N2 - Functionalized, porous polydimethylsiloxane (PDMS) structures have been a topic of growing interest in the polymer foaming community for their unique properties. PDMS has been used in piezoelectric applications due to its high elasticity and ability to withstand repeated deformation. Under the same conditions, PDMS foams can deform more than solid bulk samples, making them better candidates for energy harvesting and sensing applications. In this paper, PDMS foam samples were prepared using sugar scaffolding methods with three different types of sugar. This process yielded open pore structures at varying densities and pore sizes. Our PDMS foams were functionalized with zinc oxide nanoparticles and carbon nanotubes (CNTs). The mechanical characterization revealed that the foamed structures of the granulated sugar had the optimal results versus the brown and ultrafine sugar samples. Additionally, the electrical output in the granulated sugar foamed samples was higher than in the brown and ultrafine sugar samples. Our results demonstrate that PDMS foams are a promising material that can be used in future piezoelectric applications.
