Electrospinning of native and anionic corn starch fibers with different amylose contents

Jet evolution and fiber formation mechanism of amylopectin rich starches in centrifugal spinning system

“…In order to fabricate the starch‐based fiber from native starches, researchers attempted to use the formic acid aqueous (88%) as solvent. They have been successfully fabricated starch‐based fibers from various starches with different amylopectin content such as Hylon VII cornstarch (amylopectin: 30%), Hylon V cornstarch (amylopectin: 45%), native cornstarch (amylopectin: 70%), soluble potato starch (amylopectin: 33%), and even amylopectin 13–15 . Nevertheless, the limitations of productivity and high voltage for electrospinning, and the strong corrosive of formic acid seriously affected the largely industry production of starch‐based fibers 16 .…”

[13][14][15] Nevertheless, the limitations of productivity and high voltage for electrospinning, and the strong corrosive of formic acid seriously affected the largely industry production of starch-based fibers. 16 In the previous studies, we successfully fabricated centrifugally spun starch-based fibers from amylopectin rich native starches by using 2.0%(wt/wt) aqueous sodium hydroxide solution as solvent, and the starches with amylopectin ratio high as 81% were demonstrated suitable for fiber fabrication.…”

Production and Optimization of Ultrafine Fiber from Yam Starch by Electrospinning Method Using Multivariate Analysis

“…[ 13 ] Due to its linearity, amylose can be readily electrospun into fibers. [ 8 ] According to Fonseca et al., [ 2 ] the amylose content of starch has a direct influence on the quality of fibers produced by electrospinning. In their study, it has been found that fibers produced with high amylose corn starch (55% and 72%) in their native and anionic form were more continuous, uniform and with less beads when compared to starch with normal amylose content (29.7%).…”

“…Univariate studies on the optimization of electrospinning conditions have been reported in the literature for the production of native and anionic corn starch fibers, using the parameters of process voltage (kV) and flow of the polymeric solution (mL h −1 ). [ 2 ] Multivariate study to optimize the production of fibers by electrospinning was also reported by Gee et al., [ 17 ] who optimized the electrospinning process using poly(vinylidene fluoride) and evaluated an interference of four measures in the formation of fibers: solvent ratio (dimethylformamide/acetone), tip‐to‐collector distance, polymer solution flow rate, and applied voltage. However, multivariate designs using native yam starch as a polymeric material for electrospinning have not been reported to date.…”

“…[ 1 ] Electrospun nanofibers can be obtained from synthetic or natural polymers, or even a blend of both. [ 2 ] Several biopolymers have been proposed as a polymer material for the production of fibers, including gelatin, zein, pullulan, cyclodextrin, cellulose, chitosan, alginate, dextran, native, soluble, and anionic starches.
