摘要: Abstract This paper reports efficient liquid-liquid extraction strategies for concentrated suspensions of oxide particles and demonstrates the benefits using such thin film applications fabrication supercapacitor electrodes. We performed materials synthesis in an aqueous phase achieved transfer to organic phase, avoiding agglomeration during drying stage. The metal oxides, suspended solvent were used directly deposition polymer-titania composite films Mn3O4-carbon nanotube electrodes supercapacitors. Strategy E1 involved modification in-situ a Schiff base reaction with extractor at interface. In one-step E2 procedure interface reactions extraction. discuss advantages strategies. Both featured biomimetic approach surface particles, which allowed strong adsorption extractors. ability perform Mn3O4–carbon high active mass loading. showed capacitance 2.63 F cm−2, good retention charge-discharge rates low impedance. results this investigation pave way agglomerate free processing various functional advanced films, coatings devices
