Area of Science:

  • Materials Science
  • Nanotechnology
  • Solid State Physics

Background:

  • Polymer nanocomposites (PNCs) offer tunable properties by incorporating nanoparticles.
  • Cobalt ferrite nanoparticles (CoFe₂O₄ NPs) exhibit unique magnetic and microwave absorption characteristics.

Purpose of the Study:

  • To synthesize and characterize polymer nanocomposites using Rogers polymer and CoFe₂O₄ NPs.
  • To investigate the magnetic properties and microwave absorption of these PNCs with varying CFO NP concentrations.

Main Methods:

  • Synthesis of PNCs with different weight percentages of CFO NPs.
  • X-ray diffraction (XRD) for crystal structure analysis.
  • Transmission electron microscopy (TEM) for nanoparticle dispersion.
  • Magnetic measurements (blocking temperature, saturation magnetization, coercivity).
  • Microwave absorption measurements.

Main Results:

  • Uniform dispersion of 10 nm ± 1 CFO NPs in the polymer matrix confirmed by TEM.
  • Superparamagnetic behavior observed near room temperature with a consistent blocking temperature (T(B)≈298 K).
  • Saturation magnetization increased from 11 emu g⁻¹ (30 wt% CFO) to 32 emu g⁻¹ (80 wt% CFO).
  • High coercivity (H(c) = 19 kOe at 10 K) independent of CFO loading.
  • Significant microwave absorption in 80 wt% CFO PNC, with quality factor enhanced by applied magnetic field.

Conclusions:

  • The synthesized PNCs exhibit promising superparamagnetic properties and tunable magnetic responses.
  • The 80 wt% CFO loaded PNC demonstrates significant potential for microwave absorption applications.
  • The consistent blocking temperature and coercivity suggest robust magnetic behavior irrespective of nanoparticle loading.
