Abstract:

This work presents the application of the methodology for the sensitization of surface
acoustic wave-based sensors (SAW), developed in the first part of this work. The strategy of the
method is the obtention of sensing layers with tailored chemical environments by taking advantage of
the wide variety of chemical composition of the organic polymers, which have been used as sensing
polymers, and combining them with polyurethane (PU) to form polymeric composites that show
enhanced properties as sensing materials for the SAW sensor technology. In the first part of this
work, the ultrasonic and adhesion characterization was correlated to the sensor responses of PU-
polybutylmethacrylate (PBMA) composites of different relative concentrations of the sensing polymer
(PBMA) and PU. The resulting coating layers obtained with the PU polymer composites improved
the chemical and mechanical properties of the sensing layer without interfering with the quality
of their sensor responses in comparison to those with the pristine polymer as the sensing material.
In this second part of this work, three new polyurethane polymeric composites were analyzed.
