On page 5830, Z. G. Wu and co‐workers develop a novel approach to make poly(dimethylsiloxane) (PDMS)‐based elastomer soft, stretchable and sticky by introducing a small fraction of ethoxylated polyethylenimine (PEIE). Around the PEIE chains, the crosslinking of the elastomer is hindered and results in a gradient of crosslinking density, and hence heterogeneous crosslinked networks. These liquid‐like, loosely crosslinked domains in a highly crosslinked network enable higher compliance and larger elongation at break, accompanied by a surface that is highly adhesive to human skin.
