- We studied enhanced interfacial adhesion between a flexible amorphous polymer (polystyrene, PS) and a
semi-crystalline polymer (a polyamide, Ny6). The surface modification of PS to provide functional groups reacting with
the functional groups of Ny6 was carried out with ion-beam and/or plasma treatment. These surface modifications were
found to significantly alter the interfacial adhesion strength between PS and Ny6. Though the fracture toughness was
varied depending on the process, its overall behavior was quite similar with one another; the fracture toughness
increased with increasing bonding temperature and bonding time, passed through a peak, and then decreased with
further increase of the bonding time or temperature.
