文摘

Thin film networks of multiwalled carbon nanotubes (MWCNTs) were prepared by exerting chemically induced capillary forces upon the nanotubes.During this process MWCNTs undergo a transformation from being a vertically aligned structure to an interlocking resistive network ofinterconnected nanotubes, whose main feature is a regular three-dimensional (3D) sieve architecture. Due to their structural characteristics atthe nanoscale level, 3D-MWCNT-based networks are in principle ideal candidates for scaffolds/matrices in tissue engineering. Their potentialapplication in this field was confirmed by extensive growth, spreading, and adhesion of the common mouse fibroblast cell line L929.
