Stretchable electronics and optics, soft transducers, robotics and biomedical devices are some of the most rapidly developing fields of science. A multitude of recently reported soft devices employs commercial silicone elastomers as the stretchable component with Sylgard 184 being the most frequently used. Although this silicone composition has multiple favorable properties it suffers from several shortcomings with respect to some applications, e.g. high Young’s modulus and low strain at break. This introduces some serious limitations to functionality and performance of some of the developed products. With over a decade of experience working with and optimizing silicone elastomers in close collaboration with various research centers and major silicone producers, our group decided to create a “silicone elastomer map” that is intended to provide guidelines on how to formulate silicone elastomers based on simple mixing of commercially available silicone elastomer products. This allows scientists without access to chemical laboratories – or without the desire to synthesize their own elastomers – to achieve a broader range of properties than what the commercial products offer Our study will serve as a platform allowing the users to design and fabricate silicone elastomers with specific mechanical, electrical and optical properties. We will explain why a simple change of the mixing ratio of commercial compositions aimed at obtaining softer silicones is not a viable path if reliable elastomers are sought.
