Description

technical field

[0001] The invention belongs to the technical field of polymer materials, and in particular relates to the preparation of a novel adhesive, antibacterial and temperature-resistant functional hydrogel and its application in diabetic foot wound dressing. Background technique

[0002] Diabetic foot is one of the most common complications in diabetic patients, which increases patients' risk of morbidity, infection, non-traumatic amputation, and even early death. Due to the high-sugar wound environment, diabetic foot has become a chronic wound disease easily infected by bacteria, which seriously affects the physical and mental health of patients and also brings a heavy social and economic burden. In clinical treatment, wound dressing has gradually become the main strategy to promote diabetic foot wound repair. Traditional diabetic foot wound dressings are mainly dry dressings such as electrospun fibers, absorbent cotton, natural or synthetic gauze (bandages), whi...
