Modification of Footwear PVC Outsoles into Graphene Oxide-Based PVC (PVC/GO) Soling Composites for the Enhancement of Better Physical Properties

Outsole is a crucial component of shoe’s bottom that directly contacts the ground. Comfort and durability are most expected characteristics outsoles. Various nanocomposites utilized to increase thermal stability, light weightiness, microporosity, polymeric materials. In this research, PVC soling composites were prepared using synthesized graphene oxide (GO) from modified Hummer method. The goal improve physical properties like stability or durability, lightweight, tensile strength, hardness. GO content in developed ranged 0.1% 0.4% by colloidal blending FTIR, TGA, XRD, SEM characterized GO/PVC composites. presence functional groups C=C, C-O-C, -C=O, -OH was confirmed FTIR spectra GO, while oxygen-holding layered structure caused separation interlayer space grow 0.34 nm 0.86 nm, according XRD data. results revealed layers uniformly distributed matrix TGA exhibited percentage mass loss for 81.96% at 800 °C it decreased continuously with an respectively. analysis showed homogeneous composite significantly porous surface morphology. Proportional improvement strength hardness GO-based materials increased proportion density proportion, making outsole lightweight durable. Finally, suggest can mechanical microporosity soles, best performance found PVC/GO-0.4%
