Surface Endothelialization of Polyurethanes

open access: yesProcedia Engineering, 2013
AbstractOne of the contemporary challenges for cardiovascular tissue engineers is to design hemocompatible biomaterials that promote neo-tissue formation. Despite many years of intensive research materials used to fabricate synthetic implants still cause clot formation in the bloodstream, which can have fatal consequences for the patient.

Covalent Adaptable Networks with Associative Siloxane Exchange Enabled by Amide‐Based Internal Catalysis: Designing for Reprocessability and Extrudability by Increasing the Cross‐Link Density

open access: yesAdvanced Functional Materials, EarlyView.
Internally catalyzed siloxane dynamic chemistry is demonstrated resulting from amides covalently linked through alkyl chains to siloxanes. The alkyl length in the siloxane‐containing monomer tunes the network cross‐link density. Siloxane exchange dynamics are faster with increasing cross‐link density, because associative exchange is second order in ...
