Abstract
This paper reports our investigation regarding the thermal properties of new polymer-silica hybrid materials obtained by radiation grafting. The polymer poly(dimethylsiloxane),bis(3-aminopropyl)terminated is γ-grafted on a silica gel surface. The thermal behavior of γ-grafted hybrid materials reveals remarkable differences compared to the thermal behavior of phys. adsorbed polymers. These differences allow us to assess the ability of γ-rays to produce a polymer chem. bonded on a silica surface. The chem. bonds formed by irradn. give to the polymer a high conformational stability confirmed by DTA anal.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
