纺制纳米纤维的方法有很多,利用离心力、毛细管力、电场力、拉伸力、吹塑、熔融和蒸发等方法,这些制作方法各有利弊,而且都需要繁重的设备和一定的室内条件。近日,哈佛大学研究人员开发出了一种轻巧便携的纳米纤维纺丝装置,并将这项研究在《Macromolec-ular Materials and Engineering》上发表。这种便携式纳米纺丝设备生产效率高,而且可以精确控制取向。研究者们通过调整纤维取向和沉积方式,建造纳米纤维支架。这种支架可以模拟身体里高度定向的组

There are many ways of spinning nanofibers. These methods have their own advantages and disadvantages, such as centrifugal force, capillary force, electric field force, tensile force, blow molding, melting and evaporation, etc., and require heavy equipment and certain indoor conditions. Recently, Harvard researchers have developed a lightweight and portable nanofiber spinning device, and the study published in “Macromolecules”. This portable nano-spinning equipment is highly productive and can precisely control the orientation. Researchers build nanofiber scaffolds by adjusting fiber orientation and deposition.
