WebCraze healing will proceed as follows; initially the highly oriented chains in the craze fibrils will retract, and at the same time stress on craze surface will decrease owing to viscoelastic relaxation of the bulk polymer. WebAug 5, 2024 · There is no denying that polymer chain mobility is a key factor to facilitate self-healing. In addition, it is worth noting that whereas craze healing occurs at temperatures above and below the glass transition temperature (Tg), crack healing happens only at or above the Tg [18].
