Transition
metal oxides (TMOs) are of great interest for their catalytic stability and
semi-conductive properties. For supercapacitor electrodes, TMOs are used to
alternative materials due to the enhancement
of energy density and specific capacitance. In this study, molybdenum trioxide- octadecylamine (MoO₃-ODA)
and molybdenum trioxide- EO_nPO_mEO_n-type block-copolymer
composite thin films on ITO were prepared by Spin Coating method.  MoO₃-ODA/ITO and MoO₃-Pluronic®F127/ITO
electrodes were fabricated with above mentioned thin films and their
electrochemical properties were investigated. Our results demonstrated that
electrical conductivity increased in the presence of ODA and Pluronic®F127 (EO₁₀₆PO₇₀EO₁₀₆).
Furthermore, molybdenum trioxide composite structure prepared with Pluronic®F127 shown better
electrochemical energy storage capacity. Our electrochemical studies and
results show that MoO₃ composite structures with Pluronic®F127 can be a promising approach to fabricate
new generation high-performance
supercapacitors.

Molibden Oksit-Oktadesilamin/Pluronic®F127 Kompozit Elektrotların Kapasitif Özelliklerinin İncelenmesi

Öz

Geçiş metal oksitleri (GMO), katalitik
aktiviteleri ve yarı iletkenlik özellikleri ile ilgi görmektedirler.
Süperkapasitör elektrotlar için de spesifik kapasitansı ve enerji yoğunluğunu
artırmak amacıyla GMO’lar alternatif malzemeler olarak kullanılmaktadır. Bu
çalışmada, molibden trioksit-oktadesilamin (MoO₃-ODA) ve molibden
trioksit- EO_nPO_mEO_n-
tipi blok-kopolimer
kompozitlerinin ITO cam altlık üzerine döndürerek kaplama (Spin Coating, SC)
yöntemiyle ince filmleri hazırlanmıştır. Hazırlanan bu ince filmlerle MoO₃-ODA/ITO
ve MoO₃-Pluronic®F127/ITO elektrotlar üretilmiş ve bu elektrotların
elektrokimyasal özellikleri araştırılmıştır. Elde edilen bulgular ODA ve
Pluronic®F127 (EO₁₀₆PO₇₀EO₁₀₆)’nin varlığında
elektriksel iletkenliğin arttığını, ayrıca Pluronic®F127 ile hazırlanan molibden
trioksit kompozit yapıların daha iyi elektrokimyasal enerji depolama
kapasitesine sahip olduğunu göstermiştir. Elektrokimyasal
çalışmalarımız ve elde edilen bu sonuçlar, Pluronic®F127 katkılı MoO₃ kompozit yapılarının yeni nesil yüksek
performanslı süperkapasitörlerin üretilmesinde umut verici bir yaklaşım
olduğunu göstermektedir.
