内容摘要:光电高分子材料的制备及其应用于聚合物太阳能电池、光降解及电催化等领域。

(一)在聚合物太阳能电池中, 主要有三个内容:

1. 嵌段聚合物的合成及其应用于杂化太阳能电池,对于高分子/无机量子点的形貌调控,实现了无机量子点在高分子材料中的高度有序可控分布。

2. 为聚合物太阳能电池的结构设计和制备,成功地将无机量子点阵列应用于聚合物太阳能电池中,结合液晶小分子对无机量子点阵列的界面调控和修饰,有效地提高了太阳能电池的电子迁移率,从而实现高效率太阳能电池的制备。

3. N-型共轭聚电解质的自掺杂的研究,发现P-型共轭聚电解质的自掺杂可实现高导电率的高分子材料,并可应用于热电中,而N-型共轭聚电解质的自掺杂可实现聚集态发光的效果。制得的N-型共轭聚电解质应用于单异质结聚合物太阳能电池时,其光电转换效率可达11%,性能接近于目前已有单异质结聚合物太阳能电池的最高光电转化效率。

(二)对于光电高分子材料的光降解,通过侧链和主链的设计来研究其对光电高分子材料的光降解速率的影响,研究为将来可降解塑料的设计开发做理论依据。

(三)高分子材料的电催化领域为未来主要研究方向。结合无机二维材料实现高效率的有机/无机复合材料的电催化效率。
