The Role of γ -Aminopropyltriethoxysilane (γ -APS) on Thermal Stability of TEOS-PDMS Ormosils
The degradation process of TEOS-PDMS Ormosils containing different amounts of γ -APS has been studied by means of DTA, TG, FTIR and 29Si-NMR measurements. It has been found that the amount of γ -APS improved the ...

A FT-IR Study of the Synthesis of Boron Ormosils by Means of the Sol-Gel Process
Borosilicon ormosil materials can be prepared by using the sol-gel method. The precursors used for the synthesis were TEOS (tetraethylorthosilicate), TEB (triethylborate) and PDMS (silanol terminated polydimet...
