Summary

Nanoscale fluid mechanics plays an important role in nanomaterial fabrication in electrospinning and 3-D printing technology. This special issue focuses on the spinning, printing or writing process in a view of nanoscale flow to control nanoparticles or molecules’ distribution and orientation in the fabricated objects. Nature-inspired fabrication technologies are specially emphasized.

Needleless Electrospinning: Reciprocation vs. Rotation
Xiaoxia Li, Manyu Qian, Dan Tian, Jihuan He
FDMP-Fluid Dynamics & Materials Processing, Vol.17, No.6, pp. 1015-1019, 2021, DOI:10.32604/fdmp.2021.015430

Abstract Needleless electrospinning is a versatile method to produce nanofibers. In particular, the rotary version of this technique has enjoyed widespread use because there is no need to clean the spinneret. The rotation speed is limited by the potential deviation of the jet due to the centrifugal force. Other limitations are due to the fast volatilization of the solvent from the opened spinning system. In order to overcome these drawbacks, here a novel reciprocating system based on a moving spinning-plate is proposed. The spinning process is implemented in a half-closed system with the spinning-plate immersed in the solution tank. When the… More >

Abstract In the search for sustainable alternatives to harmful synthetic fibers, an increasing amount of research focuses on biomimicry and natural fibers. Sea silk is an exceptional textile material. It is a kind of natural silk produced using the long silky filaments secreted by a specific bivalve mollusk (Pinna nobilis); now at edge of extinction. This paper suggests a simple but effective way to prepare artificial sea silk from Mytilus edulis. A sea silk solution is prepared using a Mytilus edulis protein, and a polyvinyl alcohol (PVA) solution is mixed with the sea silk solution in order to produce artificial sea… More >

Preparation and Characterization of Electrospun Polylactic Acid Micro/Nanofibers under Different Solvent Conditions
Hao Dou, Hongxia Liu, Feng Wang, Yanli Sun
FDMP-Fluid Dynamics & Materials Processing, Vol.17, No.3, pp. 629-638, 2021, DOI:10.32604/fdmp.2021.015612

Abstract Electrospinning is a versatile and popular method for the fabrication of ultrafine fibers and many parameters in electrospinning can be adjusted when ideal micro/nanofibers are required. In particular, the selection of a proper solvent condition is a fundamental and crucial step to produce electrospun ultrafine fibers. In this study, a commonly used biomaterial, polylactic acid (PLA), was dissolved in 7 different solvents and PLA micro/nanofibers were prepared by electrospinning. The morphology, porosity, mechanical property and static contact angle were characterized to determine the quality of the obtained product. The results show that different solvent conditions have a significant effect on… More >
