摘　　要：The surface morphology of micro-and nano-scale fber determines its application to a great extent.At present,a variety of secondary morphology of microfbers and nanofbers,such as porous,wrinkle,groove and so on,have been prepared.Among them,grooved micro-and nano-fbers are attracting more and more attention because of their unique morphology and properties.In this paper,we review the literature on grooved fbers due to void-based elongation,wrinkle-based elongation,collapsed jet-based elongation and selective dissolution.By contrast,the method of phase separation is simpler and more commonly used than selective dissolution.What is more interesting is that the number and depth of grooves on the fber surface can be well controlled by adjusting the experimental parameters,which greatly increases the research value and application felds of grooves micro-nano fbers.Grooved fbers can be made from a range of materials:polycaprolactone(PCL),polylactic acid(PLA),polystyrene(PS),cellulose acetate butyrate(CAB)and other polymers.The applications of grooved micro-nano fbers are discussed in detail,including peripheral nerve regeneration,water manipulation and energy conversion.
