Abstract

The work aims to explore the advantages and applications of hydrogels as fire extinguishers and fire suppressants. It summarized their mechanisms, material sources, preparation methods, and applications based on literature research, while addressing challenges and prospects. In conclusion, hydrogels exhibit significant fire prevention potential due to multiple flame-retardant mechanisms (such as heat absorption and cooling, covering and blocking and free radical inhibition) and green sustainability. With the innovative breakthroughs in materials science and technology, hydrogels are expected to develop into novel and eco-friendly fire-fighting materials that integrate functions such as green shock-absorbing packaging, efficient fire extinguishing, and environmental friendliness, providing more reliable fire safety guarantees for multiple fields including industry, forestry, and transportation.
