Polyurethane (PU)

an organic polymer composite material with the superior properties

is currently one of the most widely used polymers with viscoelasticity and biodegradability. PUs have been a hot topic surface materials

coatings

packaging materials

indoor floors of buildings

artificial leather and biomedicine

due to its excellent mechanical properties

abrasion resistance

workability and flexibility. Among them

the most forward-looking is that the application as a functional material in the biomedical field

such as artificial organs

tissue engineering scaffolds

wound dressings

medical membranes

and three-dimensional cell culture substrates. Based on this

this paper reviews its research progress and advanced applications in the biomedical field at home and abroad

and looks forward to its future development direction.
