore, this Special Issue is dedicated to the publication of research articles disseminating the synthesis, properties and applications of advanced polymeric materials and coatings.

Abstract
A nanoparticle-anchored three-dimensional microsphere flower-structured layered double hydroxide (LDH) material with Fe3O4 particles was successfully prepared using simple hydrothermal and hot solvent methods. Micro-nanostructured Fe3O4@LDHs (SLF) composites balance microwave absorption, corrosion protection, and UV aging resistance. [...] Read more.
A nanoparticle-anchored three-dimensional microsphere flower-structured layered double hydroxide (LDH) material with Fe3O4 particles was successfully prepared using simple hydrothermal and hot solvent methods. Micro-nanostructured Fe3O4@LDHs (SLF) composites balance microwave absorption, corrosion protection, and UV aging resistance. The minimum reflection loss value of SLF is −35.75 dB at 14.16 GHz, when the absorber thickness is 8 mm, and the absorption bandwidth at this frequency is up to 2.56 GHz for RL values less than −10 dB, while the LL is only 1 GHz. The SLF /EP coating has not only excellent microwave absorption performance but also excellent corrosion and UV aging resistance performance. The coating still has some anti-corrosion effect after 10 d of immersion. This work is intended as a reference for the development of new coatings with excellent microwave absorption properties as well as corrosion and UV aging resistance for wind turbine tower barrels (seaside wind power generation equipment) surfaces.

Abstract
This study explores the synthesis and evaluation of UV-curable urethane (meth)acrylates (UA) incorporating a Diels–Alder adduct (HODA), diisocyanate, poly(ethylene glycol), and hydroxy (meth)acrylate.

This study explores the synthesis and evaluation of UV-curable urethane (meth)acrylates (UA) incorporating a Diels–Alder adduct (HODA), diisocyanate, poly(ethylene glycol), and hydroxy (meth)acrylate. Six UAs, distinguished by the soft segment of polymer chains, underwent comprehensive characterization using FTIR and NMR spectroscopy. Real-time monitoring of the UV-curing process and analysis of self-healing properties were performed. The research investigates the influence of various molecular weights of PEGs on the self-healing process, revealing dependencies on photopolymerization kinetics, microstructure, thermal properties, and thermoreversibility of urethane (meth)acrylates. This work provides valuable insights into the development of UV-curable coatings with tailored properties for potential applications in advanced materials. Full article

Phthalocyanine pigments have many problems in waterborne coating applications because of their low polarity, poor dispersion in water, and easy agglomeration properties. In order to solve these problems, the phthalocyanine pigments were encapsulated with a copolymer of methyl methacrylate (MMA) and butyl acrylate (BA) by a mini-emulsion polymerization method. The pigments are effectively dispersed in water and have good compatibility with the resin. Concerning the bacterial reproduction and growth problem for the waterborne system, the resin-encapsulated phthalocyanine pigments were further grafted with antibacterial polymer poly(N-(2-hydroxyethyl) acrylamide) (PHEAA) on its surface using the photoemulsion polymerization technique. Comprehensive properties, including centrifugal stability and chromaticity change, were studied. The polymer encapsulation improved the centrifugal stability of the pigment. The thermogravimetric results showed that the residual mass of C.I. Pigment Green 7 (52.30%) was higher than that of C.I. Pigment Blue 15:3 (30.06%), and the sublimation fastness of PG7 was higher. The TEM results revealed that the shape of the PG7 after encapsulation and grafting was more regular than that of PB15:3. The L* of the pigment decreased after encapsulation but then increased after further grafting. The phthalocyanine pigment composite latex had good antibacterial properties after the grafting of PHEAA. Full article

Electronic skin (E-skin) is increasingly utilized in modern society, yet current E-skin technology suffers from issues, such as opacity, hardness, and fragility. To address these challenges, a novel E-skin was developed using polyurethane (PU) as the matrix material and silver nanowires (AgNWs) as the sensing material. By leveraging the small degree of microphase separation and lack of crystallization in the PU, combined with the appropriate length–diameter ratio of the AgNWs, the resulting E-skin exhibited a visible light transmittance of 75%. The E-skin also showed excellent self-healing properties (83.63% efficiency in the third repair) and mechanical properties (with almost no degradation after 60 tensile cycles) due to the reversible dynamic cross-linking network within the PU. The synergistic effect of PU and AgNWs resulted in exceptional sensing performance for the E-skin, with a gauge factor of 46 (when ε = 10%). Moreover, the E-skin demonstrated signal stability during human joint motion monitoring and successfully identified different movement states, highlighting its potential for diverse applications. This research presents a simple yet effective approach for producing transparent, durable, and stable E-skin. Full article

In order to meet the anticorrosion and wear resistance requirements of petroleum pipelines, we selected a polymer (FC) containing difunctional hydroxyl propyl acrylate (HPA) and perfluoroalkyl ethyl acrylate (TEAc-N) free radical polymerization to prepare hydrophobic fluorocarbon chain oil and a hydroxyl special functional group. Combined with tetrafluororesin (F4), the hydrophobic, wear-resistant and corrosion-resistant properties of epoxy coating were improved. The optimum synthesis ratio of TEAc-N:HPA was 9:1, and the FC polymer with the best hydrophobicity was prepared. The hydrophobic angle of the coating was 100.3% higher than that of pure Q235 section steel. By adding 5 wt.% of FC to epoxy resin (EP), the hydrophobicity increased by 65.4% and oleophobicity increased by 32.1% compared with pure EP. The coefficient of friction was reduced by 73.8%. EIS test results showed that the impedance modulus in the low frequency region (|Z|0.01 Hz) was two orders of magnitude higher than that of the pure epoxy coating. The composite coating has sufficient utility to meet the wear, heat and corrosion resistance requirements for oil pipeline transportation. Full article
