利用LB(Langmuir-Blodgett)方法组装C60复合膜,以二十二酸(BA)、二十酸(AA)、十八酸(SA)和十八胺(OA)作为辅助成膜材料,改变辅助成膜材料的摩尔比,成功地控制了C60的聚集结构.Dynamicforcemi-croscopy(DFM)形貌结果表明由摩尔比nC60∶nSA∶nAA∶nOA=2∶3∶3∶4组成的特定C60组装体具有两种结构∶一种为粒径大约180nm左右的大颗粒,另一种结构是粒径大约在30nm左右的小团簇.等链长的酸胺混合以及其它比例组成的C60聚集体颗粒大小不均且结构单一.UV-Vis吸收光谱也说明C60分子在LB膜中通过相互作用发生一定程度的聚集.
The C60 composite membrane was assembled by LB (Langmuir-Blodgett) method and its content was changed with the aid of behenic acid (BA), arachidic acid (AA), octadecanoic acid (SA) and octadecylamine (OA) The film-forming material molar ratio successfully controlled the aggregation structure of C60.Dynamicforcemi-croscopy (DFM) topography results show that the specific C60 assembly consisting of molar ratios nC60: nSA: nAA: nOA = 2: 3: 3: 4 Has two structures: one is a large particle with a size of about 180 nm, and the other is a small size with a particle size of about 30 nm, etc .. Equal chain length acid amine mixture and other proportions of C60 aggregate particle size Uneven and a single structure. UV-Vis absorption spectra also show that C60 molecules in the LB film through a certain degree of aggregation occurred.
