Abstract
To understand the interface phenomena between metals and 4-META/MMA-TBBO resin, the relationship between the amount of hydroxyl groups on the surface of the metal and that of the resin adsorbed by the metal, the relative orientation of functional groups in the resin to the surface of the metal and the bonding states between the metal and the resin were examined using Fourier transform infrared reflection absorption spectroscopy(FT-IR-RAS)and X-ray photoelectron spectroscopy(XPS).The amount of the resin absorbed by the metal increased with the increase of hydroxyl groups.In addition, in the case of non-precious metals, C=O and C-O axes in polar groups in the resin relatively oriented normal to the surface of the metals and the metal-complexes were formed at the interfaces.On the other hand, in the case of the precious metals, such phenomena did not occur.That is, 4-META/MMA-TBBO resin adheres to the non-precious metals more strongly than the precious metals.
