The three alternative molecular mechanisms of one-step dual-shape programming for AB polymer networks containing crystalline poly(ε-caprolactone) (PCL) and amorphous cyclohexylmethacrylate (PCHMA) phases are explored (see image). Depending on the temperature range selected either the PCHMA (a) or the PCL phases (b), or in fact both (c), determine solidity. In the latter case, (c), reheating results in a two-step recovery process demonstrating a triple-shape behavior.
