英文摘要：

Polyhedral oligomeric silsesquioxane （POSS） polymer nanocomposites have received intensive attentions due to its cage-like structure. Recent investigations on POSS polymer nanocomposites were reviewed. The definition, classification and synthetical methods of POSS monomers and its polymer nanocomposites were documented and discussed in details. The applications for these polymer nanocomposites were introduced and forecasted. Additionally, the developing trends of POSS polymer nanocomposites in the future were also discussed.
