“…These properties stimulate the market demand, which in turn encourages the development of the technology. Because the work function of CNTs is ∼4.5–5.2 eV, which is close to that of ITO, CNT TCFs with low sheet resistance and high transmittance have the great potential to replace ITO as the anode material in the fabrication of OLEDs, especially for flexible devices. − The essential properties of some CNT TCF-related anodes have been summarized in Table . Basically, an ideal OLED would have low roughness (in order to have low leakage current) and turn-on voltage along with a high maximum light output and current efficiency.…”

Recent Development of Carbon Nanotube Transparent Conductive Films

Transparent conducting films (TCFs) are a critical component in many personal electronic devices. Transparent and conductive doped metal oxides are widely used in industry due to their excellent optoelectronic properties as well as the mature understanding of their production and handling. However, they are not compatible with future flexible electronics developments where large-scale production will likely involve roll-to-roll manufacturing. Recent studies have shown that carbon nanotubes provide unique chemical, physical, and optoelectronic properties, making them an important alternative to doped metal oxides. This Review provides a comprehensive analysis of carbon nanotube transparent conductive films covering detailed fabrication methods including patterning of the films, chemical doping effects, and hybridization with other materials. There is a focus on optoelectronic properties of the films and potential in applications such as photovoltaics, touch panels, liquid crystal displays, and organic light-emitting diodes in conjunction with a critical analysis of both the merits and shortcomings of carbon nanotube transparent conductive films.

“…The evenly distributed structure of CNTs is also apparent in the AFM image in Figure 3e. The roughness of TCFs is closely related to the uniform brightness of the OLEDs [57], so it was necessary to test the surface morphology of TCFs. Perfect TCFs will have low roughness.…”

High-Performance Transparent PEDOT: PSS/CNT Films for OLEDs

et al. 2021

Improved OLED systems have great potential for next-generation display applications. Carbon nanotubes (CNTs) and the conductive polymers poly (3,4-ethylenedioxythiophene): poly (styrene sulfonate) (PEDOT: PSS) have attracted great interest for advanced applications, such as optoelectronic products. In this paper, the simultaneous enhancement of the conductivity, roughness, and adhesion properties of transparent conductive films with PEDOT: PSS/CNTs is reported. These films prepared by a simple spin-coating process were successfully used to produce high-performance organic light-emitting diodes (OLEDs) with an improved lifetime. Addition of PEDOT: PSS lowered the film sheet resistance and CNTs helped to enhance the stability and maintain the lifetime of the OLEDs. In addition, treatment with methanol and nitric acid changed the morphology of the polymer film, which led to greatly reduced sheet resistance, enhanced substrate adhesion, and reduced film roughness. The best performance of the film (PEDOT: PSS: CNT = 110: 1, W/W) was 100.34 Ω/sq.@ 90.1 T%. High transmittance, low sheet resistance, excellent adhesion, and low roughness (3.11 nm) were achieved synchronously. The fabricated OLED demonstrated a low minimum operating voltage (3 V) and could endure high voltage (20 V), at which its luminance reached 2973 cd/m2. Thus, the incorporation of CNTs within PEDOT: PSS electrodes has great potential for the improvement of the performance of OLED devices.

A novel chiral poly(amide-imide) (PAI) containing triptycene and S-valine moieties was prepared from the polycondensation reaction of N,N′-(pyromellitoyl)-bis-S-valine diacid chloride with bis(4-aminophenoxy)phenyl triptycene. The new PAI/α-Fe 2 O 3 nanocomposites were prepared via ultrasonic irradiation process by dispersing silane coupling agent modified α-Fe 2 O 3 nanoparticles in the polymer matrix. The resulting nanocomposites were characterized by Fourier transform infrared, powder X-ray diffraction, transmission electron microscopy (TEM), and thermogravimetric analysis (TGA). The TEM results indicated that the nanoparticles were dispersed homogeneously in PAI matrix on nanoscale. TGA confirmed that the thermal stability of the nanocomposite was improved in the presence of α-Fe 2 O 3 nanoparticles.
