a RLMNPs were prepared in different liquid resins using N-hydroxyethyl acrylamide (HEAAm), 2-hydroxyethyl acrylate (HEAm), tert-butyl acrylate (TBAm), and N, N-dimethyl acrylamide (DMAm) as main monomers, respectively. l, w, and t mean the length, width, and thickness of the LMPCs, respectively; (b) TEM photographs of RLMNPs in liquid resins with different monomers. The experiments were repeated independently three times with similar results; (c) Intensity-based size distribution histograms of RLMNPs in liquid resins with different monomers measured by DLS. The size of RLMNPs was measured immediately after sonication; (d) Mechanical properties of 3D-printed LMPCs using different monomers and the storage modulus of 3D-printed objects was determined at 20 °C. Bars in (d) represent means ± SD (n = 3 independent 3D-printed samples). The p-value ranges provided in the graphs were obtained using one-way ANOVA.
