Fig. 3: 3D printing and crystallization of multiferroic molecular heterogeneous solid.
a Schematic diagram for manufacturing multiferroic composite (Lattice structure) by the SLA method. The digital projection printing setup (Supplementary Fig. 4) was utilized to project dynamic digital masks on the photocurable polymer composite solution. The UV light used has a wavelength of 385 nm and the control of image projection was achieved through a dynamic micromirror device. b Room-temperature polarization vs electric field (P-E) loop for molecular ferroelectric ImClO4 at 5 Hz. Room-temperature M-H loop for molecular magnetic MA. c Time dependence of resistance measurement during the crystallization process. d Optical images for 3D printed IM-VH with different complex geometric structures (Schwarz primitive structure, lattice structure and minimal surface Structures, 25 × 25 × 25 mm3). e Room-temperature in situ XRD measurement during the crystallization process. Insets show the optical images for the printed sample during the crystallization process. f SEM image for IM-VH, bright area indicates the PEGDA scaffold, and the dark area represents IM-VH. EDS mapping for V and Cl elements. g Room-temperature Raman spectra for IM-VH, IM, and VH. h Schematic diagram for the interface between IM and VH.
