“…This low fluence is useful for technically induced changes in composite materials, as indicated before. [17][18][19][20][21] Additionally, the films' structural integrity can be compromised at fluence levels exceeding certain thresholds. The Ar+ beam was extracted using the hand-made ion source as previously reported, 22 as seen in Fig.…”

This work study the effects of argon beam irradiation on surface properties of CA/PANI films using cold cathode source with varying ion fluences (4×1014, 8×1014, and 12×1014 ions/cm2). The EDX, SEM and FTIR methods verified successful fabrication of the composites. Surface free energy, contact angle, and work of adhesion were measured for both the pure and irradiated films. Raising the ion flux from 4x1014 ions.cm-2 to 12x1014 ions.cm-2 it decreases the contact angle of CA/PANI from 62.1o to 43.4o and increases the surface free energy from 46.7 to 63.9 mJ/m2. The results showed that the CA/PANI changed after exposed to radiation, proving that the irradiated surface properties were improved. In addition, their electrical conductivity was tested in the frequency range of 50 to106 Hz for CA/PANI films. When subjected to 12x1014 ions.cm-2, the conductivity rose from 1.1×10-8 S/cm for CA/PANI to 6.5×10-7 S/cm. The results showed that the irradiated CA/PANI had better electrical and surface properties, which is crucial for many devices including batteries and supercapacitors

In this research, pure polyaniline (PANi), pure magnetite (Fe3O4), and then PANi/ Fe3O4 nanocomposites were prepared and characterized. FT-IR spectra of the prepared samples indicate successful polymerization of PANi onto Fe3O4. PANi/Fe3O4 nanocomposites exhibit broad absorption bands at specific wavenumbers, indicating the presence of various functional groups. The observed blue shift in certain peaks suggests the interaction between nitrogen atoms and oxygen atoms on the magnetite surface through hydrogen bonding. The intensity and wavenumber of the Fe3O4 band decrease, indicating weakened Fe–O bonds. These findings demonstrate a strong interaction and combination between PANi and Fe3O4 in the nanocomposites. Fe3O4 nanoparticles exhibit a regular spherical shape with an average diameter of 16 nm. However, they also show non-uniform size distribution due to aggregation into larger secondary particles, likely driven by attractive forces. PANi/Fe3O4 core-shell nanocomposites demonstrate clear morphological changes, with Fe3O4 nanoparticles well spread and wrapped by the PANi shell. The electron diffraction technique confirms the crystalline structure of Fe3O4 nanoparticles, showing diffraction rings consistent with magnetite. The results confirm the potential of incorporating magnetic Fe3O4 nanoparticles to impart magnetic functionality in the resulting PANi-based nanocomposite materials. Magnetic saturation measurements displayed an enhancement in magnetization with increasing Fe3O4 nanoparticles. The change in magnetic behavior for doped samples provides a means of tuning the magnetization strength of the composites to meet the application requirement such as data storage and magnetic sensors.
