Polymer sponge
Polymer Sponge
Polymer sponge (pronunciation: /ˈpɒlɪmər spʌndʒ/) is a type of polymer that has been processed into a sponge-like structure.
Etymology
The term "polymer" is derived from the Greek words "poly" meaning "many" and "meros" meaning "parts". The term "sponge" comes from the Old English "spunge", which is of Latin origin from "spongia".
Definition
A polymer sponge is a porous material made from synthetic polymers or natural polymers. These sponges are characterized by their high porosity, large surface area, and the ability to absorb and hold large amounts of fluid. They are used in a variety of applications, including medical uses such as wound dressing and tissue engineering.
Related Terms
- Polymer: A large molecule composed of many repeated subunits, known as monomers.
- Synthetic Polymer: Polymers that are man-made or synthesized from petroleum oil.
- Natural Polymer: Polymers that occur naturally, such as proteins, cellulose, and rubber.
- Wound Dressing: A sterile pad or compress applied to a wound to promote healing and protect the wound from further harm.
- Tissue Engineering: A field of biomedical engineering that uses a combination of cells, engineering, and materials methods to improve or replace biological tissues.
Applications
Polymer sponges have a wide range of applications in the medical field. They are commonly used as wound dressings due to their ability to absorb exudate and promote healing. In tissue engineering, they serve as scaffolds that provide a three-dimensional structure for cell growth.
