Bio-based smart coating combines fire protection, early warning and upcyclability

Researchers have developed a multifunctional fire-protective coating that not only shields materials from extreme heat but also provides an early warning of fire and can be recycled into new flame-retardant materials at the end of its life. The work, published in Polymer Degradation and Stability, demonstrates a strategy for combining fire safety, sustainability and circularity within a single material system.
