Abstract

This research was carried out to enhance the filterability of face masks with the addition of graphene oxide (GO). This research is about dispersing GO that synthesized from a recovered carbon from waste tire using Hummer’s meth-od on PP fabric. Polypropylene (PP) melt-blown fabric was used due to its non-absorbent properties for the basic medical masks. PP fabric coated GO is expected to improve the fabric face mask properties with the addition of GO. This is an environmentally friendly way that helps to turn waste into wealth. Recovered carbon GO powder was dispersed on a polypropylene fabric through the sonication method. Raman analysis peak proved that graphene oxide was successfully synthesized from a waste carbon tyre. The peaks showed the D band at 1367cm-1 and G band at 1593 cm-1 respectively. The intensity ratio of the D band relative to the G band (ID/IG) is 0.92.  SEM images show that GO particles stalked together on the surface of the sample structure, bumping pieces, and coarse surfaces. The elemental composition of carbon (C) is higher than oxygen (O) which showed a good composition of graphene oxide. While coated PP sample show that GO successfully attached to the fabric fiber and exhibited good air and water permeability as compared to control PP fabric. This result confirmed that graphene oxide possibly could be used as a filler to improve the filterability properties of fabric PP.
