The Lifetime of OLEDs by ITO/glass substrates cleaning method and cathode deposition method were investigated in the fabrication of green light emitting OLEDs with $Alq_3$-C545T fluorescent system. In our experiments, the optimum cleaning method was obtained at last processing of boiling IPA(isopropyl alcohol). And the optimum deposition methode was obtained at 3 steps deposition rate of Al. The deposition rate of 3 steps progressed changing from $0.5\AA$/sec to $3\AA$/ sec. The green light emitting OLED with plasma treatment at 150W for 2 minutes showed the highest luminance and efficiency of 20000 cd/$m^2$ and 16 lm/W. On the contrary, the OLED device without plasma treatment showed much lower performance with the luminance and efficiency of 3500 cd/$m^2$ and 2 lm/W.

Vak, Doojin,Shin, Se jin,Kim, Dong-Yu 한국공업화학회 2003 응용화학 Vol.7 No.2

Polyfluorenes with spiro structure chains were synthesized. Dinydroanthracene containing polyfluorene derivatives showed nearly the same optical properties as polydialkylfluorenes, however, the polymer exhibited greatly enhanced thermal properties followed by reduced harmful aggregate formation. The photoluminescence emission of the polymer film showed pure blue emission even after annealing at 200℃ for 15 hours in air. Electroluminescence spectrum also showed high color purity. Triphenylamine containing polyfluorene derivatives were also synthesized. The polymer showed enhanced thermal properties as well as increased HOMO energy level which could improve the hole injecting and transporting properties.

The polyvinyl series organic films as gate insulators of thin film transistor(TFT) have been processed and characterized on the polyether sulphone (PES) substrates . The poly-4-vinyl phenol(PVP) and polyvinyl toluene (PVT) were used as solutes and propylene glycol monomethyl ether acetate(PGMEA) as a solvent in the formation of organic insulators. The cross-linking of organic insulators was also attempted by adding the thermosetting material, poly (melamine-co-formaldehyde) as a hardener in the compound. The electrical characteristics measured in the metal-insulator-metal (MIM) structures showed that insulating properties of PVP layers were generally superior to those of PVT layers. Among the layers of PVP series; copolymer PVP(10 wt%), 5wt% cross-linked PVP(10 wt%), copolymer PVP(20 wt%), 5 wt% cross-linked PVP(20 wt%) and 10 wt% cross-linked PVP(20 wt%), the 10 wt% cross-linked PVP(20 wt%) layer showed the lowest leakage current of 1.2 pA at ${\pm}10V$. The ms value of surface roughness and the capcitance per unit area are 2.41 and $1.76nF/cm^2$ in the case of 10 wt% cross-linked PVP(20 wt%) layer, respectively.

지구온난화 문제가 인류 생존을 위협하는 중대한 이슈로 떠오르면서 세계 각국은 온실가스 감축에 적극 나서고 있다. 대표적 온실가스인 이산화탄소(CO₂)는 석탄, 석유와 같은 화석연료를 연소하는 과정에서 대량으로 방출되고 있다. CO₂를 포집하고 저장하는 CCS (CO₂ Capture & Storage) 기술은 온실가스 저감의 대표적 기술로 세계 각국에서 연구가 활발하게 진행되고 있다. 본 연구는 대규모 CO₂ 배출원에서 포집된 CO₂를 대상으로, 국내 최초로 해상에서 지중저장을 하기 위한 고압 주입설비의 설계 및 구축에 관한 연구다. 이를 위해 2017년초 CO₂ 지중 주입설비가 구축되었으며 포항시 영일만 해상 플랫폼에서 CO₂ 시험주입을 국내 최초로 성공하였다. 그 결과 해상주입을 위한 주입설비의 운전 요구조건과 CO₂ 주입 특성이 파악되었고 주입장치 운영에 관한 노하우도 얻게 되었다. 시험주입에서 얻어진 결과는 향후 장치개선과 scale-up에 활용될 예정이다. Almost all countries of the world have recently made great efforts to reduce green-house gases to alleviate the global warming threatening human survival, because a huge amount of carbon dioxide as one of the main green-house gases has been emitted from the combustion processes of fossil fuels such as coal and oil. CO₂ capture and storage (CCS) technology is a representative method to diminish the green-house gases, and actively investigated by many countries. This study focuses on the design and construction of a high pressure CO₂ injection facility to store it to underground, which is the first CO₂ injection in Korea following the steps of the CO₂ capture from large CO₂ emission sources and transportation to the sea. Injection tests of CO₂ on the platform on the sea were carried out in Yeongil Bay of Pohang city in the early 2017. Thus, we were able to perceive the necessary operating conditions of the injection facility, injection characteristic, and knowhow of the injection facility. The results obtained from the injection test shall be utilized for facility upgrades and scale-ups.
