一般描述

最好采用旋涂法。建议使用前通过 0.45 μm 膜片过滤器过滤分散物。涂层在最高温度 200°C 下干燥 1 min,但温度在 50°C 至 150°C 之间通常就足够了。干燥层的最佳厚度在 50-250 nm 范围内。
聚(3,4-乙撑二氧噻吩)-聚(苯乙烯磺酸盐)(PEDOT:PSS)是本征导电聚合物(ICP),由聚(3,4-乙撑二氧噻吩)(PEDOT)和聚(苯乙烯磺酸盐)(PSS)混合制得。它是水性乳液,其中PEDOT带正电,而PSS是反荷离子(带负电)。根据应用的不同,可以充当阳极或阴极材料。可用1000-5000 rpm的速度,将其旋涂在不同基底上。
聚(苯乙烯磺酸)阴离子掺杂聚(3,4-乙烯二氧噻吩)等导电聚合物 (PEDOT/PSS) 广泛应用于各种有机光电器件中。PEDOT:PSS 是阳离子聚噻吩衍生物的混合物,掺杂有聚阴离子。这类聚合物的高导电性和良好的抗氧化性使其适用于电磁屏蔽和噪声抑制。因此,发现聚合物薄膜在整个可见光谱中具有高透明度,甚至进入近 IR 和近 UV 区域,在 900-2,000 nm 处几乎 100% 吸收。400-800 nm 处无最大吸收。已研究小电场和小磁场对聚合物的影响。

应用

PEDOT:PSS和聚(9-乙烯基咔唑)(PVK)可以交联形成多层有机发光二极管。质子交换膜(如Nafion 212)可用PEDOT:PSS和聚(烯丙胺盐酸盐)(PAH)逐层涂覆。
在 OLED 和 PLED 器件中用作界面空穴注入层,降低工作电压、提高发光效率、延长显示寿命。
从900nm到2000nm几乎100%吸收。从400nm到800nm无最大吸收。 导电聚合物混合。

特点和优势

平均粒度更小,粒度分布更窄,可为 ITO 电极形成光滑表面,因此可降低 LED 设备短路的可能性。大幅降低的内在导电性可减少极小像素(小于 10 微米)矩阵阵列显示装置发生"串话"的可能性。

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page. You can contact any of our Customer Sales and Service offices to receive a quote.  USA customers:  1-800-325-3010 or view local office numbers.

  4. What is the Department of Transportation shipping information for this product?

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product. 

  5. Is this PEDOT:PSS, poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate), product p-doped or n-doped?

    This PEDOT:PSS product is based on hole-doped or P-type polymers. PEDOT can be n-doped, but the materials are too unstable to be of any commercial value.

  6. For product 560596, poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate), what is the relationship between film thickness and spin coating speed?

    Please see the attached chart showing the spin coating curve for product 560596, poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate).

  7. What is the temperature stability of this poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate), PEDOT:PSS, product?

    Deposited poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate), PEDOT:PSS, films can easily withstand temperatures in excess of 200°C for short duration and around 70°C in continuous service.  The aqueous dispersions of PEDOT:PSS, however, can be damaged by heating above 50°C for a prolonged period.

  8. How do I test the coductivity of poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate), PEDOT:PSS?

    Conductivity measurements should be performed on poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate), PEDOT/PSS, films deposited on flat substrates.  This dispersion should be deposited as a thin and homogeneous layer on a flat substrate using deposition techniques, such as spin-coating or doctor blading.  The layer thickness can be determined by scratching the film off the substrate in places with a razor blade and scanning the stylus of a mechanical or optical profilometer across the scratched region(s). The sheet resistivity can then be measured with conventional four-point probes.

  9. Can PEDOT:PSS, Poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate), coatings be etched?

    Yes, applied PEDOT:PSS films can be patterned by laser ablation.

Lithography, based on traditional ink-printing techniques, is a process for patterning various layers, such as conductors, semiconductors, or dielectrics, on a surface.

In the field of organic printable electronics, such as OLEDs and organic photovoltaics (OPVs), improved organic conducting and semiconducting materials are needed. The progress in two fields is reviewed in this article.

Conducting polymers such as polyaniline, polythiophene and polyfluorenes are now much in the spotlight for their applications in organic electronics and optoelectronics.
