实验结果表明，以N-甲基吡咯烷酮作为制备溶剂，生成的膜材料中碳纳米管分布更加均匀，“更透气”，有效提升了膜材料气体分离效能和速率。
According to experiment results, if N-Methyl pyrrolidone is used as the fabrication solvent, the distribution of carbon nanotube in the membrane material produced is more even, making it more breathable, which effectively improves the membrane material’s gas separation performance and speed.
