Abstract: | Starting from the functional cyclotriphosphazene, polysiloxane and nano-SiO2 precursors, three new hybrid nanocomposites with reinforced mechanical properties were prepared. Young’s modulus values for all the composite samples are similar in the range of 7–11 MPa, stress at fracture increases with the nano-SiO2 content increase in the material and reaches a maximum value of 36 MPa for the composite with 20% nano-SiO2. The nanocomposites investigated are elastic and demonstrate the ability to be deformed without failure up to 54% strain. |
