A Chemometric Study Of Alumina/PEEK and Hydroxyapatite/PEEK Suspensions Prepared For Electrophoretic Deposition Of Multifunctional Coatings

摘要

Poly(etherether-ketone) (PEEK) suspensions in ethanol and isopropanol containing also a-alumina and hydroxyapatite powders were studied. An innovative method was used in the study of the quality of suspensions. We studied suspensions by means of zeta potential and grain-size measurements. The comparison amongst the different suspensions was carried out by using statistical and chemometric tools, especially by the use of an explorative test based on the Principal Component Analysis (PCA). The chemometric analysis was performed by involving different combinations of each type of powder and each type of solvent.
