The present paper investigated the preparation and characterization of electrospun polyacrylic acid resin IV nanofiber. The electrospinnability of polyacrylic acid resin IV in N, N-Dimethylacetamide (DMAc), ethanol, methanol, and the mixed solvents of DMAc and methanol with different ratios were examined. Scanning electron microscope (SEM) was carried out to observe the morphology of the nanofibers...
The electrospinning system mainly has vertical type and horizontal type according to the geometrical arrangements of ejecting capillary and collection target, where vertical type includes shaft type and converse type. The fibers were obtained in several kinds of typical electrospinning parameters by using three different electrospinning systems. The SEM was used to observe the morphology of fibers,...
In the present study, Eudragit L100 was successfully spun into ultrafine fibers using electrospinning process. The electrospinnability of Eudragit L100 in DMAc, ethanol, methanol, and the mixed solvents of DMAc and methanol with different ratios were examined. The morphologies of the as-spun Eudragit L100 fiber mats were observed using SEM. The results demonstrated that Eudragit L100 was able to be...
Electrospinning is a straightforward and effective technique to produce nanofiber nonwovens. In this paper, a comb ionomer of poly(ethylene covinyl alcohol) end-capped with sulfonic acid (EVOH-g-SO 3H) was synthesized by two-step synthesis process and electrospun into nonwoven membranes. The effect of processing parameters on the fibrous and beads morphology was investigated by scanning electron microscopy...
