چکیده مقاله
The aims of the current study were to Electrospinning of a double layer mat suitable for use as a wound dressing using Polyurethane and carboxymethyl chitosan sulfate Outer layer Polyurethane a polymer with high elasticity and elastic properties used to simulate the mechanical properties of suitable skin and the second layer that is in contact with the skin carboxymethyl chitosan sulfate a polymer with excellent biocompatibility and biodegradability properties that can be used as a scaffold for the growth of skin cells and accelerate wound healing Polyurethane solution in different concentrations of 6 8% was prepared in THF and DMAC solvents 60:40 v/v and electrospun on aluminum foil Scanning electron microscopy SEM was used to evaluate the electrospun nanofibers All the solutions formed beadless nanofibers with different diameters, in voltage of 10kV, 10cm tip to collector distance and the feeding rate of 1 mL h–1 Carboxymethyl chitosan sulfate CMCS was synthesized from Carboxymethyl chitosan, and then blended with poly ethylene oxide PEO and then electrospun CMCS was characterized using FTIR analysis CMCS/PEO solutions with 7%wt concentrations and the ratios of 40:60 were electrospun on the Polyurethane mat Scanning electron microscopy SEM was used to evaluate the electrospun CMCS nanofibers and formed beadless nanofibers in voltage of 20kV, 12cm tip to collector distance and the feeding rate of 0 8mL h–1
