Abstract

Carbonized cotton fabric possesses lightweight softness, stable chemical structure and can be used as wearable electronic skin. However, conventional carbonization method relies on high temperature, oxygen-free or inert gas atmosphere with long time consumption. In this study, a hybrid intumescent flame retardant (IFR) coating was introduced on the surface of cotton fabric. When they were placed directly into the heated muffle furnace at air atmosphere, the IFR coating would quickly react with the cotton fiber to form char residue and release non-inflammable gases, providing an inert atmosphere microenvironment for the pyrolysis and carbonization of cotton fabric substrate. The influence factors of temperature and carbonization time were studied comprehensively. Especially, carbonizing for only 15 min at 900 °C shows a value of 26.33 dB. Besides, such fabrics perform the ability for photo-thermal conversion and fire resistance performance. This simple and feasible carbonization strategy holds great promise for large-scale production of flexible conductive fabrics.

期刊介绍： Composites Part A: Applied Science and Manufacturing is a comprehensive journal that publishes original research papers, review articles, case studies, short communications, and letters covering various aspects of composite materials science and technology. This includes fibrous and particulate reinforcements in polymeric, metallic, and ceramic matrices, as well as 'natural' composites like wood and biological materials. The journal addresses topics such as properties, design, and manufacture of reinforcing fibers and particles, novel architectures and concepts, multifunctional composites, advancements in fabrication and processing, manufacturing science, process modeling, experimental mechanics, microstructural characterization, interfaces, prediction and measurement of mechanical, physical, and chemical behavior, and performance in service. Additionally, articles on economic and commercial aspects, design, and case studies are welcomed. All submissions undergo rigorous peer review to ensure they contribute significantly and innovatively, maintaining high standards for content and presentation. The editorial team aims to expedite the review process for prompt publication.
