Special Issue Information

Dear Colleagues,

Polymer-based coatings fulfil a vital role in our daily lives. They can enhance the water- and grease-resistance of various materials, provide corrosion resistance, protect substrates against physical wearing, and enhance the appearance of materials. Polymer-based coatings can provide a highly effective and facile approach to impart unique properties to a material (such as wood, paper, metals, or other surfaces) that it would not otherwise possess. The theme of this Special Issue is focused on polymer-based coatings, such as those that can be used to improve the properties of a given substrate, provide a substrate with new properties, or help protect a substrate against damage or contamination. We welcome submissions focused on various aspects of polymer coatings, such as the development of new polymer-based coatings, the development of new strategies to apply coatings onto substrates, or other aspects of polymer coating research. Research papers, communications, and review articles are welcomed as contributions to this Special Issue. It is hoped that this Special Issue will provide valuable insights into this field of research.

With the increasing urgency of petroleum resource scarcity and environmental challenges, the development of degradable bio-based flame retardants has become crucial for enhancing the fire safety of organic materials. In this work, a phosphorus-containing chitosan derivative (CS-PPOA) was synthesized via a one-step protonation reaction between chitosan (CS) and phenylphosphinic acid (PPOA) under mild conditions. The resulting multifunctional flame-retardant coating was applied to polyester (PET) fabrics. Comprehensive characterization using FT-IR, XPS, and NMR confirmed the successful protonation of chitosan amino groups through electrostatic interactions, forming a stable ionic complex. The CS-PPOA solution exhibited excellent rheological properties and film-forming ability, producing films with over 80% optical transmittance and flexibility. Thermogravimetric analysis (TGA) revealed that CS-PPOA achieved char residue yields of 76.8% and 40.2% under nitrogen and air atmospheres, respectively, significantly surpassing those of acetic acid-protonated chitosan (CS-HAc). The limiting oxygen index (LOI) of CS-PPOA increased to 48.3%, and vertical burning tests demonstrated rapid self-extinguishing behavior. When applied to PET fabrics at a 15% loading, the LOI value improved from 20.3% (untreated fabric) to 27.8%, forming a dense char layer during combustion while completely suppressing melt dripping. Additionally, the coated fabric exhibited broad-spectrum antibacterial activity, achieving a 99.99% inhibition rate against Escherichia coli and Staphylococcus aureus. This study provides a novel strategy for the green and efficient preparation of multifunctional bio-based flame-retardant coatings. Full article
