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 impact strength reaches maximum, from 3. 10 kJ /m2 to 4. 64 kJ /m2, improved almost 50%.
