Water-resistant and flame-retardant waterborne polyurethane coating based on hydrophobic SiO2 and microcapsule perfluorohexanone: With automated intelligent fire early warning and fire protection
This is the first report of a Waterborne Polyurethane Coating integrating microcapsule perfluorohexanone (1230) for autonomous fire suppression. The coating features a unique thermochromic system that exhibits visible color transition at 80 °C, providing real-time thermal hazard alerts, while 1230 automatically ruptures at 125 °C to release flame-suppressing agents. Hydrophobic SiO2 nanoparticles (10 wt%) enhance surface roughness (a 32.1 % increase inwater contact angle) and catalyze condensed-phase char formation, synergizing with the gas-phase radical scavenging from 1230 to achieve a 15.7 % reduction in peak heat release rate. Comprehensive characterization, including TG, SEM, FT-IR, XPS, and XRD confirms uniform filler dispersion and chemical stability, accelerated aging tests demonstrate sustained performance under 85 % RH/55 °C and salt spray conditions, while TG-IR analysis reveals suppressed pyrolysis products, underscoring the coating's eco-friendly profile. This work provides a scalable strategy for designing multifunctional coatings, ridging gaps in fire safety, environmental durability, and intelligent fire early warning.
期刊介绍:
The aim of this international journal is to analyse and publicise the progress and current state of knowledge in the field of organic coatings and related materials. The Editors and the Editorial Board members will solicit both review and research papers from academic and industrial scientists who are actively engaged in research and development or, in the case of review papers, have extensive experience in the subject to be reviewed. Unsolicited manuscripts will be accepted if they meet the journal''s requirements. The journal publishes papers dealing with such subjects as:
• Chemical, physical and technological properties of organic coatings and related materials
• Problems and methods of preparation, manufacture and application of these materials
• Performance, testing and analysis.
