                            <p>Bu makale çalışmasında psedo-süperkapasitörler için mangan dioksit (MnO2)/ polianilin (PANI)/ tek duvarlı karbon nanotüp (SWCNT) nanokompozit elektrot hazırlanmıştır. Elektrotun iç direcini azaltmak, kapasitans stabilitesini arttırmak ve tek duvarlı karbon nanotüp maliyetini azaltmak için SWCNT iki aşamalı asitle aşındırma çalışması yapılmıştır. SWCNT ~%95 saflıktan %99,98 saflığa ulaştırılmıştır. Ayrıca bu işlemle SWCNT fonksiyonelleştirilmiştir. Böylece SWCNT çevresine PANI kaplanarak nanokompozit oluşturulmuştur. Hidrotermal yöntem ile MnO2/PANI/SWCNT sentezlenmiştir. Sentezlenen nanokompozit yapının morfojik, kimyasal ve termal analizleri gerçekleştirilmiştir. Bununla birlikte kristal yapı tayini için X ışını difraksiyometresi (XRD) kullanılmıştır. Elektrokimyasal analizler üçlü elektrot sistemiyle 1 M KOH elektrolit çözeltisinde yapılmıştır. Döngüsel voltametri (CV), galvanostatik şarj-deşarj (GCD) ölçümleri alınmıştır. Nanokompozit elektrodun 400 döngüde kapasitansı 314 mF/cm2 olarak bulunmuş kapasite tutma kararlılığı ise %73,24 olarak hesaplanmıştır. Yapılan çalışma sonucunda kapasitans kararlılığının yüksek olduğu ve süperkapasitörün redoks tepkimelerine duyarlı olduğu gözlemlenmiştir.</p></trans-abstract>

To reduce the internal resistance of the electrode, increase the capacitance stability, and reduce the cost of single-walled carbon nanotubes, SWCNT was subjected to two-step acid etching. The purity of SWCNT was improved from ~95% to 99.98%. In addition, SWCNT was functionalized by this process. Thus, a nanocomposite was formed by coating PANI around SWCNT. MnO2/PANI/SWCNT were synthesized using the hydrothermal method. Morphological, chemical and thermal analyses of the synthesized nanocomposite structure were carried out. In addition, X-ray diffraction (XRD) was used to determine the crystal structure. Electrochemical analyses were performed using a three-electrode system in a 1 M KOH electrolyte solution. Cyclic voltammetry (CV) and galvanostatic charge-discharge (GCD) measurements were performed. The capacitance of the nanocomposite electrode at 400 cycles was 314 mF/cm2, and the capacitance retention stability was calculated at 73.24%. The results showed that the capacitance stability was high, and the supercapacitor was sensitive to redox reactions.</p></abstract>
