Silicone rubber is widely used as an elastomer. This thesis investigates the fabrication and material properties of silicone rubber blended with some inexpensive fillers. The section of this thesis focuses on cornstarch-silicone rubber blends. In acetoxy cured silicone rubber, cornstarch has good compatibility and is able to blend well with the silicone resin. Samples were prepared by simple physical mixing. The crosslinking degree and other mechanical abilities can be investigated as a function of the weight percent of cornstarch and water. The second section of this thesis focuses on shape memory polymers. Shape memory polymers were fabricated by mixing acetoxy silicone with crystalline small molecules. The solid-liquid transition of the small molecule is able to generate reversible solid networks, which enable the shape memory effect. The shape memory effect properties tested as a function of the weight percent of the small molecule in samples. With increasing weight percent of the small molecule, the fixity is increased to ca. 99% and the recovery decreased to ca. 87%. Based on these tests, an optimum blend formulation is found, which shows the best shape memory performance can be found and repeatability through several test cycles. Due to the differences in the interaction degree between the small molecule and the silicone rubber, the choice of the small molecule is also an important factor to influence the shape memory effect.
