Metal-matrix interface in reinforced glass ionomers

摘要

Objective: In reinforced materials, interfacial bonding is critical for efficient transfer of stress from the matrix to the reinforcement. The goal of this study was to characterize the physical and chemicalnature of this interface in three metal-reinforced glass ionomers. Two of them were commercial, ESPE-Ketac Silver (KS) and GC-Miracle Mix (MM), and the third, EX, was experimental. Methods: The techniques of scanning electron microscopy (SEM) and infrared spectroscopy (IR) were used to accomplish the stated goal.
