Membranes of Mn3O4 were obtained using the liquid phase exfoliation technique by probe sonication method. Exfoliation techniques have ease of scalability in obtaining desired amounts of material. We used iso-propyl alcohol (IPA) solution as a solvent for the exfoliation of the Mn3O4 samples obtained by co-precipitation. The sample to solvent ratio was of the order 1:500 mg/ml. The probe sonicator frequency was at 30 kHz and exfoliation was done in pulses of 10 s each, for 4 hours at room temperature. The probe sonicator temperature was maintained well within the range of 30 ± 2 ⁰C. The suspension was then sonicated and dried to obtain a powdered form.
