Protonated 2,4,6-tris-( dimethylaminomethyl) phenol( DMP-30) was employed as surfactant for modification of pristine Na+-clay. By the new acetone-clay slurry compounding approach,highly exfoliated epoxy / clay nanocomposites were fabricated. Transmission electron microscopy( TEM) observation displays the organoclay platelets uniformly dispersed and highly exfoliated in the entire epoxy matrix. Differential scanning calorimeter( DSC) test indicated that Tgof the resultant nanocomposites is enhanced by 10 ℃ a...
