The purpose of this research was to extend to usage of hydrogel wound dressings in order to use over a larger range of wound types. Wounds that produce medium to high exudate levels usually use foam dressings made from polyurethanes. Therefore, moderate and heavy exudating wounds are an area where hydrogel dressings are currently not used, because their current properties do not allow hydrogel dressings to absorb the exudate fast enough. To achieve this goal the fabrication of hydrogels, which possess a foamed structure, but still maintain all the good properties of conventional hydrogel wound dressings was the goal. The main methods used to evaluate the porous hydrogels were swelling ratio and rheology. The gels were also assessed by examining visual appearance and handling properties. The swelling was measured by cutting a 1cm2 piece of gel ad then immersing in water. The gel was measured and weighed every 5 mins for 30 mins, at 1 hour and after being left overnight. The rheology testing was preformed on a Bohlin Gemini HR nano rotational rheometer using a frequency and strain sweep of 0.1 - 25 Hz and 0.1 - 150% deformation respectively. All of our hydrogels are made by redox free radical
