The technical process that pulling method prepares nanofiber is similar to traditionally dry spinning process, can obtain single nanometer
Long fibre.But the subject matter of this method is that only viscoelastic material is only possible to be drawn into nanofiber, is greatly limited
Its application.
Templated synthesis represents a kind of method for directly preparing nanofiber, and it is to utilize the various moulds with one-dimensional pattern
Plate guides the formation of nanofiber, obtains the surface topography nano material complementary with template.Templated synthesis is a kind of simpler
Single, efficient, inexpensive method, but easily the nanofibrous structures formed are caused brokenly during template is removed
It is bad, and technical process is more complicated.
Self-assembling method refers to the construction units such as molecule and nano particle in equilibrium conditions, by non-covalent bond effect certainly
Hair ground be combined into thermodynamically stablize, determination in structure, aggregation process special in performance.Self assembling process is once general
Automatically some construction unit such as expected terminal, molecule is proceeded to by auto arrangement into patterns such as nanofibers, but it is this
Method needs longer time and yield very little.
Sea-island-type composite spun technology is that two kinds of heterogeneities are obtained into islands-in-sea type fibre by spinning, in this fiber
A kind of component is that " sea " another kind is " island ".Both components are continuous intensive, equally distributed upwards in fiber axis, if will
The composition in " sea " removes and has just obtained superfine fibre.But fibre diameter prepared by this method is all in more than 1000nm.
There is various deficiencies for the above-mentioned method for preparing nanofiber, it is desirable to provide a kind of effectively to prepare nanofiber
Method, this method have significantly advantage compared with other method.
