Development of a Novel Biomaterial for Spinal Implant Purpose

Abstract

In this study, we have successfully fabricated a novel biomaterial polymer, possessing a 3D microarchitecture, with a simple and inexpensive manufacturing process. This biomaterial is a polydimethylsiloxane (PDMS) and poly(ether) ether ketone (PEEK) composites, which possesses highly porous structure, mimicking the mechanical and heterogeneous properties of the human body. For biocompatible approaches, a thin film of TiO2 was deposited on the surface of the polymer using atomic layer deposition (ALD). Based on scanning electron microscopy analysis, universal tensile testing and x-ray photoelectron spectroscopy analysis, it was confirmed that this novel biomaterial has a high potential of becoming a spinal implant material in the future.
