摘 要:
采用高压静电纺丝技术，以N，N-二甲基乙酰胺（DMAc）／异丙醇为混合溶剂，制备了聚乙烯-乙烯醇（EVOH）／碳纳米管（CNTS）无纺布膜．通过扫描电子显微镜及X射线衍射对其微观形貌及结晶行为进行了表征．结果表明，聚乙烯-乙烯醇／碳纳米管无纺布膜纤维的直径主要分布在80～200nm之间，纤维较细且分布较窄；电纺工艺以及碳纳米管的掺入均没有破坏聚乙烯-乙烯醇的结晶性。[著者文摘]

Abstract:
Poly （ ethylene - co - vinyl alcohol）/carbon nano - tubes （EVOH/CNTS） non - woven membranes are prepared by electrospinning technology with the solvent of N, N - dimethyl acetamide and isopropanel. The morphology of electrospun EVOIL/CNTS membranes were characterized by scanning electron microscopy （SEM）, and the crystallinity of electrospun EVOH/CNTS membranes were characterized by X- ray diffraction （XRD）. Results show that the fiber diameter in EVOH/CNTS non -woven membranes varied between 80 -200nm and the fiber diameter distribution was narrow. In addition, the crystallinity of EVOH/CNTS non - woven membranes is developed in case of casting membranes.[著者文摘]
