Abstract

Chemical warfare agents (CWAs) could penetrate into the interior of some items, which would cause the difficulty of decontamination and pose a significant security threat to personnel due to the desorption of CWAs. In this study, fluoro-silicon-epoxy acrylate ternary prepolymer was firstly prepared, which contained fluoroalkane, epoxy and siloxane groups in its side chains. Then, fluorinated silione-modified epoxy acrylate coatings were prepared using 4,4′-diaminodicyclohexylmethane (DDCM) and organofluorosiloxane as mixed curing agents, which had excellent protective properties against 2-chloroethylethyl thioether (CEES) and dimethyl methylphosphonate (DMMP), simulants of mustard and nerve agents. Compared to the coating prepared using DDCM, the coatings prepared with mixed curing agents possessed significantly enhanced amphiphobic properties while maintaining high resistance to CWAs simulants. By controlling the length of the fluorine-containing segment, diverse rough structures could be formed on the surface of the coating. The crosslinking density, relative fractional free volume, low surface energy materials, and rough structures were key factors for achieving coatings with good anti-penetration and amphiphobic properties against simulants. The Barrier rate of the coating against DMMP and CEES could reach 99.96% and 100%, respectively. Furthermore, contact angles of DMMP, CEES, and water on the coating could reach 120°, 109°and 148°, respectively.

期刊介绍： European Polymer Journal is dedicated to publishing work on fundamental and applied polymer chemistry and macromolecular materials. The journal covers all aspects of polymer synthesis, including polymerization mechanisms and chemical functional transformations, with a focus on novel polymers and the relationships between molecular structure and polymer properties. In addition, we welcome submissions on bio-based or renewable polymers, stimuli-responsive systems and polymer bio-hybrids. European Polymer Journal also publishes research on the biomedical application of polymers, including drug delivery and regenerative medicine. The main scope is covered but not limited to the following core research areas: Polymer synthesis and functionalization • Novel synthetic routes for polymerization, functional modification, controlled/living polymerization and precision polymers. Stimuli-responsive polymers • Including shape memory and self-healing polymers. Supramolecular polymers and self-assembly • Molecular recognition and higher order polymer structures. Renewable and sustainable polymers • Bio-based, biodegradable and anti-microbial polymers and polymeric bio-nanocomposites. Polymers at interfaces and surfaces • Chemistry and engineering of surfaces with biological relevance, including patterning, antifouling polymers and polymers for membrane applications. Biomedical applications and nanomedicine • Polymers for regenerative medicine, drug delivery molecular release and gene therapy The scope of European Polymer Journal no longer includes Polymer Physics.
