This paper reports on the nanohardness properties of copper-based metal-organic framework (MOF-199) synthesized in-house by facile method fab- ricated into bulk adsorbents by binder-less compression and into thin-film by screen-printing. 13 mm diameter bulk adsorbents were prepared for four different materials 1) MOF-199, 2) zeolite 13X, 3) activated carbon (AC) and 4) hybrid MOF-199: AC (1:1). In addition, MOF-199 was fabricated into thin-film on soda- lime glass substrates using screen-printing method. Polyvinyl acetate (PVA) was replaced with environmental-friendly binder materials of gum Arabic (gA) and palm oil based fatty alcohol (PODFA) with 8 carbon chain of decyl alcohol. X-ray diffraction (XRD) analyses of MOF-199 fabricated both by binder-less compres- sion and screen-printing exhibited a prominent peak at ca. 2θ = 11.7° attributable to (222) reflection plane of octahedral crystal structure suggesting that morphol- ogy and crystallinity were retained after fabrication processes. The octahedral morphology at ca. 1 μm and ca. 2 μm were observed for screen-printed thin film suggesting that the structure was preserved. Reduced modulus (R*) for pure MOF-199 and hybrid MOF-199:AC bulk adsorbents were at ca. 2.818 GPa and 0.002 GPa, respectively suggesting that hybrid adsorbent was not suitable for appli- cations due to lack of hardness. Reduced modulus value of MOF-199 thin-film were higher at ca. 6.577 GPa (gA), 3.539 GPa (PVA), and 0.816 GPa (PODFA), respectively.
