Sorption and permeation properties of polycetylmethylsiloxane to methane and n-butane

Key Points

• Sorption capacity for methane is significantly higher than for n-butane, revealing distinct gas interactions.
• The permeability coefficients were determined, showing a marked difference in behavior for both gases.
• Experimental analysis of polycetylmethylsiloxane’s properties assessed various concentrations of methane and n-butane.
• Understanding these properties could enhance material selection for gas separation technologies.
