The electro spinning process is of great utility in the manufacture of non-woven fabrics for a variety of applications including tissue engineering. A machine has been constructed capable of electrostatically spinning (electro spinning) a wide range of.

ELECTROSPINNING OF NANOFIBERS AND THEIR APPLICATIONS. Electrospinning is a useful and efficient technique to produce ultrafine polymeric fibers. It has been a process of great scientific and industrial interest due to its versatility, cost-efficiency and potential to be used in a wide range of applications, resulting in an outstanding potential for nanotechnology research. As it is regarded.

A Study of the Effects of Solution and Process Parameters.

The electrospinning technique provides non-wovens to the order of few nanometers with large surface areas, ease of functionalisation for various purposes and superior mechanical properties. Also.Electrospinning, a method of making nanofiber mats from solutions of an active pharmaceutical ingredient (API), polymer and solvent, has shown great promise for producing final solid dosage forms with minimal process steps. In this thesis, we explore the use of electrospinning to produce fiber mats containing either amorphous or crystalline API, aiming to develop the process such that it can.Brown, Toby David (2015) Melt electrospinning writing. PhD by Publication, Queensland University of Technology. Preview. Toby Brown Thesis (PDF 11MB) Description This thesis has developed an innovative additive manufacturing technology platform, which combines melt electrospinning with direct writing, allowing the fabrication of a new class of highly-ordered ultrafine fibrous materials.


Furthermore, an optimum electrospinning voltage at which the maximum degree of crystallinity can be obtained was observed. Finally, bi-component scaffolds based on PLLA and gelatin were electrospun. Multicomponent scaffolds based on PLLA, gelatin and hydroxyapatite (HA) were electrospun followed by electrospraying of the HA phase. Blending gelatin with PLLA resulted in an approximate 50%.Electrospinning process is a very complex process and is associated with the interaction of several physical instability processes. According to Reneker and Chun, the stable electrospinning jet is composed of four regions: the base, the jet, the splay, and the collection. In the base region, the jet emerges from the needle to form a cone known.

The thesis addresses two different but related topics. The first topic is improvement of the water vapour barrier properties of PLA films. The effect of montmorillonite clay and its alignment on water vapour permeability and the effect of crystallinity (introduced by annealing) on nanoclay alignment and barrier properties were investigated (Chapter 4). PLA nanocomposites containing 0 to 5 wt.

The specific removal of molecules from various media is an area receiving increasing attention. Affnity membranes, i.e. membranes containing ligands, which can specifically capture target molecules, can meet this demand. One important area, in which the use of affinity membranes will be beneficial, is blood filtration, specifically haemodialysis treatments.

Electrospinning or electrostatic fibre spinning employs electrostatic force to draw fibres from a liquid, either a polymeric solution or a polymer melt in the form of a charged jet. The jet solidifies and is deposited on a collector in the form of a non-woven fibrous mat. Electrospun fibres have diameters between several nanometres to a few microns, which is one of the main advantages of the.

Electrospinning is a fiber production method which uses electric force to draw charged threads of polymer solutions or polymer melts up to fiber diameters in the order of some hundred nanometers. Electrospinning shares characteristics of both electrospraying and conventional solution dry spinning of fibers. The process does not require the use of coagulation chemistry or high temperatures to.
