연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Abstract ▼ AI-Helper 아이콘AI-Helper

A mixture of polysiloxane (PSO) and polysilazane (PSZ) was used to prepare a crosslinked organosilicon material for use as an LED encapsulant. The crosslinking was conducted by using two different chemistries: platinum-catalyzed hydrosilylation and peroxide-initiated radical reaction. Successful cro...

제안 방법

  • Crosslinking of Resin: A mixture of PSO and PSZ in predetermined ratios and crosslinking agent (0.03 % (w/w) Pt(dvs) or 0.01 % (w/w) CPO) was prepared. The mixture was poured into a pre-formed mold, composed of two slide glasses which are separated by 1 mm.
  • To be used as an encapsulant in LED, the silicon-based materials should be properly crosslinked. In this study, two different crosslinking mechanisms were applied, hydrosilylation between hydrosilanes and vinyl groups, and radical crosslinking. PSZ can be co-crosslinked with siloxane resins through either Pt catalyzed hydrosilylation [19] or radical crosslinking reactions.
  • Molecular weight and its distribution were obtained using gel permeation chromatography (GPC, Waters) with a series of two/three PLGEL MIXED-C columns (5 μm, Agilent).

대상 데이터

  • Poly(vinyl silazane) (PSZ, CerasetTM VL20) was obtained from Kion Corporation, USA. Barium hydroxide (Ba(OH)2), platinum(0)-1,3-divinyl-1,1,3,3-tetramethyldisiloxane complex (Pt(dvs), in xylene, Pt ~2%), and dicumyl peroxide (CPO) were purchased from Aldrich. All other chemicals were obtained from commercial suppliers as first grade and used without further purification.
  • In this study, polysiloxane and polysilazane mixture resin were used as LED encapsulant materials. The mixed resin showed high transparency because of the excellent miscibility between the component polymers.
  • Poly(vinyl silazane) (PSZ, CerasetTM VL20) was obtained from Kion Corporation, USA. Barium hydroxide (Ba(OH)2), platinum(0)-1,3-divinyl-1,1,3,3-tetramethyldisiloxane complex (Pt(dvs), in xylene, Pt ~2%), and dicumyl peroxide (CPO) were purchased from Aldrich.
