A Novel Inherently Flame-Retardant Composite Based on Zinc Alginate/Nano-Cu<sub>2</sub>O

A novel flame-retardant composite material based on zinc alginate (ZnAlg) and nano-cuprous oxide (Cu<sub>2</sub>O) was prepared through a simple, eco-friendly freeze-drying process and a sol-gel method. The composites were characterized and their combustion and flammability behavior were...
