Carbon nanotubes based functional materials for MSL and biosensor applications.

摘要

In this thesis, several carbon nanotubes (CNTs) based functional materials have been successfully synthesized and systematically characterized. Their applications for MicroStereoLithography (MSL) and biosensor were further explored.; A new mild oxidization method for oxidizing multi-walled CNTs was developed using potassium permanganate as the oxidant and assisted with phase transfer catalyst. The novel oxidization procedure gives significantly higher yield and high functional group density. Facilitated with the above functional groups, a variety of homogeneous polymer/CNTs nanocomposites were prepared through either chemical or physical interactions and they were systematically characterized. UV curable oligomers have been attached to the wall of the oxidized carbon nanotubes, and they were cured by MicroStereoLithography (MSL) UV light laser with both free radical and cationic polymerization mechanisms. Furthermore, graphite and several CNTs-based glucose thick film biosensors are fabricated and evaluated.
