Abstract
Precise organization of nanomaterials with functional
biomolecules play a key role in many natural materials.
In this work, single-walled carbon nanotubes were
functionalized by a self-assembling amphiphilic protein
that enabled their dispersion into nanofibrillated
cellulose matrix. The protein contained a hydrophobic
patch and a glycosylated domain and due to its dual
functionality, it was able to assemble at the interface
of the carbon nanotubes and the nanofibrillated cellulose
and thus enhance the interactions between them. The
electrical conductivity of the nanocellulose/carbon
nanotube composites was improved by approximately 5-fold
when the protein modified nanotubes where applied. Also
improvement of the mechanical properties due to the
proteins was observed.
