Although mech. robust polymer materials had not been thought to self-heal, we recently found that poly(ether thiourea) PTUEG3, which is a glassy polymer with high mech. strength, self-heals even at ambient temperatures This finding updated the above preconception. Nevertheless, it should also be noted that PTUEG3, under high humidity, absorbs water and is plasticized to lose its mech. strength. Humidity-induced plasticization is a general problem for polymers with polar groups. Herein, we report that PTUEG3, if designed by copolymerization to contain only 10 mol % of a dicyclohexylmethane (Cy2M) thiourea unit (TUCy2M), serves as a humidity-tolerant, mech. robust polymer material that can self-heal at ambient temperatures This copolymer contained, in its ether thiourea (TUEG3)-rich domain, a humidity-tolerant, noncovalently cross-linked 3D network with mech. robustness formed by stacking of the Cy2M group. The present work provides a promising design strategy for mech. robust, self-healable polymers usable under high humidity.
