This study reported the production of ENR/PVA/rGO composite by latex mixing method, which exhibited good chemical interaction, mechanical strength, and thermal stability, as well as high moisture and moisture absorption.
This work reported the production of epoxidized natural rubber (ENR)/poly (vinyl alcohol) (PVA)/graphene (rGO) composite by latex mixing method. The particle size of rGO was about 740 nm and negative charge value (-29 mV). After the incorporation of the rGO into the 80/20 ENR/PVA blend, the color turns into black. The toluene resistance was also improved owing to its chemical interaction between the ENR/PVA blend and rGO. The swelling ratio of the ENR/PVA blend was 7/7g/g while the swelling ratio of the ENR/PVA blend containing 1% w/w rGO was 3/3g/g. The lowest moisture content and moisture absorption were found when using 1g/g rGO. The maximum moisture and moisture absorption were found at ENR/PVA blend without rGO. After incorporation of rGO in the composite, the mechanical strength was enhanced jumping to the enforcement filler. The maximum tensile strength of ENR/PVA/1rGO was 17 MPa. The composite exhibits good thermal stability and the retention tensile strength of ENR/PVA/1rGO composite was about 80% at 24 h. After use, it easily decomposed in nature and the percentage of biodegradation was about 60%-75%.
