Special Issue Information

Dear Colleagues,

Polymer coatings play a pivotal role in modern materials science and engineering, serving as functional interfacial layers that provide protection, enable advanced functionalities, and enhance the performance and durability of underlying substrates. With rapid progress in polymer chemistry, processing technologies, and characterization methods, polymer coatings have evolved far beyond conventional protective layers and have become indispensable components in a wide range of advanced systems, including electronics, biomedical engineering, energy technologies, corrosion protection, and smart materials.

This Special Issue of Coatings, entitled “Polymer Coatings: Fundamentals and Applications”, aims to systematically showcase the latest advances in both fundamental mechanistic studies and engineering applications of polymer coatings. Particular emphasis is placed on elucidating structure–property–function relationships, interfacial physical and chemical behaviors, and the intrinsic correlations between processing strategies and in-service performance, which collectively govern the reliability, stability, and multifunctional integration of coating systems. Contributions that effectively bridge fundamental insights with application-driven requirements are especially encouraged.

The scope of this Special Issue includes, but is not limited to, polymer coatings for electronic packaging, bioelectronics, biomedical engineering, and tissue engineering, where electrical functionality, biocompatibility, mechanical compliance, and long-term interfacial stability are of critical importance. Functional polymer coatings for energy-related applications, such as energy storage, energy conversion, and electrochemical systems, are also within scope, with particular interest in interfacial regulation, performance optimization, and durability enhancement. In addition, works on polymer coatings designed for corrosion protection and harsh or extreme environments are strongly encouraged, with emphasis on long-term stability, adhesion strength, and environmental resistance. Advances in micro- and nano-scale coating technologies, including micro-/nano-welding, joining, and interfacial engineering strategies, as well as polymer coatings enabling electrochromic, optoelectronic, and multi-physical coupled functionalities, are likewise welcomed.

Original research articles, short communications, and comprehensive review papers are invited. By bringing together contributions from diverse application domains, this Special Issue seeks to highlight emerging trends, unresolved challenges, and future opportunities in polymer coatings, while fostering interdisciplinary exchange among researchers in coating science, engineering, and applications.

During service in engineering fields, the performance of carbon black (CB)/silica-filled rubber suffers degradation because of the influence of aging. In the process of reproducing the mechanical behavior of CB/silica-filled rubber, many constitutive models have been proposed. However, the model selection strategy taking the aging effect into consideration is still unclear, especially the classical model selection strategy. In this work, the effects of thermo-oxidative and ultraviolet aging on the nonlinear viscoelasticity of CB/silica -filled rubber were investigated using dynamic mechanical analysis tests. It was found that aging conditions had a great effect on the nonlinear viscoelasticity of CB/silica -filled rubber. Meanwhile, the degradation mechanisms were discussed on the basis of the existing works. To accurately reproduce the nonlinear viscoelasticity degradation, classical models, such as the Kraus model and Maier–Göritz model, were used to describe the experimental data. In the reproducing process, fitting correlation coefficients and root mean square error were used to verify the reliability of classical models. Comparingsimulation results and experimental ones, it was found that the Maier–Göritz model was more reliable under all aging conditions. This work will contribute to a model selection strategy and a deeper understanding of the degradation mechanism. Full article

Biofouling has a detrimental effect on marine infrastructure and poses a severe challenge to the global marine industry. Therefore, developing efficient and environmentally friendly anti-fouling coatings to protect those facilities has become extremely necessary nowadays. To address marine biofouling, a series of photocurable degradable waterborne boron-containing polyurethane acrylate (WPU-PTPBx) anti-fouling coatings were prepared by grafting pyridine-triphenylborane (PTPB) onto polyurethane side chains and UV curing. FTIR and 1H NMR confirmed the successful grafting of PTPB. The WPU-PTPBx aqueous dispersions had a particle size of 30~75 nm with excellent thermal storage stability. DSC and XRD characterizations revealed the amorphous structure of the coatings, which favored biodegradation. All coatings exhibited adhesion strength over 2 MPa, meeting marine application requirements. Antibacterial and anti-algal tests showed that PTPB content positively correlated with anti-fouling performance: the coating achieved a 99.66% inhibition rate against Escherichia coli and reduced the adhesion density of Nitzschia closterium to only 36.9 cells/mm2. With favorable degradability and outstanding anti-fouling performance, WPU-PTPBx coatings are promising green anti-fouling materials for marine applications. Full article
