Resumen
Acrylonitrile butadiene styrene (ABS) is one of the most extensively used
polymer in 3D printing manufacturing due to its competitive thermal and mechanical
properties. Recently, a special attention has been devoted to novel ABS composites
featuring extra functionalities e.g. in the area of VOC removal. Herein, we report on a

Acrylonitrile butadiene styrene (ABS) is one of the most extensively used
polymer in 3D printing manufacturing due to its competitive thermal and mechanical
properties. Recently, a special attention has been devoted to novel ABS composites
featuring extra functionalities e.g. in the area of VOC removal. Herein, we report on a
facile protocol for the functionalization of 3D printed ABS filters with a MOF (Metal-
Organic Framework) material (ZIF-8) targeting the conception of attractive gas filters.
The proposed synthesis strategy consists in low temperature ALD (Atomic Layer
Deposition) of ZnO on the ABS grid followed by the hydrothermal conversion of ZnO
to ZIF-8, both steps being conducted at 60 °C. In such way, the method enables an
effective growth of ZIF-8 without altering the stability of the polymeric ABS support.
The as-fabricated ABS/ZIF-8 filters offer a promising adsorption behaviour for
dimethyl methylphosphonate (~20.4 mg of DMMP per gram of ZIF-8), thus proving
their potential for toxic gas capture applications. [--]
