<p>➀ Researchers at Purdue University have developed a transparent conducting polymer, n-doped poly(benzodifurandione) (n-PBDF), which could revolutionize electrochromic displays by making them more sustainable and energy-efficient.</p><p>➁ The n-PBDF polymer acts as both a transparent conductor and an ion-storage material, simplifying device architecture and reducing power consumption.</p><p>➂ The team plans to improve film uniformity, expand compatibility with other electrochromic materials, and explore applications in batteries, solar cells, and organic LEDs.</p>
