hyaluronic acid ha and polyethylene oxide peo powder were dissolved in 0 1 n naoh at concentrations of 5 2 and 4 wt respectively hyaluronic acid solution was then added into the peo naoh solutions at a concentration of 1 0 w v and dissolved using a vortex mixer vortex genie2 scientific industries inc for 20 minutes until the solution became clear the maptrix u00ae ha peo blend solutions with different weight ratios from 1 1 1 to 1 1 3 were prepared for electrospinning the same electrospinning conditions were applied maptrix u00ae solution was prepared by dissolving mussel adhesive protein 10 mg in 1 ml distilled water and followed by the addition of dimethyl acetamide dmac to the maptrix u00ae solution pvdf mw 400 000 da was dissolved in dmac at 80 u00b0 c with magnetic stirring for 12 hours to form a 20 wt w v electrospinning solution the maptrix u00ae solution 1 ml was added to the pvdf solution 4 ml to get 5 ml of electroprocessable functional composition the electroprocessable composition was transferred to a spin pack using a metering pump and then electrospun by applying high voltage to the spin pack using a high voltage controller the voltage used here was adjustable within the range of 19 to 20 kv and as a collector plate an electrically conductive metal was used fig3 shows scanning electron microscope sem images of representative pvdf fibers of the invention electrospun from pvdf maptrix u00ae and pvdf polydopamine solution 21 mg of dopamine was dissolved in distilled water 1 ml and very slow oxidation reaction was allowed for 3 to 6 hours to form a precursor.
