Mechanical characterization of the DLP printed ACMO-based composites. (a) Stress-strain curves of printed dog-bone samples with various MUA loadings (0, 20, 40, and 60 wt% of MUA) tested till failure. (b) Schematic illustration of the role of soft segments (MUA along with hydrogen and ionic bonding) in the sample under tension. (c) Elastic modulus, (d) ultimate tensile strength, (e) elongation at break, and (f) toughness of the dog-bone samples with different MUA loadings. Scanning electron microscopy (SEM) images of the fractured face of the (g) neat ACMO samples, (h) ACMO/MUA composites with 20 wt% MUA, and (i) ACMO/MUA composites with 40 wt% MUA.
