Abstract
Magnetorheological elastomers (MRE) as intelligent materials are quite popularly used, both for indoor and outdoor applications that are often exposed to rain or sunlight depending on weather changes. In this case, the use of MRE material in outdoor use with exposure to freshwater and seawater needs further analysis. The analysis can then be used to evaluate the performance of the MRE. MRE specimens were molded in an isotropic state with vacuum treatment. Furthermore, the immersion treatment of the specimens was carried out for 6 weeks. In the 6-week immersion test, all specimens of material dissolution were dissolved, which was proven by a decrease in the percentage of absorption. The largest dissolution occurred in the 0%wt CIP heavy fraction specimen with seawater immersion treatment. In the hardness test of Durometer Shore A, both specimens of 0%wt CIP heavy fraction showed an increase in hardness, while in 70%wt CIP heavy fraction specimens, the opposite occurred. The greatest decrease occurred in specimens treated with freshwater immersion. The decrease in hardness can affect the stiffness of the material, resulting in a decrease in the dam** function. The FTIR test showed that there were new peaks found in seawater immersion specimens.
