Melt electrospun PLA sub-micron fibre mats with no residual solvent can be employed as filter media and tissue scaffolds preferred to those prepared by solution electrospinning processes, due to the elimination of possible... 

Timely recent developments in melt electrospinning make it possible to potentially fabricate fibrous webs and networks with precise fibre diameters and patterning and thus provide fibrous architectures for cell integration and re-assembly into organized tissue. Our innovative approach is to use polysaccharides in the fibre composition to deliver useful encapsulates and form better biological associations than currently used polymers. We therefore propose to use melt electrospun...

Kim and Lee 2000 investigated the thermal properties of electrospun PET and PEN fibers made from melts (Kim and Lee 2000). 

Recent studies have indicated direct correlations between surface area and catalytic activity of metal oxide sensors (Li et al. 1999). Therefore, it is evident that incorporating catalytic particles by coating techniques may affect surface area and catalysis. Studies by Lee and Bhat (2003) have demonstrated that by incorporating small amounts of electrospun nanoflbers in spun-bond and melt-blown nonwovens, barrier properties such as flitration efficiency and air permeability can be improved. 

Nanofibre mats are produced by the electrospinning process as a result of the potential gradient between needle tip and collector. Various polymers have been successfully electrospun into ultrafine fibres mostly from solvent solution and some in melt form... 

Electrospinning is an efficient technique for the fabrication of polymer fibers. Various cationic polymers have been successfully electrospun into ultrafine fibers, mostly from solvent solutions but some in melt form. Composite nanofibers of biodegradable poly(D,L-lactic-co-glycolic acid) (PLGA) encapsulating chitosan/siRNA nanoparticles (NPs) were prepared by electrospinning (Figure 16.5). ... 

Electrospun nanostructured scaffolds have been intensively investigated as 3-D scaffolds for bone engineering. The principle of electrospinning is to apply high voltage on polymer solution or melt to overcome its surface tension and draw the... 

Melt spun fibers are subjected to a hot drawing process to encourage polymer chain orientation and the development of crystallinity witl the fibers. Electrospun polyester has been produced via melt spinning , but in order to render fimctionality to the resulting material, gelatin was incorporated by subsequent surface modification involving formaldehyde. This in turn improves physical fiber properties, but slows the diffusion of small molecular species within the fiber (thus, for exanqile, imdrawn polyester dyes more readily than drawn material). The shorter diffusion path out of fine fib is responsible for lower color fastness of febrics derived ifom them.
