Polymer electrolyte that quadruples triboelectric power generation efficiency is also durable

"ionic-liquid-based materials suffered leakage, environmental instability, poor durability, overcome using polymer electrolyte where ions are permanently anchored to polymer chains... precisely controls triboelectric materials' polarity... allows for triboelectric polarity (positive/negative) tuning by adjusting polymer structure... cationic polymer exhibited 83V output voltage, about 2X higher; anionic polymer achieved 34V, 4X higher than conventional... minimal charge loss/ excellent thermal stability for over week even at 60℃"
