Three-phase composite based on Chewing gum-SBR waste and quartz particles

ABSTRACT

The high consumption of industrialized products and their disposal produce large quantities of solid waste, of which the principal constituents are polymeric materials. Among these, the butadiene-styrene rubbers deserve special mention. This material is used in various industries, including food, for the production of chewing gum. Thus, the recycling of these materials must always be researched, mainly seeking new applications. Therefore, this work used residual rubber (BP) as a matrix for quartz crystals. The materials prepared were studied by several techniques, such as Thermogravimetric Analysis (TGA) and Fourier Transform Infrared Spectroscopy (FTIR). Besides, the materials also had their electrical properties measured. Capacitance, electric field, resistivity and current density measurements were performed. Among the tested materials, the composite loaded with 44.4% of quartz presented the most linear and intense response of electric charge variation as a function of the applied pressure. Therefore, the obtained results allow proving that were accomplished materials with the potential of application in the field of capacitive pressure sensors.
