Sugimoto, Kanta published the artcileVersatile tensile and fracture behaviors of dual crosslinked elastomers by postpreparation photo tuning of local crosslink density, COA of Formula: C5H12O2, the publication is Polymer (2021), 124089, database is CAplus.
This study demonstrates the postpreparation easy tuning of the Young’s modulus of elastomers by using polyesters bearing thermal and photo crosslinkable groups. In the first crosslinking step, only thermoreactive groups form crosslinks, resulting in a highly deformable soft elastomer. In the second step, photoreactive groups are crosslinked by UV irradiation, and controlling the UV irradiation time can tune the crosslink d., resulting in modulus tuning over two orders of magnitude at room temperature The use of photo reaction enables precise modulus patterning using photomasks with a series of slits. In horizontally patterned samples, the dually crosslinked stiff section shows negligible deformation, whereas large elongation is observed selectively in the single crosslinked soft sections. In vertically patterned samples, interestingly, crack propagation and complete fracture are significantly suppressed, compared with the fully dually crosslinked sample. The present data can thus provide important insight for developing new methodologies for controlling the tensile and fracture behavior of elastomers.
