Melt Electrospinning Designs for Nanofiber Fabrication for Different Applications

Nanofibers have been attracting growing attention owing to their outstanding physicochemical and structural properties as well as diverse and intriguing applications. Electrospinning has been known as a simple, flexible, and multipurpose technique for the fabrication of submicro scale fibers. Throughout the last two decades, numerous investigations have focused on the employment of electrospinning techniques to improve the characteristics of fabricated fibers. This review highlights the state of the art of melt electrospinning and clarifies the major categories based on multitemperature control, gas assist, laser melt, coaxial, and needleless designs. In addition, we represent the effect of melt electrospinning process parameters on the properties of produced fibers. Finally, this review summarizes the challenges and obstacles connected to the melt electrospinning technique.

The present work was aimed at studying the effects of process parameters on morphologies of Polyvinyl alcohol (PVA) nanofibers in a novel electrospinning technique, bubble electrospinning. The process was optimized by constructing L 9(34) orthogonal experimental array design. Three factors were investigated and nine tests were run under lower, medium and higher levels of these factors. The results showed that PVA solution concentration plays an important role in affecting the morphologies of PVA nanofibers in bubble electrospinning process. With the increase of the concentration of PVA solution, the morphologies of fibers were changed from beaded fibers to uniform cylinder fibers and the average nanofiber diameter also increased. The optimization process was 12w% for PVA solution, 30kV for applied voltage and 10cm for spinning distance.

Electrospinning process is proved to be one of the finest fabrication techniques to produce nanofibers. This research deals with the experimental study on the effect of various process parameters of electrospinning technique such as voltage, flow rate, distance (nozzle to collector distance) and concentration, on the development of nanofibers from a new polymer, namely PBAT. Taguchis experimental design was implemented to carry out this research by conducting an L-18 orthogonal array. Taguchi method and Analysis of Variance (ANOVA) were employed to examine the effect of different process parameters simultaneously on the fabrication of nanofibers. The fibers were characterized through scanning electron microscope (SEM) for the measurement of its diameter. The experimental results indicate that all the chosen process parameters had significant influence on the fiber diameter. It was inferred that the concentration and voltage had a very notable impact on the fiber diameter. Confirmation experimental run was performed on the identified optimal setting of the process parameters.

Various authors have emphasized the spatial information resident in an electron micrograph taken with adequately coherent radiation. In view of the completion of at least one such instrument, this opportunity is taken to summarize the state of the art of processing such micrographs. We use the usual symbols for the aberration coefficients, and supplement these with £ and 6 for the transverse coherence length and the fractional energy spread respectively. He also assume a weak, biologically interesting sample, with principal interest lying in the molecular skeleton remaining after obvious hydrogen loss and other radiation damage has occurred.
