This study presents a bilayer structure as a skin scaffold comprised of an electrospun sheet
layer made of polycaprolactone and polyvinil alcohol and a porous hydrogel layer made of
chitosan and gelatin. The hydrogel layer was fabricated by employing the freeze-gelation
technique. The bilayer structure was achieved by pouring the hydrogel solution on the
electrospun sheet at the bottom of a mold followed by the freeze-gelation technique to obtain
a porous structure in the hydrogel. The hydrogel and hydrogel-electrospun samples were …
