Estudo investigativo das características morfológicas e mecânicas do polímero Poli(éter-éter-cetona)(peek), com a proposição de aplicação na substituição total de corpos vertebrais da coluna.

Abstract

The growing demand for biomaterials more efficient for composite implants or prostheses led to an increase in research concerning the development of these with a lifetime longer, however, without their main requirements are lost that are biofunctionality and biocompatibility. Thus, the poly (ether - ether - ketone) (PEEK) emerges as a candidate leader in biomaterials for implants composition to present an excellent combination of characteristics such as strength, durability, rigidity and chemical resistance. Furthermore, it can be used in combination with other components, thus forming a composite material themselves, which are the most promising types of materials currently applicability to biomaterials. In this regard, the main objective of this study is to evaluate the influence of the variation of processing parameters, the properties of the composite material PEEK and Sodium chloride (NaCl) and through characterizations, determine its application viability as a biomaterial. for this research samples were processed through an experimental design 23 where the samples referred to in the text as the samples for subsequent characterizations, passed by varying parameters such as, Load (Ton.) of compaction, temperature (° C) melting the material and the time (min) processing. the results of the characterization of the test material as the morphological and mechanical properties showed that the material had excellent physico-chemical qualities by analysis FTIR, OM and SEM and also a great resistance to mechanical compression tests to which it was submitted. so that the material showed promise for the suggested application of the vertebrae replacement when compared to mechanical tests in vitro samples collected from cadaveric individuals. Therefore, it is concluded that the material has excellent properties of mechanical and morphological resistance enabling it possibly to the desired application, however, it must be subjected to further analysis to be actually framed as a biomaterial for implants composition for replacing vertebrae of the human spine.
