전자전이 고분자 착체를 이용한 광기록 매체
Optical Recording Media via Charge Transfer Polymer Complex
초록
금속 대신에 electron donor 로서 polymer (polycation) 를 사용한 polymer - TCNQ (tetracyanoquinodimethane)전하이동 착체를 합성하고 광기록 매체로의 적용 여부를 타진하였다. Polymer의 main chain에 cation구조를 가지는 2,6-Ionene-TCNQ와 side chain에 cation구조를 가지는 poly(1-butyl-4-vinylpyridinium-TCNQ), poly(styrene co 1-butyl-2-Vinylpyridinium- TCNQ)를 합성하였다. 이 중 side chain형탱의 polymer들이 용해성 및 코팅성이 우수하여 이들을 기록층으로 polycarbonate 기판 위에 코팅하여 막면 입사형으로 830um에서 광기록 평가 실험을 행하였다. 기록 속도 1.2 m/s, 기록 power 8.9 mW에서 최고 40dB의 CNR이 관찰되었다.
Polymers(polycations) instead of metals were used as the electron donor, and polymer-TCNQ
(tetracyanoquinodimethane) charge transfer complexes were synthesized. These charge transfer complexes were tested whether they can be used as the optical recording media. 2,6-Ionene-
TCNQ has the cations in the main chain of the polymers, while poly (1-butyl-4-vinylpyridinium-TCNQ) and poly(styrene co 1-butyl-2-vinylpyridinium-TCNQ) have cations in the side chain of the polymers. The side chain polymers were soluble in organic solvents and spin coatable. They were spin coated on the polycarbonate substrate with the aluminium reflective layer and tested by commercial optical recording media evaluation system. The maximum 40dB of CNR(carrier to noise ratio)was observed with the writing power of 8.9 mV and writing velocity of 1.2 m/s.
