It is crucial to develop 2W\u2010SMPs to achieve precise control of two\u2010way shape memory behavior without external forces and reveal their structure\u2010property relationships. In this study, dual\u2010crystalline phase crosslinked polymer networks based on poly(tetramethylene ether glycol) (PTMEG) and poly(\u03b5\u2010caprolactone) (PCL) are fabricated via thiol\u2010ene click reactions. The networks with two independent melting temperatures are gained by adjusting the ratio of the two segments and the two\u2010way shape memory is enabled using the temperature difference between the two phases. The effects of network composition, pre\u2010tensile strain, and actuation temperature on the two\u2010way shape memory properties are investigated and the two\u2010way shape memory mechanism of dual\u2010crystalline phase polymers is further elucidated. Among the various compositions of networks, PTMEG<jats:sup>8<\/jats:sup>\u2010PCL<jats:sup>2<\/jats:sup> exhibits the optimal two\u2010way shape memory properties, with the actuation strain of 24.25% and reversible strain of up to 10.35% at the actuation temperature and pre\u2010stretch strain of 45\u00a0\u00b0C and 15%, respectively, which is potential for soft robotics applications. It is believed that this work guides the design of semicrystalline networks with two\u2010way shape memory
