Abstract
A low-energy Ar+ ion beam was used to modify the surface of a poly(ether imide) (PEI) powder. The modification was promoted by the oxygen gas injected during the irradiation. The surface functional groups of the modified PEI were identified with X-ray photoelectron spectroscopy (XPS). The XPS results show that the bonds originally contained in the imide ring structure are destroyed as a result of random collisions with incident ions and energy transfer to the PEI atoms. Ion-beam irradiated PEI (IBPEI) blends with a thermotropic liquid crystalline polymer (TLCP) show more homogeneous rheological behavior than pristine PEI blends, which is attributed to an interaction between the IBPEI and the TLCP phase. Ion-beam irradiation has a strong effect on the blend morphology, the size of the dispersed phase being remarkably reduced (from 5.3 to 3 μm) and the TLCP phase being finely dispersed. Also, the adhesion between the TLCP phase and the IBPEI is definitely improved. The theoretically calculated interfacial t...
