Electrochemical properties of ruthenium oxide (RuO<sub>2</sub>)/multi-walled carbon nanotube (MWCNT) composite electrodes for supercapacitors were investigated. The electrodes were prepared by impregnating MWCNT with different concentrations of RuCl<sub>3</sub>ㆍxH<sub>2</sub>O solution followed by chemical reduction and annealing at 150°C under a nitrogen atmosphere. Cyclic voltammetry results of 10 wt% RuO<sub>2</sub>/MWCNT composite electrodes demonstrated that the specific capacitance of the deposited RuO<sub>2</sub> electrode was significantly greater than that of pristine MWCNT and 5 wt% RuO<sub>2</sub>/MWCNT electrodes, respectively, in the same medium.

Generally, the basalt fibers/polypropylene composites have incomplete mechanical properties because basalt fibers have poor interfacial adhesion with polypropylene due to their imperfect interface. Therefore, in this study, the acid treatment on basalt fiber surfaces was carried out for improvement of interfacial adhesion between the basalt fiber and the polypropylene matrix. And, the correlation between mechanical properties and surface property changes of basalt fibers-reinforced polypropylene composites was studied at mechanical and energetic point of view.
