Synthesis and thermal stability of cross-linked carbazole-substituted Poly(dimethylsiloxane) for LED encapsulation
A series of carbazole substituted poly(dimethylsiloxane) (PDMS) was synthesized by hydrosilylation reaction of 9-vinyl carbazole into PDMS structure. It was then cross-linked with vinyl trimethoxysilane by condensation reaction. The fabricated product display increasing in refractive index with i...

| Summary: | A series of carbazole substituted poly(dimethylsiloxane) (PDMS) was synthesized by
hydrosilylation reaction of 9-vinyl carbazole into PDMS structure. It was then cross-linked with
vinyl trimethoxysilane by condensation reaction. The fabricated product display increasing in
refractive index with increasing carbazole content. The higher carbazole content also produce high
thermal stability which is suitable for electronic device encapsulation applications. The
modification also increase Tg of the polymers displayed by differential scanning calorimetry
analysis. This behavior owe much to the carbazole moeity when it was successfully incorporated
into PDMS chain. |
