采用放电等离子烧结法对氟化碳纳米管进行脱附，制备了多壁碳纳米管固体。为了研究多壁碳纳米管的结构对所得固体的机械强度的影响，本实验中使用的多壁碳纳米管是用硝酸改性的缺陷多壁碳纳米管，并作为比较的纯化的非缺陷的纳米管。所得固体的弯曲强度和模量低于衍生自纯化MWCNT的脱氟MWCNT固体的那些。发现所得MWCNT固体的机械性质强烈依赖于MWCNT的结构。
We prepared and characterized multi-walled carbon nanotube (MWCNT) solids by de-fluorination of fluorinated MWCNTs using spark plasma sintering. In order to investigate the influence of the structure of MWCNT on the mechanical strength of the resulting solids, MWCNTs used in this experiment were as-defected MWCNTs modified by nitric acid and as-purified ones as non-defected nanotubes by comparison. The bend strength and modulus of the resulting solids were lower than those of de-fluorinated MWCNT solids derived from as-purified MWCNTs. The mechanical properties of the resulting MWCNT solids were found to be strongly dependent on the structure of the MWCNT.
