Schiff堿基過渡金屬聚合物電聚合環(huán)境調(diào)控及儲能機(jī)理研究摘要：

Schiff堿基過渡金屬聚合物是一類具有良好電導(dǎo)性的有機(jī)半導(dǎo)體材料，其在超級電容器、鋰離子電池等領(lǐng)域應(yīng)用廣泛。然而，其電化學(xué)穩(wěn)定性較差、循環(huán)穩(wěn)定性差、發(fā)生溶液聚合等問題限制了其進(jìn)一步應(yīng)用。因此，本文旨在通過環(huán)境調(diào)控及儲能機(jī)理研究來解決這些問題。首先，通過改變催化劑種類和控制催化劑濃度來優(yōu)化反應(yīng)條件，提高Schiff堿基過渡金屬聚合物合成的效率和純度；其次，通過添加不同含氧官能團(tuán)的溶劑和控制反應(yīng)溫度來解決溶液聚合問題，降低溶液中目標(biāo)產(chǎn)物的不純度和雜質(zhì)催化產(chǎn)物的形成；最后，通過使用X射線光電子能譜、循環(huán)伏安法、電化學(xué)阻抗譜等手段對Schiff堿基過渡金屬聚合物電化學(xué)性質(zhì)進(jìn)行分析，探索其儲能機(jī)理，并提出了改善其電化學(xué)性能的建議。該研究為Schiff堿基過渡金屬聚合物的應(yīng)用提供了理論和實(shí)踐基礎(chǔ)。
