Investigation of AC Electrical Properties of MXene-PCL Nanocomposites for Application in Small and Medium Power Generation

The paper examined Ti3C2Tx MXene (T—OH, Cl or F), which is prepared by etching a layered ternary carbide Ti3AlC2 (312 MAX-phase) precursor and deposited on polycaprolactone (PCL) electrospun membrane (MXene-PCL nanocomposite). X-ray Diffraction analysis (XRD) Scanning Electron Microscopy (SEM) indicates that the obtained material pure Ti3C2 MXene. SEM of PCL-MXene composite demonstrate random distribution over nanoporous membrane. Results capacitance, inductance, phase shift angle studies MXene-PCL nanocomposite are presented. It was found frequency dependence capacitance exhibited clear sharp minima in range 50 Hz to 104 Hz. inductance shows maxima, position exactly coincides with for occurrence parallel resonances. Current conduction occurs electron tunneling between nanoparticles. In from about 105 Hz, there broad minimum relationship. this maximum angle—its amplitude close 90°. real value layer determined be 1 H. average distance tunnels some approximation 5.7 nm expected relaxation time ?M ? 3 × 10?5 s.
