Flame-retardant coatings for clothing and foam in furniture could soon be made of environmentally benign substances such as clay and polysaccharides, according to work presented at the American Chemical Society national meeting in Denver last week. The new layered films might answer the call for safer alternatives to commonly used halogenated compounds, such as polybrominated diphenyl ethers, that are being phased out because of toxicity concerns.

Using layer-by-layer assembly, a process in which a substrate . . .
