Four kinds of liquid‐like polyhedral oligomeric silsesquioxanes derivatives (liquid‐Ds) were fabricated and characterized by FTIR, XPS, TGA, and Rheometer. The liquid‐Ds/epoxy nanocomposites were prepared and their thermal resistance properties were tested by TGA. As a result, the thermal resistances properties were improved sharply and influenced by particle sizes, flow abilities, and bonding types of liquid‐Ds. The glass transition temperature improved via adding liquid‐Ds. The increase of crosslinking density was thought as an important factor to these improvements, which was studied by FTIR spectra and gel content of curved nanocomposites. POLYM.
