“…Considering that the agglomeration of graphene during the process will limit its functionality in improving the TE properties of hybrids, 78,79 herein, initially, the graphene was first ball milled with the MCAS powder to get good dispersion meanwhile wrapping the particles. The MCAS/x graphene powder (x = 10, 20, 30, 40, and 50 wt%) was loaded and sealed in a ball milling jar under an argon atmosphere (O 2 o 0.1 ppm) with a ball-topowder ratio of 32 : 3 and milled for 0.5 h. The resultant mixture was hybrid with PEDOT:PSS by a strategic process to overcome the crack, as depicted in Fig.…”

“…Alsalam et al [9] studied the effect of graphene nanoplates on the electrical properties of SnSe/GNPs composites (metal matrix composite (MMC)). The results showed that the graphene was able to keep its crystallinity at short milling times, but it exhibited agglomeration and poor dispersion within the matrix.…”

Graphene quantum dots are zero-dimensional nanoparticles that are used widely in advanced composite materials such as filtration membranes, adsorbent materials, optical devices, biomedical applications (especially biosensors), flame retardancy, and automotive, aerospace, agricultural and environmental applications. In this article, the mechanical properties (flexural strength, flexural strain and elastic modulus) of polymer-based nanocomposites will be investigated. The main novelty of the current work is the green synthesis of graphene quantum dots which were extracted from lemon juice. XRD and FTIR tests have been conducted to determine the composition of the prepared powder. The polyester resin and graphene quantum dots were mixed with different weight percentages (0.25%, 0.5% and 1% wt. graphene) and processed to fabricate nanocomposite samples. The mechanical properties of the prepared samples were measured according to the ASTM D790-17 standard testing method. The experimental results show that the strength increased from 80 MPa to about 112 MPa (40% increase in strength) by adding 0.25% wt. graphene quantum dots. The flexural modulus decreased from 2.70 GPa to 2.06 GPa by adding 1% wt. graphene content (23% decrease). The flexural strain increased considerably (up to 14.2%) by adding 1% wt. graphene quantum dots. Consequently, the ductility of the nanocomposites increased by adding green synthesized graphene quantum dots. The fracture behavior changed from brittle fracture mode to ductile fracture mode by adding the graphene quantum dots. Additionally, a flame retardancy test has been carried out by implementing the UL-94 test. The fabricated nanocomposites showed fire retardancy due to char barrier formation on the surface of the nanocomposites.
