Carbon Nanotube Enhanced Shape Memory Polymer Nanocomposites for Development of Biomedical Devices

This paper presented the synthesis and characterization of carbon nanotubes (CNTs) enhanced aliphatic urethane shape memory polymer (SMP) nanocomposites for the development of biomedical devices. Critical polymer properties, such as the glass transition temperature and shape memory function, have been tailored to desired applications, by adjusting the polymer composition. CNTs were uniformly dispersed within the polymer during nanocomposite fabrication. The synthesized SMPs nanocomposites were characterized to understand their thermal and mechanical properties. Novel biomedical devices for intracranial aneurysm treatment will be developed using these SMPs.
