Abstract 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.

具有 MOF 的 3D 打印 ABS 过滤器的功能化以去除有毒气体

摘要 丙烯腈丁二烯苯乙烯 (ABS) 因其具有竞争力的热性能和机械性能而成为 3D 打印制造中应用最广泛的聚合物之一。最近,特别关注具有额外功能的新型 ABS 复合材料,例如在 VOC 去除领域。在此,我们报告了一种简单的协议,用于使用 MOF(金属有机框架)材料(ZIF-8)对 3D 打印 ABS 过滤器进行功能化,以实现有吸引力的气体过滤器的概念。所提出的合成策略包括在 ABS 网格上的 ZnO 的低温 ALD(原子层沉积),然后是 ZnO 到 ZIF-8 的水热转化,这两个步骤都在 60°C 下进行。以这种方式,该方法能够在不改变聚合物 ABS 载体稳定性的情况下有效生长 ZIF-8。
