Reinventing Butyl Rubber for Stretchable Electronics

Abstract: The development of stretchable electronic devices that are soft and conformable has relied heavily on a single material—polydimethylsiloxane—as the elastomeric substrate. Although polydimethylsiloxane has a number of advantageous characteristics, its high gas permeability is detrimental to stretchable devices that use materials sensitive to oxygen and water vapor, such as organic semiconductors and oxidizable metals. Failing to protect these materials from atmosphere‐induced decomposition leads to premature de… Show more

“…Future work should also consider elastomer properties such as gas permeability to ensure long lifetimes for sensitive active materials. 170 Polymer blends with good miscibility may improve both electrical and mechanical performance through stronger intermolecular interactions but further research is required. In-depth studies of morphology and phase separation will help scientists design materials of optimal electrical and mechanical properties from individual polymer properties.…”

“…32,42 Butyl rubbers have long been used to make inner linings of tires 42 , medical gloves 43 , and drug-eluting stents 44 . Recently, butyl rubbers have been used as hermetic seals for stretchable electronics [45][46] . Despite its relatively low permeability, butyl rubber is still too permeable to prevent dehydration of hydrogels at the scale of a typical textile fiber; See Table 1 later in the paper.…”

“…[172] Stretchable transparent packaging materials, such as PDMS, PU, or butyl rubber, are commercially available. [173] Therefore, the development of stretchable transparent supercapacitors is mainly determined by two components (Figure 9b), STEC and STIC, which play the role of the electrode materials with high conductivity and the electrolyte with separator function, respectively.…”
