本實驗研究 PEDOT : PSS材料經由縮合聚合法可以快速簡便的聚合。此實驗研究分為兩部份，首先是Part I.製備程序先將單體2,5-dibromo-3,4-ethylenedioxythiophene (DBEDOT)分別溶入溶劑(MeOH、Acetone)裡，再把聚(磺酸苯乙烯) PSS 與去離子溶液加入攪拌均勻，放置在溫度分別為 60、80、100、120℃的玻璃基板上，固定加熱時間20分聚合，即可成功得到PEDOT:PSS，將聚合出來的 PEDOT:PSS材料利用傅立葉轉換紅外線光譜儀、紫外光-可見光光譜儀進行檢測分析；另外，改變溶劑與去離子水的配比在固定溫度、時間下合成 PEDOT:PSS 材料並做上述的檢測鑑定分析。
將聚合好的PEDOT:PSS材料，用甲醇與去離子水將PSS清洗掉，得到固態 PEDOT 利用掃描式電子顯微鏡、穿透式電子顯微鏡可以得知PEDOT呈現圓板的形態，由傅立葉轉換紅外線光譜儀、XRD、紫外光-可見光光譜儀判定其確實為PEDOT材料以及用電子繞射進行檢測得知其為正交晶系。
實驗Part II.的部份是改變溶劑與水的配比也是上述DBEDOT 分別溶入溶劑 MeOH、Acetone 裡，再把 PSS 與去離子溶液加入攪拌均勻，
放置在溫度120℃下進行聚合，便可得到PEDOT:PSS。將PEDOT:PSS進行上述檢測分析；之後如同上述Part I方法即可得到PEDOT，得到的 PEDOT使用上述Pare I的儀器分析判定確實其為PEDOT材料。

This study concerns about preparing PEDOT: PSS material through condensation polymerization , which is quick and can be easily aggregated. This study is divided into two parts, the first is about the preparation procedure of the first monomer 2,5-dibromo-3,4-ethylenedioxythiophene (DBEDOT),which was dissolved in mixed solvent (MeOH, Acetone), then PSS and deionized solution were added with a uniform mixing, and placed at temperatures of 60,80,100,120 ° C respectively on a glass substrate, with a fixed heating time of 20 minutes for polymerization, and PEDOT:PSS can be successfully obtained PEDOT : PSS, the aggregation of the obtained PEDOT: PSS material can be characterized by FT-IR、UV - visible spectra were detected and analyzed; in addition, the ratio of solvent and deionized water were changed at fixed temperature. And time for the synthesis of PEDOT: PSS materials.
The obtained PEDOT: PSS materials was washed with methanol and deionized water to remove PSS to get the the PEDOT for SEM、TEM which showed that the shape of the PEDOT was cylindrical plate, FT-IR、 XRD、UV - Visible spectrometer wrer used to characterized the PEDOT materials and electron diffraction used to detect the crystal structure of the polymers.
Part II is to change the ratio of solvent and water and DBEDOT dissolved in the solvents of MeOH、Acetone ,respectively and then the PSS and the deionized solution stirring uniformly.Placed at a temperature of 120 ℃ can get the PEDOT: PSS. The PEDOT: PSS to used Part I analysis; after useing Part I method can be obtained PEDOT, and PEDOT used Part I analysis which were used to characterized the PEDOT materials.
