“…All of these growth modes strongly depend on catalyst and reactive gas compositions. [16]; (b) bidirectionally grown twisted carbon filaments (b-TCFs) [17]; (c) tip grown single helical carbon filaments (t-SHCFs) [18]; and (d) tip grown twisted carbon filaments (t-TCFs) [18].

“…Figure 1 illustrates the different varieties of coiled carbon filaments that have been synthesized over the years. Based on growth mode, coiled carbon filaments can be classified into three groups: (1) bidirectionally grown double helical carbon filaments (b-DHCFs) [16]; (2) bidirectionally grown twisted carbon filaments (b-TCFs) [17]; and (3) tip grown single helical carbon filaments (t-SHCFs) [18] or tip grown twisted carbon filaments (t-TCFs) [18]. Structurally, some t-SHCFs and t-TCFs can have hollow cores like multi-walled carbon nanotubes (MWCNTs) [19].…”

“…In recent years, carbon materials have attracted considerable attention because of their novel morphologies and specially physical and chemical properties, such as fullerenes, 6 hollow and solid spheres, [7][8][9][10][11][12][13] nanotubes, [14][15][16][17][18] onions, [19][20][21] nanorods and nanocoils. 22 Among these, carbon spheres are becoming increasingly important due to their promising applications in the fields of medicine, pharmaceutics, material science and paint industry.…”

“…The CNR has a shape with multistrings twisted together. The HCNF has been synthesized and studied since the 1970s [4][5][6][7][8][9][10][11][12][13][14][15]. The CNC and CNTw relatively have good reproducibility, but CNR has been seldom seen.…”

“…So far, various catalysts have been tried. For example, for CNC, Ni [4], Fe-ITO [8], Cu-(Ni, Cr, Ti or Zn) [9], Au [10], Fe-SnO 2 [11,12], and Febased alloys (Fe-Cr-Mn-Mo, Fe-Cr-Ni-Mo (SUS513)) [13] have been tried, while for CNTw, Ni [4], Ni-Cu [3], Cu [14], and Fe-based alloys (Fe-Ni-Cr-Mo-Mn-Sn) [15] have been used. Compared with CNC, the CNTw has been able to be prepared in almost 100% purity with high uniformity of fiber diameter and shape [3].…”
