| Abstract: | A novel high refractive index and high transparent silicone resin-type material for the packaging of light emitting diode(LED) was introduced.The methylphenyl vinyl silicone resin was synthesized by cohydrolysis of MePhSiCl 2 with Me 2SiCl 2,MeViSiCl 2 and PhSiCl 3,then by co-condensation polymerization catalyzed by KOH and end-capped with Me 3SiCl.Then the silicone material for LED packaging was prepared with the produced methylphenyl vinyl silicone resin,methylphenyl hydrosilicone oil and Karstedt’s catalyst.The methylphenyl vinyl silicone resins were characterized by FTIR and 1H NMR.The silicone resins prepared with very high transmittance at range of 400-800 nm after cured.The LED packaged with the silicone resin-type materials exhibited higher luminous flux,higher light efficiency,narrower color-rendering index and higher color-temperature consistency. |
