Relief of Residual Stress in Bulk Thermosets in the Glassy State by Local Bond Exchange

Abstract

Front Cover: Residual stresses in thermosets are hardly relieved in the glassy state. In article 2300735, however, Kangning Wu, Chenhui Cui, Jianying Li, and co-workers demonstrate incredible residual stress reduction in polythiourethane incorporated with dynamic covalent bonds by simply annealing below the glass transition temperature (Tg), during which excellent properties gifted by the highly cross-linked network of thermosets are well maintained.
