To systematically alter the level of adhesion between the embedded nanoparticles and the host epoxy matrix, Mg/Al and Zn/Al LDHs have been intercalated with 2-naphthoate, 6-amino-2-naphthoate (6A2N) and mixtures of the two into an epoxy matrix consisting of a blend of diglycidyl ethers (diglycidyl ether of bisphenol A, DGEBA, and digylcidyl ether of 1,4-butanediol, DGEBD).† By varying the amount of the amine functional group, the ability of the host matrix to bond to the nanoparticles will be controlled.† The characterization and performance of the LDH-epoxy nanocomposites as these nanomaterial properties are varied will be discussed.
