The optical, thermal, structural, and broadband dielectric and electrical properties of these PB films are characterized in detail employing advanced instruments and interpreted meaningfully with blend compositions. The ultraviolet–visible (UV–Vis) spectroscopic results confirmed predominantly composition tunable UV absorbance as well as energy bandgap values of these PB films, which decreased when the P(VDF-HFP) amount was relatively reduced. Differential scanning calorimetry (DSC) measurements explained the reduction in the degree of crystallinity and crystallite thermal stability on decreasing the P(VDF-HFP) amount in the blend and also their transformation to amorphous type miscible blend for the compositions having PMMA amount exceeding 60 wt%. The Fourier transform infrared (FTIR) spectra also elucidated the formation of miscible blends for PMMA-rich compositions owing to a large increase in heterogeneous hydrogen bonding. The broadband dielectric spectroscopic measurements over the nine decades of harmonic electric field frequency (20 Hz to 1 GHz range) unveiled the contribution of various polarization processes and their alteration with frequencies that govern the dielectric permittivity and its dispersion, and different relaxations related to the structural dynamics of the blended polymers.

The use of lignin resulted in numerous advantages including an increased number of functional groups, satisfactory biocompatibility, low toxicity, and high carbon content. The major benefit of lignin is associated with the reduced carbon footprint of the manufactured product. Lignin can be classified as a natural flame-retardant agent owing to the high amount of char formed during combustion. In turn, TiO₂ exhibits high chemical stability and low operating costs and is considered a non-toxic and environmentally friendly material. During the experiments, commercial TiO₂ in anatase crystallographic form, TiO₂ synthesized from titanyl sulfate hydrate, and kraft lignin as well as organic–inorganic hybrid materials composed of these materials were evaluated as functional additives in epoxy-resin-based polymer coatings (Epidian 601) and their properties were investigated in detail. The cone colorimetry test confirmed that the obtained hybrids are effective flame-retardant additives for polymer coatings, with a notable fire hazard reduction observed for samples containing a synergistic system of titanium oxide and lignin. The coating with lignin was the most effective in fire suppression processes. The conducted thermal and mechanical investigations confirmed good performance properties of the coatings indicating thermal resistance up to 360 °C and Shore D hardness in a range of 80.36–86.28°Sh, accordingly.
