Silicone rubbers for dielectric elastomers with improved dielectric and mechanical properties as a result of substituting silica with titanium dioxide

International Journal of Smart and Nano Materials, 2015
One prominent method of modifying the properties of dielectric elastomers (DEs) is by adding suitable metal oxide fillers. However, almost all commercially available silicone elastomers are already heavily filled with silica to reinforce the otherwise ...

Starch/Silicone Elastomers and Foams

Sustainability, 2023
While the beneficial physical properties of silicone polymers are exploited in many sustainable applications, the high energy requirement for their synthesis compromises to a degree their sustainability. We report a strategy to mitigate this issue by filling the silicone with inexpensive and renewable starch.

Fatigue Analysis of Flexible Joint Elastomers Combining Ogden Second-Order Constitutive Model with Cracking Energy Density

Aerospace, 2023
As the core component of the flexible nozzle on solid rocket motors, the flexible joint relies on the shear deformation of its silicone rubber elastomers to achieve a large vector angle, and the joint is prone to fatigue failure when working under high ...
