TL;DR
This study explores hydrogel wound dressings made with sodium alginate, PEGDA, and ginger extract, finding that a specific combination offers good water absorption and acidity for wound healing.
Contribution
The novel contribution is the evaluation of ginger extract as a modifier in hydrogels for wound dressings, influencing hydrophilicity and acidity.
Findings
The 4%Alg/12%PEGDA hydrogel showed the best water absorption and slowest weight loss.
The 4%Alg/12%PEGDA/12%EEI hydrogel had the highest hydrophilic properties and ionic conductivity.
Adding ginger extract increased acidity, which may benefit wound healing.
Abstract
Natural compounds incorporated into hydrogel materials have been widely used to support wound healing due to their numerous properties. The aim of this research was to produce hydrogel biomaterials with the addition of adjuvants, such as sodium alginate and polyethylene glycol diacrylate (PEGDA) with the addition of ethylene ginger extract (EEI). A thermogravimetric (TG) study, differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), water absorption testing and microscopic analysis were carried out to determine the properties of the developed dressing. The conducted research showed that the 4%Alg/12%PEGDA hydrogel was characterized by the best water absorption values and the slowest weight loss as a function of temperature. Additionally, the 4%Alg/12%PEGDA hydrogel had the best ability to dissipate stress in its structure. It was found that the addition of the ginger…
