TLDR
It can be confirmed by looking at the statistical results of the filler-to-filler distance obtained from the digital processing of the fracture surface images that the various oxygenated functional groups of graphene oxide can help improve the dispersion of the filling and that the introduction of large phenyl groups to the graphene basal plane has a positive effect on the disp immersion.Abstract:

Microstructure, residual stress, and intermolecular force distribution maps of graphene/polymer hybrid composites: Nanoscale morphology-promoted synergistic effects
TL;DR: In this paper, the authors investigated surface topography, chain ordering, residual stress distribution, force curves and force volume imaging using micro-Raman spectroscopy, Raman mapping, atomic force microscopy and force spectrum imaging.

Hierarchical mode I and mode II interlaminar toughening of Z-pinned composites using 1D and 2D carbon nanofillers
TL;DR: In this paper, a hierarchical approach of incoporating carbon nanofillers and z-pins to further improve delamination toughness was proposed. But the results of the interlaminar fracture toughness reveal that the 1D nanophillers induce synergistic (i.e. greater-than-additive) improvements to both modes I and II delamination resistance of z-pinned laminates, whereas the 2D nanofiller show virtually no effect.

Thermally conductive composite film filled with highly dispersed graphene nanoplatelets via solvent-free one-step fabrication
TL;DR: In this paper, a solvent-free melting process was proposed for fabricating high-conductivity polymer composite films filled with highly dispersed GNP fillers using X-ray micro-computed tomography (micro-CT), a non-destructive three-dimensional (3D) analysis technique that helps to analyze the internal structures of composite films with precision.

Influence of hybrid graphene oxide-carbon nanotube as a nano-filler on the interfacial interaction in nylon composites prepared by in situ interfacial polymerization
TL;DR: In this article, a well-dispersed graphene oxide (GO) and carbon nanotubes (CNTs) were successfully fabricated via in situ interfacial polymerization between two immiscible phases: organic phase assisted by poly(vinylpyrrolidone, PVP) surfactant containing adipoyl chloride with dispersion of GO and CNTs.

A Review of the Recent Advances in Cyclic Butylene Terephthalate Technology and its Composites
Tobias Abt,Miguel Sánchez-Soto +1 more
TL;DR: Cyclic butylene terephthalate (CBT®) oligomers are a relatively new class of material and are capable of polymerizing in an entropically driven ring-opening polymerization into high-molecular-weight polymerized CBT (pCBT) in very short times.

Electric Field Effect in Atomically Thin Carbon Films
Kostya S. Novoselov,Andre K. Geim,Sergey V. Morozov,Da Jiang,Y. Zhang,S. V. Dubonos,Irina V. Grigorieva,A. A. Firsov +7 more
TL;DR: Monocrystalline graphitic films are found to be a two-dimensional semimetal with a tiny overlap between valence and conductance bands and they exhibit a strong ambipolar electric field effect.

The rise of graphene
TL;DR: Owing to its unusual electronic spectrum, graphene has led to the emergence of a new paradigm of 'relativistic' condensed-matter physics, where quantum relativistic phenomena can now be mimicked and tested in table-top experiments.

TL;DR: It is shown that graphene grows in a self-limiting way on copper films as large-area sheets (one square centimeter) from methane through a chemical vapor deposition process, and graphene film transfer processes to arbitrary substrates showed electron mobilities as high as 4050 square centimeters per volt per second at room temperature.
