利用强酸改性和超声分散技术使碳纳米管(CNTs)能有效分散在聚甲基丙烯酸甲酯(PMMA)纺丝液中,同时加入β-环糊精(β-CD),改善PMMA的亲水性,并且利用β-CD独特的内疏水外亲水又具有中空锥形结构与CNTs形成包含复合物,有利于CNTs在纺丝液中分散,通过静电纺丝制备PMMA/β-CD/CNTs功能性复合纳米纤维,然后对复合纳米纤维的表观形态、亲水性、抗静电等性能进行测试分析;结果表明:当纺丝液流量为0.3mL/h,所施加的电压为19kV,接收距离为16cm时能得到较均匀、重现性较好的复合纳米纤维;同时β-CD的加入能有效改善PMMA的亲水性,最后加入β-CD和CNTs后PMMA具备一定的抗静电性。
Carbon nanotubes (CNTs) can be efficiently dispersed in polymethylmethacrylate (PMMA) spinning solution by using strong acid modification and ultrasonic dispersion technology, while adding β-cyclodextrin (β-CD) to improve the affinity of PMMA Water-based, and the use of β-CD unique hydrophobic inner hydrophobic and hollow cone-shaped structure with the formation of CNTs containing complex, is conducive to the dispersion of CNTs in the spinning solution, prepared by electrospinning PMMA / β-CD / CNTs Functional composite nanofibers, and then the composite nanofibers apparent morphology, hydrophilicity, antistatic properties were tested and analyzed; the results show that: when the spinning solution flow rate of 0.3mL / h, the applied voltage of 19kV, receiving At a distance of 16 cm, a more uniform and reproducible composite nanofibers could be obtained. At the same time, the addition of β-CD could effectively improve the hydrophilicity of PMMA. Finally, the addition of β-CD and CNTs possessed certain antistatic properties.
