Fabrication and Evaluation of Ceramic Microtubes by Extrusion of Preceramic Polymers

Abstract

This report results from a contract tasking University of Bologna as follows: This work will explore the fabrication of microtubes using commercially available, specialized equipment developed for micro-extrusion of conventional polymers. In this project, preceramic polymers, yielding Si-(O)-(N)-C upon pyrolysis at high temperature, will be used instead of conventional thermoplastic polymers. Microtubes of various diameters will be manufactured using both a single extrusion and a co-extrusion approach. In the latter method, a sacrificial material will be co-extruded with the preceramic polymer, and later eliminated to reveal the desired porosity. Multilumen microtubes will also be produced. The fabricated microtubes will be characterized in terms of mechanical properties and morphology, using several available analytical techniques.
