摘要

我们的工作重点是纳米复合聚[2-甲氧基，5-(2 ' -乙基-己氧基)-苯基乙烯](MEH-PPV)共混物与碳纳米管(CNTs)和二氧化钛(TiO2)。研究了MEH-PPV:CNTs:TiO2纳米复合薄膜随厚度的增加在光照下的电导率。随着厚度的增加，电导率从6.7 × 10−6 S/m下降到0.6 × 10−6 S/m。同时，室温(300 K)紫外可见光谱膜在500 ~ 510 nm处有透射峰。随着厚度的增加，透射率峰值从65 T%下降到10 T%，光学带隙从1.9、2.0、2.05和2.1 eV增加。

Effect of thickness on the transparency of nanocomposited MEH-PPV:CNTs:TiO2 thin film

Our work focuses on nanocomposited poly [2-methoxy, 5-(2′-ethyl-hexyloxy)-phenylenevinylene] (MEH-PPV) blend with carbon nanotube (CNTs) and titanium dioxide (TiO2). The conductivity under illumination of the nanocomposited MEH-PPV:CNTs:TiO2 thin film was investigated with the thickness increased. The conductivity showed decrement in value from 6.7 × 10⁻⁶ to 0.6 × 10⁻⁶ S/m as the thickness increased. Mean while, the UV-vis spectra films at room temperature (300 K) showed a transmittance peak at 500 – 510 nm. The transmittance peaks reduced from 65 T% to 10 T% as the thickness increased while the optical band gap increased from 1.9, 2.0, 2.05 and 2.1 eV.
