Five new coordination polymers, [Cu3(imp)4(sip)2]•2H2O (1), {[Cu3(imp)6(H2O)2.5](sip)2}•15H2O (2), [Cu2(imp)(sip)(OH)(CH3OH)]•CH3OH (3), {[Cu3(timp)6(H2O)4](sip)2}•15H2O (4), and [Cu3 (timp)3(sip)2(H2O)2]•4H2O (5) were synthesized via solvothermal reactions using copper(II) mixed ligands, including 5-sulfoisophthalate ions, (sip) 1,3-bis(1H-imidazol-1-yl)propane (imp), 1,4-bis(1H-imidazol-1-yl)butane (timp). Characterization techniques, FT-IR spectroscopy, thermal analysis, single-crystal X-ray diffraction, confirmed the successful formation of these polymers. Single-crystal diffraction revealed that compounds 1, 4, 5 crystallize in space group P1¯, while 2 3 P21/c Pnnm, respectively. All polymers include multiple copper ions with different geometries. In 2, 3, have octahedral trigonal bipyramidal geometries, whereas contains square pyramidal planar The behavior all was investigated under a nitrogen atmosphere. Decomposition occurs within 150–300 °C range, beginning desolvation. activation energies for this process measured, ranging from 32 to 89 kJ mol–1, providing valuable insights into compounds' properties. Notably, desolvation studies indicated similar properties 5, which exhibit single-step desolvation, 4 dehydrate two distinct steps.

Low-carbon indoor humidity regulation via 3D-printed superhygroscopic building components

Nature Communications, Год журнала: 2025, Номер 16(1)

Опубликована: Янв. 10, 2025

Indoor humidity can significantly impact our comfort and well-being, often leading to the use of mechanical systems for its management. However, these result in substantial carbon emissions energy precarity. This study offers an alternative: using low-carbon materials that naturally buffer moisture passively regulate indoor humidity. A geopolymer composite incorporating industrial waste is implemented via binder jet 3D printing technology. The superhygroscopic nature material, combined with optimal geometry 3D-printed components, unlocks remarkable potential passive regulation, achieving a buffering value over 14 g·m⁻²·%RH⁻¹. 3D-printed, tiles surface finishing library hosting 15 people was shown improve annual hygrometric by up 85%, performance inconceivable conventional techniques. Additionally, environmental lower than dehumidification system. paves way merging highly hygroscopic, advanced manufacturing techniques levels reduce dependency on systems. In this study, were used regulation. With g·m⁻²·%RH⁻¹, case improved users' 85% much footprint
