Abstract
Zwitterion-based polymer electrolyte membranes (PEMs) have emerged as promising next-generation materials owing to their superior water retention capability and enhanced ionic conductivity. In this work, crosslinked polymer electrolyte membranes were prepared via solution casting, where the membrane composition and crosslinking degree were systematically controlled to optimize water uptake and dimensional stability. The incorporation of zwitterionic moieties imparted strong hydrophilicity to the polymer matrix, effectively improving moisture retention and reinforcing continuous proton transport pathways throughout the membrane structure. Key processing conditions, including solvent composition, thermal treatment temperature, and relative humidity during membrane formation, were carefully adjusted to tailor the physicochemical and electrochemical characteristics of the resulting membranes. Surface wettability and morphological analyses confirmed well-developed phase-separated structures, indicative of interconnected hydrophilic ionic domains favorable for efficient ion transport. The resulting membranes are currently under electrochemical evaluation for proton conductivity and chemical stability using electrochemical impedance spectroscopy (EIS) and linear sweep voltammetry (LSV), with the aim of demonstrating their feasibility as high-performance polymer electrolyte materials for advanced electrochemical applications.
