摘要

分别采用水热法和化学气相沉积（CVD）法，制备两种同粒径（约360 nm）的碳微球（CMSs），对CVD法制备的CMSs （CCMSs）用混酸溶液（浓硫酸：浓硝酸=3：1）进行酸化处理，在其表面引入含氧官能团，而水热法制备的CMSs（HCMSs）不作处理；然后在N，N'-二环己基碳二亚胺的作用下，用1，6-己二胺分别修饰两种CMSs。通过场发射扫描电子显微镜和傅里叶红外光谱仪对产物的形貌和结构进行表征分析，采用热重分析仪和电化学工作站对产物的热稳定性和能级结构进行表征分析，并用荧光分析仪对产物的光学性能进行表征分析。结果表明：两种CMSs都满足作为聚合物太阳能电池受体材料的能级要求，且胺化修饰可以提高CMSs的LUMO能级；HCMSs在形貌、溶剂中的分散性以及热稳定性等方面都优于CCMSs，比CCMSs更适合作聚合物太阳能电池的受体材料。

Abstract

Two kinds of carbon microspheres (CMSs) were prepared by the hydrothermal method and chemical vapor deposition (CVD)

the CMSs prepared by CVD (CCMSs) were oxidized by a mixture of concentrated sulfuric acid and nitric acid (volume ratio of 3:1) to improve their surface activity

while the CMSs prepared by the hydrothermal method (HCMSs) were used as obtained. Then

two kinds of CMSs reacted with1

6-hexanediamine to prepare aminated CMSs with N

N'-dicyclohexyl carbodiimide as condensation agent. The morphology and structure of products were characterized with field emission scanning electron microscopy and Fourier transform infrared spectrometry. The thermostability and energy level structure were characterized with thermogravimetry and electrochemical analysis

the optical properties were characterized with fluorescence analysis. Both CMSs met the requirement of energy level as receptor materials in polymer solar cell

and amination increased the LUMO energy level of CMSs. HCMSs was superior to CCMSs in morphology

dispersibility in solvents and thermal stability

so HCMSs could be more suitable for using as the receptor materials of polymer solar cell.
