Gas Analysis of Magnetorheological Elastomer During Vacuum Degassing

Abstract

Research conducted in a vacuum requires high accuracy, but multiple vibrational and shock disturbing effects adversely affect the results. To increase the accuracy, it is possible to install a vibration isolation system in a vacuum chamber. One of the promising areas of active vibration isolation is the use of intelligent materials in them, including magnetorheological elastomer (MRE). Since most studies need to be carried out in a high and ultra-high vacuum environment, it is necessary to know the degree of influence of the MRE gas release on the quality of the operation environment. Thus, the aim of the work was to analyze the spectrum of released gases during degassing of the polymer (MRE) in vacuum at room and elevated temperatures. It was found that increased gas evolution from the studied polymer sample with increasing temperature does not allow to achieve high vacuum (1,7 · 10−3 Torr). We also identified that gases with the highest partial pressures are part of the atmospheric air; there are other gases not analyzed that significantly affect the total pressure (have a pressure of the order of 10−3 – 10−4 Torr).
