Research advances in electrospinning collectors for preparation of nanofibers

Electrospinning is an important method to fabricate nanofibers that has strong application value in many fields and has caused widespread concern. Due to the orientation and structure of nanofibers having great influence on its performance, recent researches focused on how to get electrospun material with different structure or morphology to meet the requirement of different areas. As an important part of electrospinning apparatus, the collectors determine the distribution and combination of electrospun fibers. Three basic types of electrospun materials can be fabricated through the improvement of collectors at present, namely aligned nanofibers, patterned fiber membranes and three-dimensional structures. This paper briefly describes electrospinning principle, respectively, compares the structural characteristics and receiving effect of different collectors may be employed in the preparation of three types of electrospun materials. This review will be useful for reference of studies about the preparation of nanofiber materials, design of electrospinning devices and application of electrospinning technology.
