Raman analysis of polypropylene fabric filled hummers method graphene oxide from regenerate carbon of waste tyre

Graphene oxide (GO), as a single-atomic-layer bonded into a honeycomb two-dimensional crystalline allotrope of carbon particles that frame hexagonal grid structure with an sp2 hybridization, has great optical, thermal, and mechanical properties. In this study, graphene oxide was synthesized from a waste carbon tyre using Hummer’s method. This is an environmentally friendly method that helps to turn waste into wealth. Raman spectrometer analysis was confirmed that graphene oxide was successfully synthesized from a waste carbon tyre. The peaks showed the D band and G band which at 1361 cm⁻¹ and 1596 cm⁻¹ and the intensity ratio of the D band relative to the G band (ID/IG) is 0.88. The morphological and structural of graphene obtained from waste carbon tyre were characterized by using scanning electron microscopy (SEM) with an electron diffraction X-ray spectrometer (EDX). The result shows that a few sheets stalked together on the surface with, bumping pieces, and coarse surface. The elemental composition of carbon (C) is higher than oxygen (O) element which showed a good composition of graphene oxide. Polypropylene fabric is used due to its non-absorbent properties for the basic medical masks and also does not absorb humidity which is very suitable to be apply as a face mask to prevent droplets and viruses in this research, the PP fabric face masks will be filled with GO to enhance the fabric face filter sheet. Produced GO powder was dispersed on a polypropylene fabric through the sonication method and tested for Raman analysis and SEM. SEM images show that GO successfully attached to the fabric. This result confirmed with Raman analysis with the appearance of D and G band on the PP-GO sample.
