Article
Nanocomposites attract the attention of researchers due to the increasing demand on materials having unique properties. Incorporation of nanoparticles into polymers considerably improves some materials properties such as thermal stability. In current study, PMMA/SiO2 hybrid nanocomposites including ungrafted and grafted silica nanoparticles have be...
Article
In current study, various types of electrospun scaffolds have been prepared including poly(L-lactide-co-ε-caprolactone), collagen type I, hydroxyapatite nanoparticles (HAp) and silver doped hydroxyapatite particles (Ag-HAp). 13C-NMR, 1H-NMR, FT-IR, XRD, TEM and EDS analyses were performed to characterize the synthesized copolymer and nanoparticles....

Surfaces of previously synthesized Hydroxyapatite particles (HAP) have been modified with polyethylene glycol functional silane (PEG-400Si). For the surface modification of HAP, firstly, synthesis of PEG-400Si was performed by urethane reaction of hydroxyl and isocyanate groups. Then, HAP was synthesized by sol-gel method. Afterwards, surface modif...

The antibacterial effect of silver on knitted and nonwoven structures has been investigated. Three types of interlocked knitted fabrics (100% polyester, 100% viscose and 50%/50% polyester/viscose) were scoured and treated with silver ions by pad-dry-cure method. A nonwoven fabric (100% bleached cotton) was also treated with silver ions by using a s...
Article
PA6 nanofibers were electrospun successfully and sputter coated with gold and palladium to create functional nanofibrous membranes that possess electromagnetic shielding ability. Properties of the electrospinning solutions were analyzed in terms of viscosity, conductivity and pH values. Coating thicknesses of the nanofibrous membranes were determin...
