“…Many functional nanoparticles, such as SiO2 [3,4], Al2O3 [5], Fe3O4 [6,7], and TiO2 [8,9], have been recently employed as sorbents to remove Pb 2+ from water. These sorbents have high adsorption capacity and rapid sorption rate for Pb 2+ because of the larger surface area of nanoparticles.…”

“…Figure.3.d,e,f show that spots on the nanofiber are decreased by adding TiO2 nanoparticles into the PVA/Chitosan. It is supposed that by adding TiO2 nanoparticles into the PVA/chitosan, the conductivity of electrospun was an increase [10]. Table.2.…”

Abstract. Nanofiber PVA/Chitosan/TiO2 have been prepared by electrospinning method. Electrospinning was performed at a voltage 15 kV, with a tip-collector distance of 14 cm. A novel nanofibers mat was fabricated in various contents of PVA, Chitosan, and TiO2. The structure of PVA/Chitosan/TiO2 was examined by FTIR, XRD, and SEM-EDAX. The results showed that PVA/Chitosan/TiO2 nanofiber was successfully formed. SEM observation showed that the fiber had several hundred nanometers with a smooth surface and distributed randomly. It was also observed that nanofibers containing chitosan show smaller diameter than that of without chitosan. The beads on the nanofibers are decreased by adding TiO2 nanoparticles into the electrospun solution.

“…However, this process can often be multi-stage and time consuming requiring particles to be pre-synthesised and subsequently functionalised to reduce the effects of particle agglomeration and allow homogenous distribution throughout the nanofibers. A number of different nanoparticles have been incorporated into nanofibers using this technique including silica [95], titanium oxide (TiO 2 ) [96], Al 2 O 3 ,F e 2 O 3 , SiO 2 and ZnO [97]. Although this technique can be limiting it can also be seen as advantageous for some applications with pre-synthesis of nanoparticles is generally the only suitable method for preparing functionalised nanoparticlenanofiber composites.…”

“…This can also be achieved by immersing nanofibers in a nanoparticle solution, as presented by Razzaz et al with TiO 2 nanoparticles [96], but this requires pre-synthesis of nanoparticles. Other researchers have included a precursor in the electrospun material and synthesised the particles within the fibres.…”

Nanofibers are an important material for regenerative medicine as they have a commensurate morphology to that of the macromolecular matrix that supports and houses the growth of cells and tissues within the body. Electrospinning is widely used to fabricate non-woven structures on the nanoscale and the versatility of the technique has widened the application of nanofibers. This is due to ease of extending nanofiber functionality through the incorporation of active materials both during and after electrospinning. Recent developments in electrospinning devices, such as needle-free systems, have reinvigorated research as these advances now allow fabrication of nanofibers at commercial scales. The process of electrospinning has a number of operating parameters that are adjusted in optimisation to achieve ideal fibres and a multitude of instrument configurations can be adopted to achieve the required manufacture. The innate properties of nanofibers, such as high surface area to volume ratio, have many proven benefits for regenerative medicine and the chapter examines these before discussing how functionality can be further improved. Numerous materials can be incorporated in the manufacture of electrospun mats, however when choosing materials for regenerative medicine, biocompatibility and biodegradability are the dominant functionalities that are required.
