“…The process of coagulation of spinning solution follows the well-known principle of phase separation in the polymer solution. 27 After sufficient interaction (residence) time, the electrospun strand became the solid, as-spun filament. Electrospun porous filaments were produced using distilled water or distilled water/methanol as the coagulating liquid.…”

Electric field-driven fiber formation (electrospinning) is developing into a practical means for preparing novel porous filament with unusual structures and affordable mechanical properties. Polycaprolactone (PCL) was dissolved in solvent mixtures of methylene chloride/N,N-dimethyl formamide with ratios of 100/0, 75/25, and 50/50 (v/v) for electrospinning. The filament was formed by coagulation of the spinning solution following the well-known principle of phase separation in polymer solutions valid in other wet shaping processes. A strand of electrospun porous filament consisted of fibers ranging from 0.5 to 12 m in diameter. To evaluate the feasibility of three-dimensional fabric as scaffold matrices, the plain weave, which is the simplest of the weaves and the most common, was prepared with porous PCL filament. The growth characteristics of MCF-7 mammary carcinoma cells in the woven fabrics showed the important role of matrix microstructure in proliferation. This study has shown that woven fabrics, consisting of porous filaments via electrospinning, may be suitable candidates as tissue engineering scaffolds.

“…[9,13] Furthermore, the jet is strongly elongated during electrospinning due to the acceleration in the direction of the counter electrode. The solidification will be controlled by the onset of a glass transition process as the concentration of the solvent is further reduced [26] or by the onset of crystallization. The evaporation of the solvent thus will happen on a time scale well below the second-range.…”

“…The density modulations that occur during this spinodal decomposition are "frozen in" during subsequent crystallization and affect the morphology of the resulting crystalline phase [80]. This phenomenon is, in fact, of considerable practical importance for the control of sol-gel transitions, in particular in the context of membrane formation [81][82][83].…”
