Abstract
Smart windows, which have electrically controlled transmission and zero energy consumption when in a coloured or colourless state, improve building energy efficiency because they have the potential to significantly reduce the energy costs of lighting, heating, and cooling, which are addressed by electrochromic and supercapacitors. Both electrochromism and electrochemical energy storage share the same electrochemical principles of redox reactions that occur when the charge is inserted into or removed from the electrode. Composite materials have been widely used for electrochromic applications, as they have the potential to exhibit the advantages of their constituents. A conjugated polymer-based composite is a popular option due to the conductivity and flexibility of conjugated polymers. The challenge in forming a high-performance composite material is to achieve synergistic effects in desired aspects instead of getting the average performance of the components. Thus, the thesis is aimed at creating new conjugated polymer-based composite systems in which the conjugated polymers and other components are complementary in some ways, as well as investigating how interfacial interactions affect the synergistic effects of complementary components in conjugated polymer-based electrochromic composites. The fundamental idea is that, with the right structural composition, strong interfacial interactions between conjugated polymers and the other components can have large synergistic effects, favorably impacting electron transport, oxidation/reduction potentials, and electrochemical stability. To verify the hypothesis, different composite systems have been studied are polyaniline, reduced graphene oxide, nickel oxide, and Prussian blue. The components have complimentary conductivity and mechanical features. The materials studied have improved electrochromic and electrochemical characteristics. Strong interfacial interactions between the composite’s ingredients are demonstrated, as are considerable synergistic effects. The findings give justification for developing high-performance composite materials for electrochemical and electrochromic applications.
