Dendrimers have superior performances as a new class of toughener.

Dendrimers have superior performances as a new class of toughener.
Using a certain dosage of dendrimers(CYD-CD215/CYD-CR111/CYD-CV111) to modify epoxy resin, while improving the toughness, the strength remained unchanged.When dendrimer dosage is 16%, bending performance reaches maximum, bending strength improved from 55. 37 MPa to 60. 32MPa, bending modulus improved from 3544. 89 MPa to 3758. 32MPa, meanwhile impac
