Linan An’s recent research focuses on polymer-derived ceramics synthesized by thermal decomposition of polymer precursors at 400-1000 oC. This new class of materials, based on amorphous alloys of silicon, carbon, boron, and nitrogen, exhibits excellent mechanical and thermal properties up to 1800 oC, promising for ultrahigh temperature applications. The nanostructures and composites, thereby the properties, of PDCs can be tailored by modifying the chemistry of the precursors. This offers a unique opportunity to manipulate materials at the atomic level to achieve improved properties and multifunctional behavior. The chemical route is also leading to cost-efficient and flexible manufacturing techniques for the fabrication of ceramic components with these interesting materials.

An’s research group focuses on understanding nanostructure-properties relationships, designing novel multifunctional materials and synthesizing ceramic composites such as carbon nanotube reinforced PDC.
