Poly(hydroxy‐oxazolidone) Thermoplastic Elastomers for Safer, Greener and Customizable Blood‐Contacting Medical Devices

Advanced Healthcare Materials, EarlyView.
A poly(hydroxy‐oxazolidone) (PHOx) is synthesized from CO2‐based precursors, enabling the up‐cycling of this waste material. After synthesis, PHOx shows thermoplastic properties, and can therefore be processed by many temperature‐dependent techniques. PHOx is hemocompatible, anti‐adhesive, and biocompatible, which is demonstrated in vitro and in vivo ...
