In this study, soft hydrogel layers reinforced with
cotton nonwoven were produced to use as a surgical dressing. Solution
consisting of two polymers (O-carboxymethyl chitosan and polyethylene glycol)
were chemically cross-linked using polyethylene glycol diglycidyl ether.
Optimum hydrogel formulation was determined considering mechanical parameters. After
casting of the selected formulation onto nonwovens, samples were freeze-dried. To
increase the swelling capacity of the hydrogels, nano/micro-sized cellulose was
added. Physical features, dynamic fluid handling capacity, water vapor
permeability, morphology (SEM), and chemical structure (FT-IR) were examined. Antibacterial
and in vitro cytotoxicity assays were
applied to the formulation showing the best characteristics.
