英文摘要：

In this paper, the recent research development of four kinds of flame-retardants was summarized i. e., inorganic nanoparticulate, nanolayered, fibrous, and nanocatalysed flameretardants. Their effects on thermal, mechanical properties, and flame retardancy of materials were discussed. At last, the existing problems and the developing direction of inorganic flameretardants were pointed out.
