초록
저렴한 비용으로 도전성 투명 필름을 제조하기 위해 PET 필름 위에 습식 도포법으로 ITO/ATO 막을 적층시켰다. 압력 15 MPa, 온도 50℃의 SAS 합성 조건으로 ITO를 합성하였으며 ITO의 최적 조성비(In/Sn)는 65, 합성된 ITO의 평균입경은 15 ± 2 nm, 표면저항 값은 4 × 104 Ω.cm였다. 도포액은 pH 10에서 제조하였으며 ATO 막의 표면조도(Ra), 표면저항값, 빛투과율은 각각 9 nm, 5.5 × 106Ω.cm, 91%였다. 일차 도포된 ATO 막 위에 0.1, 0.5, 1.0, 2.0 ITO wt% 첨가한 도포액으로 ITO 막을 적층 제조하였으며, ITO/ATO 적층 필름의 표면조도는 4, 10, 12, 16 nm이였으며 표면저항 값은 각각 3.7 × 106, 2.4 × 106, 8 × 105, 2 × 105Ω.cm로 측정되었다. 적층 필름의 빛투과율은 각각 89, 88, 86, 82%이였으며 ITO 농도가 높아질수록 빛투과율은 낮아졌다.
The multi-layer PET film of ITO/ATO was prepared by a wet coating method to obtain the transparent film with a high conductance at low cost. ITO nano-particles were synthesized by a SAS method at 15 MPa and 50 ℃, where optimized rate of In/Sn was 65. Average diameter and resistivity of ITO obtained from SAS are 15 ± 2 nm and 4 × 104 Ω.cm. Coating solution was prepared at pH 10. Roughness (Ra), resistivity, and transmissivity of ATO film on PET are 9 nm, 5.5 × 106Ω.cm, and 91%. The multi-layered film of ITO/ATO was obtained by solution including 0.1, 0.5, 1.0, and 2.0 ITO wt% on ATO layer. Roughness (Ra) of multi-layered film with 0.1, 0.5, 1.0, and 2.0 ITO wt% is 4, 10, 12, and 16 nm, respectively. Corresponding resistivity with an increasing ITO concentration is 3.7 × 106, 2.4 × 106, 8 × 105, and 2 × 105Ω.cm. Transmissivity of ITO/ATO film decreases as 89, 88, 86, and 82% with an increasing ITO concentration as 0.1, 0.5, 1.0, and 2.0 wt%.
