X-ray diffraction (XRD) revealed a decrease in the crystallinity of the HPMC/CS matrix upon incorporation of NiFe₂O₄ NRs. Fourier-transform infrared (FT-IR) analysis confirmed interactions between the polymer matrix and the nanorods. UV-Vis spectroscopy indicated improved optical properties in the composites. Notably, the indirect optical bandgap decreased from 5.19 eV to 4.43 eV for blends containing 8 wt% NiFe₂O₄ NRs, suggesting potential applications in light absorption or manipulation. The AC conductivity of the nanocomposites increased compared to the pristine HPMC/CS blend. Furthermore, both dielectric permittivity and modulus displayed tunability with varying NiFe₂O₄ NR concentrations, making these materials promising candidates for applications requiring controlled dielectric responses. Magnetic measurements revealed enhanced coercive field and saturation magnetization compared to the pure HPMC/CS blend, suggesting potential applications in magnetic field sensing or data storage. An engineered HPMC/CS- NiFe₂O₄ nanocomposite capacitor exhibited improved storage capacity and controllable conductance characteristics. These findings suggest promising applications for these nanocomposites as bandgap tuners, optical sensors, permittivity-tunable dielectrics, and novel host matrices for solid polymer electrolytes.

The Ag/TNT samples were annealed between 70 and 350 ºC to optimize the properties and functionalities of the composite material. The Ag/TNTs were characterized using X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), Fourier-transform infrared spectroscopy (FT-IR), UV–Visible spectroscopy (UV–Vis), and UV–Visible diffuse reflectance spectroscopy (UV–Vis DRS). XRD analysis revealed the formation of silver titanate through the exchange of extra-framework Na⁺ ions in TNTs with Ag⁺ ions. New peaks at 28.3° and 48.2° appeared in the XRD pattern of Ag/TNTs-350, indicating a partial transformation of the nanotabular TNTs to anatase nanotubes due to the temperature change. The interaction observed between the Ag and TNT particles is believed to be linked to a distinct medium band at 1384 cm⁻¹. This band possibly indicates that silver ions may interact with oxygen or nitrogen-containing groups on the surface of the TNT particles. HRTEM analysis revealed that the inclusion of AgNPs did not significantly alter the original nanotube morphology of TNTs, except in the Ag/TNTs-350 sample, which exhibited structural flaws and uneven walls. The bandgap reduction from 2.7 eV in TNTs-100 to 2.2 eV in Ag/TNTs-350 underscores the impact of AgNPs and annealing on modulating electronic properties and improving photocatalytic performance.

The interaction of Ag-TNTs with titanate/titania crucially influences visible light activity, with degradation rates consistently increasing as annealing temperatures rise.
