Melt electrospinning

In melt electrospinning, silver nanoparticles are doped in molten polymer to prepare a silver/polymer composite. It is extremely difficult to disperse silver nanoparticles uniformly into the polymer matrix. This problem arises mainly due to the ease with which nanoparticles agglomerate and also, the high viscosity of the molten polymer. In the past few years, compounding of PP with nanosilver using a compounding extruder has gained popularity. [Pg.64]

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... [Pg.835]

Glass fibers are industrially produced from melt, above 700°C, that is why it is not used for melt-electrospinning. Bioactive glass fibers have already been produced via electrospinning from sol-gel [152] but they are not strongly related to PPCs. [Pg.334]

Another modification involves removing the potentially cytotoxic solvent from the electrospinning equation in a process called melt electrospinning [159]. This process involves tight control of temperature, and for the case of a PU based on BDl, PCL, 1,4-butanediamine (BDA), and BDO involved temperatures of 220-240 °C [160]. [Pg.91]
