Quantitative analysis of the polyurethane composites with non-organic nanofiller for use in implants of intervertebral disc

Abstract

The aim of this research was to develop a composite material to be used as an elastomeric core of the artificial intervertebral disc. Two types of polyurethane composites with non-modified SiO 2 and SiO 2 modified NH 2 group were obtained. The composites made of these materials have different filler content. The effect of modifying fillers for the structure and properties of these materials were investigated.
