The development of flexible electronic devices, particularly flexible andbendable energy storage devices, has catalyzed significant interest in the research offlexible composite materials. In this study, conductive paper membranes weresynthesized by polymerizing polypyrrole (PPy) on the surface of cellulose fibers.The cellulose material, derived from cardboard, underscores an eco-friendlyapproach to waste reduction and environmental protection. Characterization of thecellulose/PPy conductive membranes using Fourier-transform infrared spectroscopy(FT-IR), field-emission scanning electron microscopy (FE-SEM), and differentialscanning calorimetry (DSC) confirmed the formation and uniform coverage of PPyon the cellulose surface. To enhance the uniformity of PPy polymerization oncellulose relative to previous studies, this work focuses on elucidating the formationand deposition of PPy particles on cellulose fibers, leading to the development of ahomogeneous membrane. The membrane exhibited a peak electrical conductivity of18.04 mS/cm at 0.1 mA, with conductivity increasing alongside PPy concentration,albeit at the expense of mechanical properties. Additionally, the membranedemonstrated charge storage capability, with specific capacitance values rangingfrom 22.5 to 50 pF/cm2 at a frequency of 1 kHz. The uniformity of PPy coverage onthe cellulose surface was a crucial factor influencing the electrical properties of thecomposite membrane. This research highlights the significant potential of conductivemembranes for application in flexible and bendable energy storage devices.The development of flexible electronic devices, particularly flexible andbendable energy storage devices, has catalyzed significant interest in the research offlexible composite materials.
