Processing And Mechanical Characterization Of Polyurea Aerogels, Jared M. Loebs
Processing And Mechanical Characterization Of Polyurea Aerogels, Jared M. Loebs
Masters Theses
"The use of aerogels historically has been limited to extreme cases largely in part to the nature of their mechanical properties. Until recently many aerogels produced have been brittle and weak, though looking at their specific strength would suggest otherwise. This thesis outlines the processing and major mechanical properties of a relatively new type of aerogel, polyurea aerogel, that shows promise in a variety of fields including structures.
Processing polyurea aerogel begins with a liquid solution that solidifies to form a solid gel filled with liquid that is later removed by supercritical drying. Once dry, polyurea aerogels are difficult to …
