With the optimum parameter, the obtained composite particle have many changes compared with uncoated graphite, such as the increase of coating ratio, particle size and decrease of specific surface area, et al
在最佳包覆工藝條件下,所得復合粉體相對未處理石墨氧化物含量(包覆率)增加、粒度增大與表面積減小。By the analysis of coating ratio, oxidation ratio, micrograph and particle size of composite particle, it was found out that factors such as ph value, coating temperature, concentration of premonitory matter solution mainly affect the coating layer forming
通過包覆率、氧化失重率、形貌觀察、粒度和比表面積等分析發現,非均勻成核過程中溶液ph值、包覆溫度、覆層前驅物濃度等這幾個因素對石墨表面覆層形成有著重要影響。At lower growth temperature, the lower extracting rate of carbon atoms from catalyst particles due to the lower activity of the catalysts resulted in more defects formed in carbon nanotubes. moreover, the lower transportation rate of carbon atoms in catalyst particles also made lots of carbon atoms deposited on the surfaces of grown carbon nanotubes, or on carbon wrapped catalyst particles, even to form amorphous carbon layers
在較低溫度時,由於催化劑的活性較低,導致石墨面在生長過程中引入的缺陷較多;另一方面,碳原子在催化劑顆粒內遷移速率較低,使得多餘的游離態碳原子(或原子團)可能在納米碳管表面以非晶形式沉積,或者包覆催化劑使其「中毒」失去催化活性,或者直接形成非晶的碳納米顆粒。
