碳纳米管吸附的电纺PA66纤维束

Carbon Nanotube Adsorbed Electrospun PA66 Fiber Bundles

采用超声的方法将多壁碳纳米管（MWNTs）超声到静电纺丝聚酰胺66（PA66）纤维上。通过扫描电子显微镜（SEM）、力学性能测试以及万用电阻表来表征超声前后纤维束的形貌、力学性能以及超声处理后纤维束的电阻。结果表明,经超声处理后MWNTs均匀地附着在纤维表面,纤维束的强度及韧性均有明显的提高,纤维束的电阻分布在150~230 kΩ,极优的导电性表明MWNTs在纤维表面分布均匀,这同时也说明碳管与PA66纤维之间具有较强的界面相互作用。

Multi-wall carbon nanotubes （MWNTs） were adsorbed onto eleetrospun PA66 fibers through sonication. Scanning Electron Microscopy （SEM）, tensile test and u- niversal resistance meter were used respectively to characterize the morphology, mechanical properties and resistivity of the fiber bundles after ultrasound in MWNTs solution. Results show that MWNTs disperse outside PA66 fibers evenly. The tensile strength and toughness are both increased and the resistivity of bundles distributes in 150-230 kΩ. The excellent electrical conductivity further proves the homogeneous distribution of MWNTs, which means a strong interaction between MWNTs and PA66.
