Special Issue Information

Dear Colleagues,

Despite the natural cycle of climate change being an unavoidable reality, history has told us that when past civilizations overstretched themselves or pushed the consumption of natural resources to the edge, the consequences of climate change soon became amplified. We are in a critical period full of challenges and opportunities to address climate change by developing environmentally responsible and sustainable energy technologies. The applications of advanced functional thin films, ranging from the quantum level to nano- and microscale, from inorganic metal oxides to conductive polymers, have been driving the rapid development of energy-saving technologies as well as clean and renewable energy production, storage and conversion in the past decade.

This Special Issue aims to collect fundamental and applied original research and review articles on advanced thin films and their roles in reliable renewable energy devices and/or systems, including but not limited to supercapacitors, flow batteries, fuel cells, electrolysis, solar fuel generators, triboelectricity, etc.

This paper reports on the linear colorimetric and electrochromic (EC) characteristics of electrodeposited polyaniline (PANI) films. This paper also investigates the infrared EC properties of acid-doped PANI films. The electrochemical polymerization method was employed to create a porous and thin PANI film layer onto PET-ITO substrates. This layer was capped with WO3 film to create a gel electrolyte sandwich structure that demonstrates the compatibility of PANI films with cathodic WO3 films in full devices. The electrodeposition of the film was fabricated by applying different voltages and time, with the optimal film quality achieved with the 1.7 V voltage and a 20 min deposition period. The surface morphology, optical performance, electrochemical behavior, and molecular structure evolution are comprehensively studied in this work. The linear colorimetric behaviors and the corresponding significant changes in the structure in Raman spectra build direct strong quantitative relations in EC polymers. The well-defined oxidation and reduction peaks observed in the cyclic voltammetry indicate the ion-diffusion dominant process in the electrochromism of PANI. Significant transitions between the benzene and quinone phases in the Raman spectra are found in the bleached and colored states of polymers. This study enhances the understanding of PANI film structure and electrochemical and associated optical properties, providing more insights into the dual-function EC charge storage polymers and other energy-related functional materials.
