🔋 Morphology and Ion Transport in Zwitterionic Polysiloxanes

📝 رسانایی یونی ابریونی در پلی‌زویتریون‌های دوپ‌شده جهانی نیست و نیازمند کانال‌های یونی پرکولاسیون است؛ در پلی‌سیلوکسان زویتریونی با LiTFSI، نانودومین‌های مجزا تحرک یون را محدود می‌کنند.

💡 Novelty & Significance:
This study challenges the assumption that superionic conductivity is universal in doped polyzwitterions, showing it requires percolating ion channels. Using polysiloxane-based PZI with LiTFSI, isolated zwitterionic nanodomains limited conductivity to ~10⁻⁸ S/cm; overlap of these clusters enabled significant enhancement. The findings establish morphological control of ion-transport pathways as critical for designing superionic polymer electrolytes.
