The precise selection and control of the working potential during electro-polymerization and metal oxide integration using the linear sweep voltammetry was key for synthesizing the polymer hybrid electrodes reproducible and with defined composition and structure. The PNZF electrode demonstrated the highest specific capacitances of 816 F g⁻¹ and 791.3 F g⁻¹ at a scan rate of 5 mV s⁻¹ and 1.0 A g⁻¹ current density, along with high power density and energy density of 1058.4 W kg⁻¹ and 136.4 Wh kg⁻¹, and with excellent stability retaining 90 % over 4000 cycles. We could attribute the excellent performance to a low charge transfer resistance of 25.0 Ω, a predominantly surface-controlled charge storage mechanism, and a porous morphology with uniform distribution of ZnFe₂O₄ particles in the polymer network, all resulting from the electrochemical synthesis method.

A family of four polymers, namely PAQM3T, PAQM4T, PAQM2T-TT and PAQM2T-TVT, designed with different comonomers, is studied using cyclic voltammetry, galvanostatic charge/discharge cycling, electrochemical impedance spectroscopy and spectroelectrochemistry. While p-AQM molecules are known to be relatively unstable, it is demonstrated here that the Q-D polymers can be reversibly oxidized, indicating that p-doping does not generate highly reactive radical species on the methylene carbons of the alkoxy-substituted p-AQM units. This distinctive behavior of polymers <em>vs</em> small molecules can be attributed to a more efficient delocalization of radicals over the conjugated backbone. However, it is found that electrochemical performances and stability depend strongly on the nature of the donor unit. PAQM2T-TVT, having enhanced quinoidal character due to the presence of planar thiophene-vinylene-thiophene (TVT) units in its backbone, exhibits the highest specific and areal capacitance values (331 F/g and 83 mF/cm², respectively) as well as improved capacitance retention upon galvanostatic cycling, up to 92 % after 200 cycles. Moreover, PAQM2T-TVT also shows remarkably improved rate capability, withstanding current densities as high as 10 mA/cm², owing to higher electronic and ionic conductivity.

Therefore, the progress in fabrication processes of organic, inorganic and their hybrid aerogels has been extensively grown nowadays to obtain desirable TE aerogels and overcome their limitations in terms of low figure of merit (<em>zT</em>), scalability, mechanical durability, long-term stability, and reliability of flexible and stretchable thermoelectric aerogels are challenges today.

Therefore, this study does not only introduce a summary of recent works in terms of their (organic, inorganic, and/or hybrid) structures, fabrication methods, TE functions, and key factors impacting TE functions and their related mechanisms, but it answers some important questions such as: Why is the aerogel considered as an important TE material?. And another question is: Is it possible to achieve a polymeric (PEDOT:PSS and/or others) aerogel with high electrical conductivity σ &gt; 100 Scm⁻¹ and low thermal conductivity <em>k</em> &lt; 100 mWmK⁻¹ without any additives?.
