Abstract
Nanocomposite made by blending nano-montmorillonite (MMT) and Silicon Rubber (SR) for mechanical and tribological performance is explored in this work. Different configurations of MMT/SR nanocomposite, with 0, 0.5, 2 and 5 wt % of MMT are manufactured by two roll mixing methods. Noticeable improvement in the mechanical and tribological performance is observed, which is also justified by a morphological study of fractured and wear surfaces through SEM. Two percent of MMT loading is found to be the optimum content that shows excellent performance compared to other compositions. The performance improvement can be linked to the good interfacial interaction between the MMT and SR. Statistical modeling through ANOVA is carried out for tribological performance, which reveals the influence of load on the coefficient of friction (COF) and the influence of sliding distance on the wear rate.
Highlights
Synthetic elastomers like silicone rubber (SR) are commonly found in application in industries such as aerospace, medical, and electronics
Silicon rubber properties can be radically improved by adding nanofillers like carbon black (CB), carbon nanotube (CNT), graphite, nano Ce O2 [3,4]
Similar works can be found in literature that show the influence of graphene oxide addition on resistivity and dielectric constant [5], thermal stability with the function of iron oxide and CNT filling [6], and tribological study [7] of various nanocomposites performed on the SR composite
Summary
Synthetic elastomers like silicone rubber (SR) are commonly found in application in industries such as aerospace, medical, and electronics. Similar works can be found in literature that show the influence of graphene oxide addition on resistivity and dielectric constant [5], thermal stability with the function of iron oxide and CNT filling [6], and tribological study [7] of various nanocomposites performed on the SR composite. All of these studies have revealed the usefulness of SR for different engineering applications.
