- This study reports the facile synthesis of highly conductive SrRuO3(SRO)–RuO2 composite nanofibre
mats and their potential suitability for application in electrochemical capacitors as an active electrode
material. SRO–RuO2/poly(vinyl acetate) composite nanofibre mats are electrospun on to a Au-coated
SiO2/Si substrate and a Ti substrate, subsequently thermocompressed at 60 ◦C, and calcined at various
temperatures (from 350 to 850 ℃). The calcined SRO–RuO2 nanofibre mats exhibit porous morphologies
and bundle shapes composed of multiple-fibrils with a nanoparticle diameter ranging from 20 to 50 nm.
Single SRO–RuO2 nanofibre and multiple SRO–RuO2 nanofibre mats show high electrical conductivity of
476 and 40.8 S cm−1, respectively. Pseudocapacitors using SRO–RuO2 nanofibre mats calcined at 350 ℃
exhibit a high specific capacitance of 192 F g−1 at a scan rate of 10mVs−1. The superior capacitance
retention (83.4%) of the SRO–RuO2 nanofibre mats is maintained even at rapid scan rate of 1000mVs−1.
