Preparation and characterization of ZnS:Cu/PVA composite nanofibers via electrospinning
ZnS:Cu/Poly(vinyl alcohol) (PVA) composite nanofibers have been successfully prepared by electrospinning technique. The formation of ZnS: Cu/PVA nanofibers were carried out by reacting H2S with Zn(AC)2:Cu/PVA nanofibers, which were electrospun from the mixture aqueous solution of Zn(Ac)2, Cu(Ac)2 and PVA. Scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray-diffr...
متن کاملPreparation and Characterization of SnO2 Nanofibers via Electrospinning
Tin oxide (SnO2) nanofibers are successfully prepared by electrospinning homogeneous viscous solutions of tin acetate in polyvinylpyrrolidone (PVP). The electrospinning is carried out by applying a DC voltage to the tip of a syringe and maintaining the tip to collector distance (TCD), i.e. at DC electric field of 1.25 kV∙cm−1. The electrospun nanofibers are calcined between 550 ̊C and 650 ̊C for ...
متن کاملPreparation and characterization of biomimetic silk fibroin/chitosan composite nanofibers by electrospinning for osteoblasts culture
In this study, we have successfully fabricated electrospun bead-free silk fibroin [SF]/chitosan [CS] composite nanofibers [NFs] covering the whole range of CS content (0%, 25%, 50%, 75%, and 100%). SF/CS spinning solutions were prepared in a mixed solvent system of trifluoroacetic acid [TFA] and dichloromethane. The morphology of the NFs was observed by scanning electron microscope, and the ave...
متن کاملPreparation and Characterization of Tetracomponent ZnO/SiO2/SnO2/TiO2 Composite Nanofibers by Electrospinning
[Zn(CH3COO)2 + PVP]/[C2H5O)4Si + PVP]/[SnCl4 + PVP]/[Ti(OC4H9)4 + CH3COOH + PVP] precursor composite fibers have been fabricated through self-made electrospinning equipment via electrospinning technique. ZnO/SiO2/ SnO2/TiO2 composite nanofibers were obtained by calcination of the relevant precursor composite fibers. The samples were characterized by thermogravimetric-differential thermal analys...
متن کاملGrowth and Characterization of Single Crystals of Potassium Sodium Niobate by Solid State Crystal Growth
Due to the toxic nature of PbO in Pb(Zr,Ti)O3 (PZT), the most common type of piezoceramic, many studies on lead-free materials are being conducted worldwide (Röedel et al., 2009). One of the most studied groups of lead-free ferroelectric materials is based on a solid solution of potassium sodium niobate, K0.5Na0.5NbO3 (KNN) (Jaffe et al., 1971; Kosec et al., 2008). However, activity in attempts...
