Query: Smart viscoelastic and self-healing characteristics of graphene
  nano-gels   Readily synthesizable nano-graphene and poly ethylene glycol based stable
gels have been synthesized employing an easy refluxing method and exhaustive
rheological and viscoelastic characterizations have been performed to
understand the nature of such complex gel systems. The gels exhibit shear
thinning response with pronounced yield stress values which is indicative of a
microstructure where the graphene nanoflakes intercalate with the polymer
chains and form a pseudo spring damper network. Experimentations on the
thixotropic behavior of the gels indicate that the presence of the G nanoflakes
leads to immensely augmented structural stability capable of withstanding
severe impact shears. Further information about the localized interactions of
the G nanoflakes with the polymer chains is revealed from the amplitude and
frequency sweep analyses in both linear and nonlinear viscoelastic regimes.
Massively enhanced cross over amplitude values are recorded and several smart
effects such as enhanced elastic behavior at increasing forcing frequencies are
registered. Structural resonance induced disruption of the elastic behavior is
observed for the gels for a given range of frequency and the proposition of
resonance has been justified mathematically. It is observed that post this
resonance bandwidth, the gels are able to self-heal and regain their original
elastic behavior back without any external intervention. More detailed
information on the viscoelastic nature of the gels has been obtained from creep
and recovery compliance tests and justifications for the spring damper
microstructure has been obtained. Smart features such as enhanced stress
relaxation behavior with increasing strain have been observed and the same
explained based on the proposed microstructure.
