a Chemical structures of PDMS elastomers modified with amines. b Photograph of a CL–M5 sheet that is colorless and transparent. c Compression behavior of a block of CL–M5 in N2 and CO2 gases. CL–M5 is extremely toughened with CO2 gas while it is brittle in a N2 environment. See Supplementary Movie 3 and Supplementary Movie 4 in detail.
