However, transmission electron microscopy (TEM) reveals that the CNTs are indeed well admixed with [Cu3(btc)2]. The CNTs, which act as composite fillers in the microcrystal, can be seen from the TEM image at low magnification (Figure 1 a). High-resolution hybrid composite lattice images (Figure 1 b, c) also show two distinctive lattice spacings of 0.203 and 0.33 nm, which correspond to the
interlayer spacing values for the (10 8 2) plane of [Cu3(btc)2] and the (0 0 2) plane of the multiwalled CNTs, respectively.These results therefore indicate that the CNTs are incorpo-rated in [Cu3(btc)2]. It is assumed that the [Cu3(btc)2] crystals are formed by heteronucleation and crystal growth on the carboxylic groups of the CNT.[4a]
However, it is very difficult to characterize the interface region of CNTs in the frame-works by using available techniques.
这是文章中对这个表征的描述,看不太懂,各位帮帮忙呀,什么叫晶格间距,低倍的还看的懂,高倍的呢
