文摘
- •
Ultrananocrystalline diamond (UNCD) integration with PyC components of mechanical heart valves has been reported.
- •
Carbide bonding, graphite and film stress minimization, and CTE compensation between PyC and UNCD have been developed.
- •
UNCD on PyC passed aggressive scratch test with a load up to 100 N and exhibited robust protection on the PyC substrate.
- •
Thrombin generation experiment suggests that UNCD surface seems to be “invisible” to the interacted fresh human platelets.
