使用透射电子显微镜 (TEM) 和 TEM 图像的分形维分析，研究了紫外线 (UV) 诱导的化学键形成对聚 (4-氯甲基)苯乙烯/MWCNT 复合材料中多壁碳纳米管 (MWCNT) 分散/聚集状态及其电导率的影响。与未辐照复合材料相比，用紫外线辐照制备的复合材料表现出较低的电导率和捕获的多壁碳纳米管的更密集的聚集。 TEM 图像的分形维数分析表明，与电导率相关的分散/聚集状态的差异可能与盒计数法计算的分形维数相关。
The effects of ultraviolet (UV)-induced chemical bond formation on the dispersion/aggregation state of multi-walled carbon nanotubes (MWCNTs) in poly(4-chloromethyl)styrene/MWCNT composites and their electrical conductivity were examined using transmission electron microscopy (TEM) and fractal dimensional analysis of the TEM images. The composites prepared with UV irradiation exhibited lower electrical conductivity and denser aggregation of the trapped MWCNTs than those observed for unirradiated composites. Fractal dimensional analysis of the TEM images indicated that the difference in the dispersion/aggregation state associated with electrical conductivity could be correlated to the fractal dimension calculated by the box-counting method.
