Super absorbent gauze could save troops' lives

The video discusses a new absorbent wound dressing made from polystyrene and rubber, capable of absorbing up to 800% of its weight in liquid. Its plasticity enhances strength and flexibility, while acrylic acid provides super absorbent properties, aiding in faster blood clotting. As the material swells, it forms a tough hydrogel shell, three times stronger than gauze, offering improved protection for wounds.
