Stress transfer at the nanoscale on graphene ribbons of regular geometry

Abstract

Experimental and theoretical investigation of true axial stress transfer on regular-exfoliated-graphene micro-ribbons which are aligned to the loading direction.

Comprehensive Enhancement in Thermomechanical Performance of Melt-Extruded PEEK Filaments by Graphene Incorporation

“…This is due to the improved dispersion of the GnP fillers inside the PEEK matrix and the formation of a strong interface between fillers and matrix through hydrogen bonding and π-π* interactions. These factors contribute to optimizing the stress transfer from the PEEK matrix to the graphene fillers, inducing a strong reinforcing action of the GnP fillers [55][56][57]. The improvement in elongation at break (31%) and tensile strength (34%) at 1 wt.% of GnP loading demonstrated significantly better results than the previous reports [6,58,59].…”

Growth andin situcharacterization of 2D materials by chemical vapour deposition on liquid metal catalysts: a review

“…170 The Raman peak positions, intensities and full widths at half maxima (FWHM) can directly indicate the layer number, 171 crystalline orientation, 172 stacking configuration, 173 defect nature 174,175 and applied strain. 4,5,170,171 Hence, it constitutes an indispensable characterization tool to uncover the overall condition of 2DMs. Therefore, implementation of such a robust technique for the direct assurance of quality in the produced 2D sheets by CVD could lead to ISO validated growth recipes.…”

“…The isolation of graphene by Konstantin Novoselov and Andre Geim in 2004, 1 has led to the advent of a new class of materials with extraordinary properties [2][3][4] that have since been classified as 2D materials (2DMs). From extraordinary mechan-ical strength 2,5 and flexibility to outstanding thermal and electrical conductivity 3,6,7 paired with transparency, 8 these extraordinary materials propelled the enthusiasm for discovering new standards. A variety of methods have been employed to produce 2DMs 9,10 with different results in attained quality and quantity.…”

Graphene and related materials in hierarchical fiber composites: Production techniques and key industrial benefits

“…We have undertaken extensive studies of stress transfer at composites interfaces at the nanoscale using Raman spectroscopy [32,58,62] [ [63][64][65]. A strong interaction allows to have a shorter "critical length" of the flakes actively reinforcing the composite [32,66].…”
