以石墨为基体,硫酸镍为催化剂,利用化学气相沉积通过松节油的催化分解合成了微米炭纤维.利用酸处理和水洗的方法将纤维从石墨和金属杂质中分离出来.利用光学显微镜和扫描电镜发现得到的纤维直径在3 μm～5μm.同时,由于自组装的作用也生成了一些海绵状的微米纤维.

Carbon microfibers were synthesized by chemical vapor deposition during the decomposition of turpentine oil in the presence of nickel sulfate as a catalyst precursor on a graphite host.The fibers were separated from graphite and metal impurities by acid treatment,followed by several washes with deionized water.These fibers have a diameter of approximately 3-5 μm and they were studied by optical and scanning electron microscopy.A sponge-like morphology of the microfibers due to self-assembly was observed.
