报告内容摘要：
With the reversible cross-linking feature, vitrimer-like polymers can be utilized to achieve some special functions that are difficult to be realized by conventional polymers, which are either thermo-plastic or thermoset. In this speech, a commercial polyurethane (PU) based polymer is presented to show how we can systematically characterize the vitrimer-like behavior of a polymer based on the shape memory effect (SME). Then, a few different approaches are proposed to either macroscopically or microscopically reshape (both outside and inside) vitrimer-like polymers and their composites. Based on the characterized shape memory performance of this commercial vitrimer-like polymer, a couple of ways for permanent and/or temporary reshaping are demonstrated. It is concluded that the vitrimer-like behaviour adds in an addition dimension not only to reshape our design, but also to bring forward many potential applications, which traditional polymers, either thermo-plastic or thermoset, have some difficulties to deal with.
