Mechanical Properties of Green Synthesized Graphene Nano-Composite Samples

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