Effect of Plasma Treatment on the Physical Properties of PMMA/HA Composite

Abstract

Studies of plasma produced at atmospheric pressure in recent years have gained increasing importance and the focus of researchers has increased to use it in most practical applications, especially in industrial and medical applications. DBD plasma has been used in this research to study the mechanical properties of compound materials (PMM/ HA) that have been prepared in the laboratory. PMMA polymer was used as the base material and reinforced with a nanomaterial consisting of hydroxyapatite (HA) to form a bioceramics compound. The effects of DBD plasma on the mechanical properties of the prepared nanocomposite materials such as hardness, bending, and tensile tests were studied. And through the tests, it was found that there is a significant improvement in the properties of the nanocomposite materials (PMMA/ HA) after treatment by plasma at three different times (30, 60, 90) seconds, it was found that the increase stress, Young modulus and hardness increases with increasing in the duration of the effect of the plasma on the samples.
