Abstract

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.
