| Abstract |
With great concern of environmental threats, attempts have been made to reduce the consumption of zinc oxide (ZnO) in rubber products. This research aims at fabricating a new type of ZnO by depositing ZnO on microcrystalline cellulose (MCC) surface using an ultrasonic-assisted hydrothermal process. The concentration ratio of Zn(NO¬3)2 to NaOH is varied from 1:1 to 1:4. The obtained products, namely MCC-ZnO, are characterized by various techniques such as FESEM, FTIR, XRD, BET, and TGA. Results show that the amount of deposited ZnO and the specific surface area of MCC-ZnO increase continuously with increasing NaOH concentration. The MCC-ZnO (1:3) containing approximately 55.6 wt% of deposited ZnO is selected for investigating the curing efficiency in natural rubber (NR) and compared with the commercial ZnO (C-ZnO). Obviously, the state of cure progressively increases with increasing either MCC-ZnO or C-ZnO content. At the same content, MCC-ZnO exhibits a significantly higher crosslink density than C-ZnO leading to the superior elasticity and mechanical properties. This could be explained by the greater specific surface area and, thus, the higher reactivity of MCC-ZnO. Clearly, a considerably lower quantity of MCC-ZnO is required to attain a similar level of crosslink density or mechanical properties as compared to C-ZnO. |
