摘　　要：为进一步深入研究静电纺丝技术及Janus微纳米纤维的可控制备,使具有非均质结构特点的Janus纤维材料在多功能复合材料领域得到更广泛的应用。近年来,随着静电纺丝技术的不断发展,Janus纤维的纺制工艺逐渐从纺丝装置拓展、纺丝参数优化以提高纤维并行率,逐渐向纤维形貌多样化、结构多级化及组成多相化的导向性设计方向发展,以推动Janus纤维在多功能复合材料领域的快速发展。本文综述了基于静电纺丝技术所制备的并轴及同轴结构的Janus微纳米纤维,比较说明了不同结构Janus微纳米纤维的制备方法、形成机制及结构调控等方面的研究进展及成果,并进一步表明了静电纺丝技术在实现Janus纤维微纳米尺度导向性结构控制方面具有广泛的应用潜力。In order to further study the electrospinning technology and the controllable preparation of Janus micro/nano fibers,Janus fibers materials with heterogeneous structure characteristics have been more widely used in the field of multi-functional materials.In recent years,with the continuous development of electrospinning technology,the spinning process of Janus fiber has gradually expanded from spinning device,spinning parameter optimization to improve fiber parallelism rate,and gradually developed to the guided design direction of fiber morphology diver-sification,structure multiphase and composition multiphase,in order to promote the rapid development of Janus fiber in the field of multi-functional materials.In this paper,the co-axial and coaxial-structure Janus micro/nano fibers prepared by electrospinning technology and other fiber structures derived from them are reviewed.The research progress and achievements in the preparation methods,formation mechanism and structural regulation of Janus fibers with different morphologies and structures are compared.It is further demonstrated that electro-spinning technology has wide application potential in realizing micro-and nano-scale oriented structure control ofJanusfibers.
