Characteristic Features

Polymer-derived SiCN glasses with tailored polymer architectures were characterized by TEM and EF-SAED upon pyrolysis at 1000 °C and subsequent annealing. Main emphasis of this work was to verify as to whether the intrinsic amorphous structure of polymer-derived bulk materials exhibits different structural features upon pyrolysis, depending on the functionalities of the pre-ceramic polymer, and whether such characteristic features are maintained upon high-temperature anneal.
