Bio-inspired synthesis and self-assembly of
few layer graphene

The future development of advanced materials depends
on several aspects, which are first of all linked to
synthesis and then exploitation of the materials in an
efficient way. This concerns also the graphene based
materials and despite the huge number of efforts devoted
to the synthesis of graphene and few layer graphene
(FLG) there is still luck of the methods allowing their high
scale production together with environment respect. Their
efficient use in composites, polymers and films in order
to provide or enhance graphene-related properties such
as high conductivity, transparency, flexibility, mechanical
resistance will depend on the way these “nano” materials
are arranged in the macroscopic media. Herein, the bio-
compatible, high yield production of solution processable
FLG is presented (patent)1 together with a new approach
of bio-inspired FLG self-assemblies into fractal like
patterns (presently under patent application). Such FLG
self-assemblies reduce the percolation threshold between
FLG flakes allowing the percolation at lower amount
of FLG for a given surface if compared to the random
arrangement (fig. below).2 This can find the application
in transparent conductive films (TCF), where the FLG
self-assemblies patterns can be optimized in order to
achieve variable transparency-conductivity properties
according to the TCF final use. This interesting finding
recalls the natural tendency of Matter to self-organize into
functional systems. The fractal like, branched structures
are commonly observed in numerous natural systems
being in charge of transport function, such as river beds,
trees or neural system.
