Using a 60Co gamma source polydimethylsiloxane-based materials have been prepared by
gamma-irradiation of a mixture of polydimethylsiloxane, PDMS, silanol-terminated and the
tetraethylortosilicate, TEOS, with no other chemicals. Samples were prepared with varying
TEOS concentrations. The obtained materials are monolithic, flexible and transparent. X-ray
measurements have shown them to be amorphous. The thermal behaviour has also been
investigated by using differential scanning calorimetry and thermal gravimetric analysis. The …
