摘要

摘要: 针对疫情防控常态化背景下，探究一种具有多功能性的还原氧化石墨烯复合过滤材料。对还原氧化石墨烯（rGO）复合功能性过滤材料与常用驻极体过滤材料（PTFE）进行过滤特性、抗菌等性能对比实验分析，结果表明：在首次实验时，rGO滤料的过滤效率与滤速的变化呈正相关，PTFE滤料的过滤效率的趋势相反，且过滤效率整体上优于rGO滤料。但后续实验中在0.25 m/s滤速下，rGO滤料对PM_2.5的过滤效率比PTFE滤料高3.6百分点，但rGO滤料的过滤阻力约为PTFE滤料的2倍。当过滤风速为0.05 m/s时，相比于PTFE滤料，rGO滤料容尘量约为其7倍。此外发现由于rGO具有包裹与纳米刀作用，使得rGO滤料同时兼有一定抗菌抑菌性。该成果为后疫情时代中空气净化器的选择以及rGO滤料性能的提高提供参考依据，也为后续的复合滤料研究与应用提供了新思路。

Abstract: It is necessary to research and develop a multifunctional composite filter material under the current context of regular epidemic prevention and control. Reduced graphene oxide (rGO) composite functional filter material and the electret air filtration material (PTFE) were chosen for the experimental study. Tests on the filtration characteristics and antibacterial properties and other properties were conducted. Results showed that at the beginning of the filtration experiment, the filtration efficiency of rGO filter material was positively correlated with the change in filtration rate, while the trend of the filtration efficiency of PTFE filter material was opposite, and the filtration efficiency was better than that of rGO filter material overall. In the subsequent experiments, the filtration efficiency of rGO filter material was generally higher than that of PTFE filter material, but the filtration resistance of rGO filter material was about twice that of PTFE filter material. The dust capacity of rGO filter material was far greater than that of PTFE filter material at the wind velocity of 0.05 m/s. In addition, it was found that rGO filter media also had certain antibacterial and bacteriostatic properties. This study provides a reference for the selection of air purifiers and improvement of rGO filter material performance in the post-pandemic era, which also provides a new idea for the subsequent research of composite filter material.
