Abstract
Abstract The output of bio-based polyvinyl alcohol (PVA) has been growing rapidly with a substantial increase of developments both in academic and industrial research areas in the past decade, which is due to its water solubility, plasticity, and degradability. However, PVA is highly flammable with a limiting oxygen index of only 19% owning to its inherent macromolecular structure composed of carbon, hydrogen, and oxygen atoms. The demand for flame retardancy of PVA has been increased rapidly and is generally satisfied by introducing flame retardants via chemical grafting, physical blending, and coating. This review summarizes the flame retardants applied in PVA and their influence on the flammability and mechanical properties of PVA materials. The type of flame retardant additives and their application technologies for various PVA products are presented in terms of various PVA products, such as films, aerogel, fibers, foams, and bulk composites. The films dominate the whole research of flame retardant PVA materials owing to their widespread application. The fire performance and flame retardant mechanism are compared and discussed. Additionally, PVA acted as an assistant agent in some polymeric flame-retardant formulations is also discussed and reviewed.
期刊介绍：
Polymer Reviews is a reputable publication that focuses on timely issues within the field of macromolecular science and engineering. The journal features high-quality reviews that have been specifically curated by experts in the field. Topics of particular importance include biomedical applications, organic electronics and photonics, nanostructures, micro- and nano-fabrication, biological molecules (such as DNA, proteins, and carbohydrates), polymers for renewable energy and environmental applications, and interdisciplinary intersections involving polymers.
The articles in Polymer Reviews fall into two main categories. Some articles offer comprehensive and expansive overviews of a particular subject, while others zero in on the author's own research and situate it within the broader scientific landscape. In both types of articles, the aim is to provide readers with valuable insights and advancements in the field of macromolecular science and engineering.
