Producing nanofibers with controlled size

(Nanowerk News) Researchers studied the effective parameters on the production of polymeric nanofibers through electrospinning method ("Effect of electrospinning process parameters of polycaprolactone and nanohydroxyapatite nanocomposite nanofibers").
Nanofibers with desirable diameter and size can be produced using the results of this research by optimizing the process conditions.
In this research, composite nanofibers of polycaprolactone/hydroxyapatite nanoparticles were produced through electrospinning method, and the effects of various process conditions were studied on the average diameter of the produced nanofibers.
Results of this research can detect a range of variables that lead to the production of nanofibers at desirable size. Therefore, production costs reduce while the desirable nanofibers are produced faster. Effective parameters that affect the average diameter of the final nanofibers are polymer concentration, voltage and current of solution.
The produced nanofibers can be used as three dimensional scaffolds in tissue engineering to cure and substitute damaged tissues, including bones. Tissues in human body are made of nanometric fibers. Therefore, scaffolds containing nanofibers produced through electrospinning method can be considered as appropriate environment for the growth of the cells.
More textiles with waterproof and antibacterial properties can be produced by using these nanofibers in case other polymers are added to them. In addition, polymeric nanofibers can be used as filters and membranes in separation and purification industries.
