Moreover, subtle differences in the improvements of the tensile performance offered by GelMA/DbPE and GelMA/TbPE hydrogels over GelMA hydrogels were observed. While GelMA/DbPE hydrogels showed improved ultimate stress and extensibility in comparison to GelMA hydrogels, GelMA/TbPE hydrogels exhibited further improvements in ultimate stress in comparison with GelMA/DbPE hydrogels but with a loss in extensibility, such that their extensibility was comparable to GelMA hydrogels. These differences can again be ascribed to the PEC microstructure -disjointed micelles vs. interconnected networks -formed by DbPEs and TbPEs, respectively. The former is expected to exhibit higher restructurability but at the expense of lower stress threshold for restructuring, while the latter is expected to exhibit a larger threshold for network restructuring and lower restructurability owing to the interconnected microstructure. Overall, we surmise that the incorporation of bPEs into the covalent network overcame the low mechanical resilience of GelMA bioinks after photocrosslinking and facilitated their post-printing processability for applications that require relocation of the bioprinted constructs (e.g., transplantation).
