在工业化迅猛发展的今天, 环境污染问题日益突出, 有毒有害气体的危害与日俱增, 给人类的工业生产和日常生活安全带来了极大的威胁。面对这些威胁, 为了开发绿色环保、成本低廉以及便于获取的气敏传感材料。采用热解碳化法制备了碱菀基碳微米管(CMTs), 然后使用表面活性剂(洗衣粉溶液)对其进行了非共价修饰, 对比研究了修饰前后其气敏性能的变化。结果表明:非共价修饰后, CMTs的气敏性能得到了非常显著的增强。这为低成本、高性能气敏传感材料的制备提供了新的路径。
With the rapid development of industrialization today, the problem of environmental pollution is becoming more and more prominent, and the harm of toxic and harmful gases is increasing day by day, which brings great threat to the safety of human industrial production and daily life.In the face of these threats, in order to develop green and environmentally friendly, low-cost as well as easily accessible gas-sensing materials, alkali-based carbon microtubes (CMTs) were prepared by pyrolysis carbonization, and then non-covalently modified with surfactant (detergent solution).The changes in gas sensing performance before and after modification were compared and studied.The results showed that the gas sensing properties of CMTs were significantly enhanced after non-covalent modification, providing a new route for the preparation of low-cost and high-performance gas sensing materials.
