- Fumed nanosilicas with different degree of silanization were used to obtain nanosilica‐polyurethane (TPU) composites to modify their rheological and mechanical properties. The higher the silanol content of the nanosilica, the higher the storage modulus and the thermal stability of the silica‐TPU composite. DMTA experiments confirmed that the TPU‐silica interactions increased by increasing the silanol content of the nanosilica.
