“…Among numerous nanofillers [32][33][34][35], vermiculite (VMT), silver (Ag), and graphene oxide (GO) nanofillers are operational in improving the physical properties and crystallization of PLA owing to their excellent physical properties, comprising their high aspect ratio and imperative surface area [36][37][38][39][40].…”

The structural, thermal, and mechanical properties of unreinforced and reinforced polylactic acid (PLA) were investigated. The PLA was a biopolymer that was reinforced with four fillers (i.e., graphene oxide (GO) and silver (Ag); vermiculite (VMT) and silver (Ag); and two organically modified vermiculites). The processing technique for the production of the composite materials were carefully planned. The PLA nanocomposites were investigated by examining their morphological aspects, changes in PLA phases and transitions and, most importantly, the effect on certain final properties. X-ray diffraction and differential scanning calorimetry (DSC) analysis indicated that the sample was completely amorphous. Thermogravimetric analysis (TGA) results indicated that the presence of reinforcing particles in the PLA matrix did not affect the thermal degradation of these composites. Furthermore, the local mechanical properties were investigated using the microindentation method to evaluate the effect of different nanofillers. Scanning electron microscopy (SEM) and a VHX-500 optical digital microscope (Keyence International, Mechelen, Belgium) were also used to examine the surface morphology of the PLA polymer composites. These results can help to select suitable fillers to enhance the PLA performance of biopolymers.

“…To our knowledge, and after analysis of the bibliographic references, there is no work dedicated to quantifying the performances of a matrix doped by nanofillers under 3-point bending type solicitations. Nevertheless, this work constitutes an exciting database for scientists and industrialists and complements our work on nanocomposites and understanding their mechanical responses and damage kinetics under static and dynamic loads [39][40][41][42][43][44][45][46][47][48].…”

In this paper, we will be interested in bending tests on a polymer matrix reinforced with graphene nanofillers. The mechanical behaviour and the damage kinetics were determined. The samples were made using controlled dispersions of graphene nanoplatelets (GNP) in EPON 862 matrix. Various samples with different contents of GNP were made (0%, 0.5%, 1%, 2.5%, 5% and 10% by weight). Mechanical properties such as maximum stress, strain at break and Young's modulus were determined. After each test, the fracture surfaces were characterised using optical microscopy (OP) and scanning electron microscopy (SEM). Experimental results show that the fracture toughness of the GNP/epoxy-based nanocomposites decreases with an increasing percentage of nanofillers. The flexural strength of the samples with 10 wt% of graphene significantly decreased compared to neat epoxy. Based on Stress-Strain data and the analysis of the fracture surface, it seems that graphene nanoplatelets show an impact on the mechanical behaviour and the kinetics of the damage. The influences of the weight percentage of GNP on the EPON matrix properties and the performance of the nanocomposites are discussed. In addition, the evolution of bending performance and damage kinetics with graphene content was obtained and analysed.
