活性碳纖維布電極之電化學電容器，常藉由將導電高分子沉積於其上以增加電容量，電化學沉積的通常是以適當的電化學方法在固定單體的電解質中進行，但是這些方法也許會導致纖維布內部的孔洞被導電高分子阻塞而使離子阻力增加，故於此欲發展吸附聚合法以解決此問題。

單体吸附量可以經由將纖維布浸泡在不同濃度的苯胺而控制，吸附後再以電聚合使聚苯胺能於孔道內形成，於此以兩種電聚合法進行實驗，其一，A85，以定0.85V的電位進行聚合，其二，A65，先在0.85V進行聚苯胺成核後，再將電位轉至0.65V進行聚苯胺的成長。
以聚苯胺改質之碳纖維布複合電極以循環伏安法進行測試並且分析，當少量的聚苯胺沉積在碳纖維內部時，其造成之阻力並不大，而若是太多量的沉積則會因聚苯胺的阻塞孔洞而使內部總阻力明顯上升。

聚苯胺、聚苯胺改質之活性碳纖維布電極以及組合之電容器的電容及阻力亦在這裡被研究，聚苯胺的比電容通常隨著沉積量增加而減少，其原因可能是氮原子與共同離子的結合隨著聚苯胺本身結構阻塞程度而增加；在A85-20的電極與組裝之電容器同時擁有好的電容表現極低的阻力，A65系列可以使組裝之電容器阻力值降至ACF電容器的一半。

Capacitance enhancement of activated carbon fabric employed as electrode material for electrochemical capacitors was conducted by electrochemical deposition of conductive polymer. Electrochemical deposition of conducting polyaniline onto the carbon was always carried out in electrolyte contains monomer and different electrochemical methods were applied properly. But these methods may block electrolyte into pore of the carbon material from outside and lead to increase of resistance of ion so that the Adsorption-Polymerization Method was developed in this work.

Different amounts of adsorbate on the carbon can be varied by concentration of aniline monomer in adsorption process. After adsorption, electropolymerization was carried out in two potential step methods in order to form the polyaniline oligomer inside the pores of carbon. The potential of the first method, A85, was hold at 0.85V during the polymerization process. The second method, A65, was applied to 0.85V for nucleation, and followed by 0.65V for growth the polymer chains.

The cyclic voltammetry experiment was performed used to analyze the PANI-modified composite electrodes. As the suitable amount of polyaniline deposited inside the activated carbon fiberic the ion migration resistance could be small, and as the amounts increase the resistance increased suddenly due to polyaniline block the pores of the activated carbon fibers.

The electrochemical properties of loaded polyaniline, the PANI-modified composite electrodes and assembled capacitors were investigated here, including the capacitance and resistance. The specific capacitance of polyaniline usually decrease with the amount of deposition probably due to the increasing extent of obstructing N-atom from counter ion binding； the capacitance of the electrodes had a maximum at A85-20 and also had good performance of capacitance and low overall resistance in the assembled A85-20 capacitor. The A-65 set could reduce the resistance to half of the ACF capacitor.
