Abstract
Gelatin and alginate are commonly used as biomaterials for making dressings because both of which have hemostasis and high tissue fluid absorption ability. In this study, gelatin and alginate are mixed at various weight ratios, the mixtures of which then undergo the freeze-drying, forming the gelatin/alginate sponges. The resulting sponges serve as the contact surface of dressings, and swelling and degradation tests evaluate the samples in terms of hydrophilicity and absorbility. The pores in the sponges are then observed by a scanning electron microscope (SEM). According to our study, with a decrease in the amount of gelatin, the determined pore size and swelling rate both increase, but the weight loss decreases.
