聚3,4-乙烯二氧噻吩:聚苯乙烯磺酸(PEDOT:PSS)發展至今已在許多電子產品中看見，應用層面相當廣，主要是因為優秀的光學性質及相對穩定的製程，使其在商業的應用上相對其他導電高分子來的廣泛。現有製造導電高分子的方式相當多種，但常需要在極端pH環境下並使用強氧化劑來進行反應，製程過程對環境的影響難以完全避免，因此本研究利用酵素辣根過氧化酶來催化合成PEDOT:PSS。利用酵素聚合反應相對緩和的反應過程避免對環境的危害，也藉由酵素作為催化劑使反應能夠持續，使合成效果更好。
本研究討論面向相當廣，研究改變製程方式，以微波消化器給與能量代替以往使用恆溫水槽作為加熱方式成功縮短合成PEDOT:PSS反應所需的時間，並研究有無酵素在不同加熱方式的結果;使用熱處理的方式來改變PEDOT:PSS薄膜的性質使其不溶於水中;利用旋轉塗佈方式塗佈導電高分子薄膜，利用SDS溶劑及熱處理的方式來改變薄膜性質，期望能提升其導電度；利用過氧化氫來進行降解PEDOT:PSS的氧化反應，並添加FeCl2來催化過氧氫根自由基的產生，達到快速降解PEDOT:PSS導電高分子的目的，並建立降解的方法。

To date,Poly 3,4-ethylenedioxythiophene: polystyrene sulfonic acid (PEDOT:PSS) has been developed in many electronic products, and its application level is quite wide, mainly due to excellent optical properties and stable and relatively stable processes. It is widely used in commercial applications relative to other conductive polymers. There are many ways to manufacture conductive polymers, but it is often use some strong oxidant in an extreme pH environment to react. It is difficult to avoid the environmental impact from the process. To avoid this, in this study uses the enzyme horseradish peroxidase to catalyze the synthesis of PEDOT:PSS, using the relatively mild reaction process of the enzyme polymerization to avoid environmental damage, and also uses the enzyme as a catalyst to control the reaction wide, so that the synthesis process is much better. This study is quite wide. In order to shorten the time for synthesize PEDOT:PSS, we chang the heating methods, using Microwave Digestion System instead of the traditional water bath as a heating source and to evaluate results of the presence or absence of enzymes in different heating methods; The research use the method of heat treatment to change the properties of PEDOT:PSS film to make it insoluble in water. The conductive polymer film is coated by spin coating method, and the properties of the film are changed by SDS solvent and heat treatment. We use hydrogen peroxide to degrade the oxidation reaction of PEDOT:PSS, and add FeCl2 to catalyze the generation of peroxygen radicals. It is expected to rapidly degrade PEDOT:PSS conductive polymer.
