Abstract
An aqueous solution of polyacrylic acid is placed in a mold, frozen, and freeze-dried to form a sponge-like polyacrylic acid structure. The sponge-like polyacrylic acid structure is compressed by the application of heat and pressure to reduce the thickness and increase the density of the sponge-like polyacrylic acid structure to form a densified polyacrylic acid structure. The densified polyacrylic acid structure is preconditioned by heating to form a wound dressing. The wound dressing can be applied to control severe, life-threatening bleeding from a wound at a wound site of a person.
