原位构建纳米结构的方法是纳米技术的关键工具。在此，针对两种纳米材料的强制结合，探索了一种“反荷喷嘴电液动力喷射（EJC）”的原位结合技术。EJC利用电流体动力旋转和喷涂产生的表面负电荷和正电荷之间的吸引力。所获得的纳米结构取决于材料类型和喷射条件。将聚甲基丙烯酸甲酯纳米或微纤维与聚苯乙烯纳米或微颗粒均匀结合。用硫辛酸（一种抗氧化药物）代替聚苯乙烯，得到了纤维和表面纳米点的复合结构。这种方法还可以使金纳米颗粒粘在纤维表面。EJC是一种利用具有广泛性能的材料制造复合纳米结构的有效技术。
Methods toin-situconstruct nanostructures are the key tools of nanotechnology. Herein, for the enforced combination of two nanomaterials, anin-situcombination technique, ‘electrohydrodynamic jetting of countercharged nozzles (EJC)’, was explored. EJC used an attraction force between negative and positive surface charges generated by electrohydrodynamic spinning and spraying. The obtained nanostructures were dependent on the types of materials and jetting conditions. Poly(methyl methacrylate) nano- or micro-fibers were uniformly combined with polystyrene nano- or microparticles. When lipoic acid (an antioxidant drug) was used instead of polystyrene, composite structures of fibers and surface nanodots resulted. The method could also enforce gold nanoparticles stick onto the surface of fibers. EJC is an efficient technique to fabricate composite nanostructures using materials with a wide range of properties.
