## Description

- description: 'Modulating doping levels and nanofillers blending has facilitated
    optimization of electrical properties in polymeric nanocomposite films for thermoelectric
    applications. Herein we report, free-standing flexible films of ZnSb nanofillers
    contained PANI:CSA polymer nanocomposites, with varying ZnSb ratios, to realize
    carrier localization induced enhancement in power factor (≈ 10 times) and thermopower
    (≈ 6 times) within the protonated PANI:CSA. Structural, morphological, and chemical
    analyses revealed that ZnSb intercalation influences doping levels, expansion
    of interlayer spacing, structural disorder, and backbone conformation leading
    to transient localization amidst enhanced interchain hopping probability in the
    synthesized polymeric nanocomposites for realizing an enhanced thermopower ≈ 50
    μV/K with improved power factor ≈ 10 μW/m·K2. The tunable thermopower and localization–delocalization
    transitions is correlated with complex heterogeneous PANI structure, interchain
    interactions, and charge transport mechanisms, including carrier tunneling/hopping.
    These findings highlight the prospects of charge localization in improving the
    low and smeared Seebeck response in conducting polymers like PANI. '
