investigated the influence of the polymer solution concentration, the diameter of the electrospinning needle and the electrospinning time of uniaxial PLA/PCL fibers on the fiber diameter and elongation using a central composite design [22]. Rivero et al. applied the central composite DoE approach to...

Coaxial electrohydrodynamic jet (CE-Jet) printing is an encouraging method for fabrication of high-resolution micro and nanostructures in MEMS systems. This paper presents a novel simulation work based on phase field method which is considered as a preci
The core–shell or coaxial nozzle is a concentric set of coaxial spinnerets composed of an outer and inner needle, as illustrated in Fig. 8.3A and B. Coaxial electrospinning can generate fibers from various solution pairs, such as, core-sheath, hollow, and functional fibers that may contain ...
Coaxial electrospinning is a modification of the conventional electrospinning process (Díaz et al., 2008) involving the arrangement of multiple solution feed systems to simultaneously electrospin two or more polymer solutions from coaxial capillaries. From: Electrospun Nanofibers, 2017 ...
Moreover, a natural polymer, gelatin, has been chosen as the shell by using coaxial core-shell electrospinning to obtain favorable proliferation and cell adhesion. Finally, structure and morphology of electrospun samples were characterized using scanning electron microscopy (SEM) and transmission electron...
The as-obtained polymer solution was electrospun with a 21-gauge needle in the following conditions: Material characterization The synthesis process of hollow core-shell structured CNT/PAN@Co9S8@C coaxial nanocables is schematically shown in Fig. 1. Firstly, electrospinning CNT/PAN nanofibers were...
the distance from the needle to the roller was 12 cm; and the speed of the roller was 400 r min−1. After coaxial electrospinning, the sample was subjected to heat treatment to obtain the CoS1.097@C core–shell fibers. The heat treatment included two stages. The first was pre-oxidation...
