Modifications induced in photocuring of Bis- GMA/TEGDMA by the addition of graphene nanoplatelets for 3D printable electrically conductive nanocomposites

The incorporation of nanoreinforcement in photocurable polymeric matrices can strongly affect the degree of curing and properties of the final nanocomposites as well as the process parameters for 3D printing. Particularly, the addition of GNPs in contents from 1 up to 10 wt% limits the degree of cur...

Particularly, the addition of GNPs in contents from 1 up to 10 wt% limits the degree of curing to 60% in Bis-GMA/TEGDMA. The increase up to 10 wt% causes a diminution of ~20% in the mentioned property.
