Abstract

Abstract:

Using polyimide as the precursor and TiO₂ sol as the dopant, hybrid carbon membranes were prepared through membrane formation and carbonization. The thermal property of precursor, the microscopic morphology, microstructure, surface functional groups and gas permeation of carbon membranes were characterized by thermogravimetric analysis, electron microscope, X-ray diffraction, infrared spectroscopy and permeation testing, respectively. The effects of TiO₂ sol dosage, permeation temperature and permeation pressure on the structure and property of carbon membranes were investigated. Results show that the incorporation of TiO₂ sol obviously improves the permeability and selectivity of final carbon membranes. For hybrid carbon membranes prepared by the precursor containing 10% TiO₂, the permeability can respectively reach to 1993.8 Barrer for H₂, 1555.6 Barrer for CO₂ and 266.9 Barrer for O₂, along with the selectivity of 93.6 for H₂/N₂, 73.0 for CO₂/N₂ and 12.5 for O₂/N₂.

Key words: membranes, gas, separation, polyimide, titanium dioxide

摘要：

以聚酰亚胺为前体，TiO₂溶胶为掺杂剂，经成膜和炭化制得杂化炭膜。采用热失重、电子显微镜、X-射线衍射、红外光谱和渗透法对前体的热性能、炭膜的微观形貌、微结构、表面官能团和气体分离性进行了表征。考察了TiO₂溶胶用量、渗透温度和渗透压力对炭膜的结构与性能影响。结果显示，掺杂TiO₂溶胶显著提高了最终炭膜渗透性和选择性；采用TiO₂溶胶量为10%前体所制备的杂化炭膜对H₂、CO₂、O₂渗透性分别为1993.8、1555.6、266.9 Barrer，同时H₂/N₂、CO₂/N₂、O₂/N₂选择性分别为93.6、73.0、12.5。
