Nanoporous silica membranes fabricated using multiwalled carbon nanotubes.

Nanoporous silica membranes were fabricated using 3-aminopropyltriethoxysilane (APS) and acyl chloride-functionalized multiwalled carbon nanotubes (MWCNTs). The amine groups of silane reacted with the functional groups (e.g.

Electrical and mechanical properties of poly(L-lactide)/carbon nanotubes/clay nanocomposites.

An organoclay containing epoxy groups, twice-functionalized organoclay (TFC), was synthesized by reacting (glycidoxypropyl)trimethoxy silane with Cloisite25A (C25A), which had already been modified with an amine compound. The introduction of epoxy groups to the clay surface and carboxylic group-functionalized multiwalled carbon nanotubes (MWCNTs) improved the interfacial adhesion between the poly(L-lactide) (PLLA) and nano-sized fillers when melt-compounded. The PLLA/MWCNTs/TFC nanocomposites showed superior tensile properties to those of PLLA and PLLA/CNTs.
