Phase separation and crystallization in high hard block content polyurethane thin films

Abstract:

Following studies of bulk behavior, the morphological evolution in thin films of linear TPUs with a high content of hard segment (HS) (from 70 to 100 wt %) on annealing is investigated. In contrast to melt-quenched bulk samples, a mixed phase was obtained for as-spin-cast films, and then, on annealing, a phase-separated mesophase domain, as previously observed by scattering and TEM in bulk samples, was observed by AFM to form directly from the mixed phase. In addition to this overall phase be...
