doi:10.19398/j.att.202106067

Abstract

Abstract: In order to prepare an air filter with excellent filtration performance, taking Co(NO₃)₂·6H₂O as a Co source, using the simple hydrothermal synthesis method, Co(CO₃)_0.5(OH)·0.11H₂O nanoneedle array(cobalt-based nanoneedle array) were grown vertically on the surface of polyester(PET) fibers, and then ZIF-67 crystals with electrostatic adsorption were in-situ grown on the surface of cobalt-based nanoneedle array by vapor deposition. The morphology, structure and chemical composition of the prepared fibrous filter were analyzed by SEM, TEM, FTIR, XRD and other characterization methods. The experiment results showed that when the vapor deposition time was 24 h, the compound fabric’s filtration efficiency was the optimal(PM_2.5: 90.91%, PM₁₀: 92.51%) at an airflow velocity of 0.2 m/s, with the maximum filter quality factor of 0.038 Pa^-1. Further recycling performance test indicated that it maintained a PM_2.5 air filtration efficiency of over 85% after 7 cycles of use.

摘要： 为了制备具有优良过滤性能的空气过滤器,采用简便的水热合成制备法,使用Co(NO₃)₂·6H₂O作为Co源,在聚酯纤维表面垂直生长Co(CO₃)_0.5(OH)·0.11H₂O纳米针阵列(钴基纳米针阵列),并通过气相沉积的方法在钴基纳米针阵列表面原位生长具有静电吸附作用的ZIF-67晶体。通过SEM、TEM、FTIR、XRD等表征方法对制备的纤维过滤器的形貌结构以及化学构成进行分析,结果表明:气相沉积时间为24 h时的复合织物样品在0.2 m/s的气流速度下具有最佳的过滤效率(PM_2.5:90.91%,PM₁₀:92.51%)以及最大的过滤品质因数(0.038 Pa^-1)。循环使用性能测试显示,在7个循环使用情况下其还能保持85%以上的PM_2.5的空气过滤效率。
