“Nanofoamed Polyetherimide Nanocomposites and Their Potential Applications

(VIDEO CONFERENCED FROM AUSTIN, TX)
Nanofoamed polyehterimide (PEI) nanocomposites are a class of novel material with pore
size on the level of 100 nm. Due to the small pore size and the added nanofillers,
nanofoamed PEI nancomposites exhibit multifunctional properties that are highly
desirable for many emerging industrial applications. The current trend in industry
is to consolidate material such that multiple functions that used to be performed
by different components can now be performed by a single one made of a multifunctional
material. Nanofoamed PEI nanocomposites are light yet strong given their reduced
density. It has improved electrical conductivity, which is beneficial to the overall
structural performance for applications such as new generation airplanes and large
wind turbine blades. The unique open-celled nanoporous structure also provides an
opportunity to incorporate bactericidal nano-additives for water purification. This
presentation focuses on the fabrication and property characterization of the nanofoamed
PEI nanocomposites. The nano additives studied include carbon nanofiber, carbon nanotubes,
and silver nanoparticles. The nanoporous structure is created using a supercritical
solid-state foaming process. Mechanical and electrical properties, pore size, and
relative density are characterized.
