The structural and mechanical properties of tissue engineered environments are crucial for successful cellular growth and tissue repair. Electrospinning is gaining wide attention for the fabrication of tissue engineered scaffolds, but the small pore sizes of these scaffolds limit cell infiltration and construct vascularization. To address this problem, we have combined electrospinning with phot...

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, the possibility of large scale productions combined with the simplicity of the process makes this technique very attractive for many different applications. Biomedical field is one of the important app...

Electrospinning is an efficient method by which to produce scaffolds composed of nanoscale to microscale fibers, which are comparable to the fiber diameters of native components of the extracellular matrix. In electrospinning, a polymer solution is pumped through a syringe that is connected to a high voltage source. As a droplet forms at the tip of the needle, electrostatic repulsions form long...

An electrospinning process is a multi-phase and multi-physicical process with flow, electric and magnetic fields coupled together. This paper deals with establishing a multi-phase model for numerical study and explains how to prepare for nanofibers and nanoporous materials. The model provides with a powerful tool to controlling over electrospinning parameters such as voltage, flow rate, and oth...

A novel, simple geometry for high throughput electrospinning from a bowl edge is presented that utilizes a vessel filled with a polymer solution and a concentric cylindrical collector. Successful fiber formation is presented for two different polymer systems with differing solution viscosity and solvent volatility. The process of jet initiation, resultant fiber morphology and fiber production r...

Biodegradable poly(L-lactic acid) (PLA) fibrous scaffolds were prepared by electrospinning from a PLA melt containing poly(ethylene glycol) (PEG) as a plasticizer to obtain thinner fibers. The effects of PEG on the melt electrospinning of PLA were examined in terms of the melt viscosity and fiber diameter. Among the parameters, the content of PEG had a more significant effect on the average fib...

Rubber composite fibers containing silver nanoparticles with high morphological stability were prepared through combination of electrospinning and in-situ chemical crosslinking. The composite fibers included those of Ag/polybutadiene rubber (BR), Ag/polyisobutylene-isoprene rubber (IIR), and Ag/silicon rubber (SiR). During the study, Ag nanoparticles (Ag NPs) were first generated through reduci...
