Fabrication of polymeric composite nanostructures containing ferritin nanoparticles and carbon nanotubes

초록

Composite nanofibers including ferritin nanoparticles or multiwalled carbon nanotubes (MWCNTs) were fabricated because of their potential advantages for the enhancement of physical properties such as elastic modulus and electric conductivity. Ferritin was homogeneously incorporated in polymeric nanofibers. However, excessive addition of CNTs to a polymer solution resulted in the fabrication of composite nanofibers with rough surfaces. Finally, PVA/ferritin/CNT composite nanofibers were fabricated, and they had smooth surfaces, and maintained well dispersion of ferritin and CNTs. The composite nanofibers would be applicable to artificial muscles requiring the enhanced physical properties.
