Quaternary ammonium‐silica (QA‐SiO<jats:sub>1.5</jats:sub>) xerogel powders/films were fabricated via sol‐gel processing and their thermal stability was systematically studied using thermogravimetric mass spectrometer, Fourier transform infrared, energy dispersive spectroscopy, and positron annihilation lifetime spectroscopy analysis. CO<jats:sub>2</jats:sub> sorption performances of QA‐SiO<jats:sub>1.5</jats:sub> derived xerogel powders were quantitatively compared after assigning their relevant parameters to a dual‐mode sorption model. The gas permeation performances of membranes derived from QA‐SiO<jats:sub>1.5</jats:sub> were evaluated in terms of kinetic diameter and temperature dependence of gas permeance, and activation energy (E<jats:sub>p</jats:sub>) required for gas permeation. The results indicate that liberation of the CH<jats:sub>3</jats:sub>Cl molecules from these membranes significantly improved both CO<jats:sub>2</jats:sub> permeation and CO<jats:sub>2</jats:sub>/N<jats:sub>2</jats:sub> separation capabilities. Therefore, the present study provides insight that should be useful in the development of high‐performance CO<jats:sub>2</jats:sub> separation membranes via the effect of the thermally induced liberation of small molecules. © 2017 American Institute of Chemical Engineers <jats:italic>AIChE J</jats:italic>, 64: 1528–1539,
