Study of the mechanical properties of two organic-inorganic hybrid systems: GPTMS/colloidal silica and GPTMS/TEOS

► We study the mechanical properties of: GPTMS/TEOS and GPTMS/colloidal silica systems. ► Results show an increase in mechanical properties for both systems. ► The GPTMS/TEOS is more scratch resistant than the GPTMS/colloidal silica one. ► The importance of silica filler morphology in mechanical properties of hybrid materials.
