Abstract
Novel hydroxyapatite-based hybrid materials with controlled porosity and good adhesion to silicon surfaces were designed as bio-package for MEMS with potential application for implants in the human body. These materials were prepared using synthetic Hydroxyapatite (HAp) powder with three different polymeric agglutinants. These porous materials have high ceramic content (up to 60 wt.% respect to resin) with a pore size between 100 and 350 microns and a pore volume fraction in the 25–60% range. These hybrid materials have high wearing resistance and hydrolytic stability. The samples were characterized mechanical and morphologically using XRD, SEM, densitometry, abrasion and mechanical tests.
