Abstract
A process for purifying raw carbon nanotubes to obtain a content in metallic impurities of between 5 ppm and 200 ppm. The process includes an increase in the bulk density of the raw carbon nanotubes via compacting to produce compacted carbon nanotubes. The process further includes sintering the compacted carbon nanotubes by undergoing thermal treatment under gaseous atmosphere in order to remove at least a portion of the metallic impurities contained in the raw carbon nanotubes, and consequently producing purified carbon nanotubes. These purified carbon nanotubes are directly usable as electronic conductors serving as basis additive to an electrode material without requiring any subsequent purification step. The electrode material can then be used to manufacture an electrode destined to a lithium-ion battery.

Abstract
Foamed acrylic materials using both traditional chemical blowing agents as well as foamable microspheres. The acrylic foams have improved density reduction, optical properties, and insulation properties. The acrylic foams can be formed by traditional melt processing methods (extrusion, blow molding, etc.) as well as innovative foaming methods, such as foaming during or after polymerization. One method involves the use of expandable microspheres blended with monomers, the monomers then polymerized through bulk polymerization in cell cast, infusion, or compression molding processes. This method can be effectively used to produce composite foam structures.
