Polymer-based composite materials have attracted significant attention in recent years due to their low
density, ease of processing, and adjustable multifunctional properties. In this study, magnetic functional
polymer nanocomposites were successfully produced by adding nanoparticles to a polymer mixture.
Comprehensive characterization was performed using TGA, DSC, FTIR, XRD, SEM, and PPMS
techniques to systematically evaluate the thermal, structural, morphological, and magnetic properties of
the developed materials.
Thermogravimetric analysis showed that thermal stability improved significantly after the addition of
nanoparticles, as evidenced by an increase in the onset decomposition temperatures and an increase in
the residual mass values. Differential scanning calorimetry results revealed filler-dependent changes in
melting temperature and crystallization behavior, particularly at high filler content (40 wt%), indicating
a strong effect on polymer chain mobility and crystalline organization. FTIR spectra confirmed that no
new covalent bonds formed between the nanoparticles and the polymer matrix, while indicating the
presence of intermolecular interactions, most likely hydrogen bonds. XRD analyses revealed that the
semi-crystalline polymer matrix was preserved as the dominant phase, while the characteristic crystal
peaks of iron oxides were significantly suppressed due to nanoscopic distribution and homogeneous
dispersion. SEM observations showed that nanoparticles were relatively homogeneously distributed at
low filler ratios.
In conclusion, the addition of nanoparticles to the polymer matrix effectively adapts the multifunctional
performance of PCL–PVA nanocomposites, and these materials have been determined to hold strong
potential for advanced applications such as sensing, actuation, biomedical engineering, and magnetic
separation technologies.
