摘要

摘要: 采用Hummers法制备氧化石墨烯(GO),利用水热法对GO分别还原5 h和10 h制得两种还原氧化石墨烯(5-RGO和10-RGO),进一步用异氰酸苯酯对还原前后的氧化石墨烯材料进行改性,即得功能化氧化石墨烯和功能化还原氧化石墨烯(SPFGO、5-SPFRGO和10-SPFRGO)。以功能化还原氧化石墨烯材料为电子受体,聚3-己基噻吩(P3HT)为电子给体,制备复合膜。结果表明:GO由3-5层组成,经水热还原后样品表面仍含有—CO,—COOH等含氧官能团;功能化后石墨烯在邻二氯苯中分散性良好,与P3HT能级相匹配,满足作为聚合物太阳能电池受体材料要求;以5-SPFRGO做为受体材料与P3HT复合制备的复合膜表面规整致密,光吸收强度高,荧光光谱强度低,性能最优。

Abstract: Graphene oxide (GO) prepared by the Hummers method was hydrothermally reduced for 5 and 10 h to obtain 5-RGO and 10-RGO, respectively. The GO and RGOs reacted with phenyl isocyanate to obtain three solution-processable functionalized graphenes (SPFGO, 5-SPFRGO and 10-SPFRGO), which were used as electron acceptors to prepare composite films with poly 3-hexylthiophene (P3HT) as an electron donor in polymer solar cells. Results indicate that GO consists of about 3-5 layers, and the RGOs still have some oxygen-containing functional groups such as —COOH and CO after the reduction. Functionalized GOs have good dispersibility in dichlorobenzene and exhibit energy levels matching P3HT, indicating that they can be used as the electron acceptor materials of polymer solar cells. A5-SPFRGO/P3HT composite film exhibits good compatibility, strong light absorption and obvious fluorescence quenching, suggesting that 5-SPFRGO is an excellent electron acceptor material.
