摘要：
The development of biobased reshapable and repairablevitrimershas received extensive attention due to the growing focus on an environmentallyfriendly society. Therefore, the objective of this research was tosynthesize sustainable polymers with an environmentally friendly strategycombining the benefits of renewable resources, UV curing, and vitrimers.Two biobased monomers, glycerol 1,3-diglycerolate diacrylate and tetrahydrofurfurylmethacrylate, were chosen for the preparation of UV-curable resinsand tested by real-time photorheometry and RT-FTIR spectroscopy todetermine their suitability for digital light processing (DLP) 3Dprinting. DLP 3D-printed polymer showed shape memory, weldability,and repairability capabilities by triggering the dynamic transesterificationprocess at high temperatures. The vitrimer with a weight ratio of60:40 of glycerol 1,3-diglycerolate diacrylate and tetrahydrofurfurylmethacrylate showed shape memory properties with a recovery ratioof 100% and a 7-fold improved tensile strength compared to the originalsample, confirming efficient weldability and repairability.
