Interaction of Ethanol Vapour with Silane-Modified Surface of Corning Porous Glass CPG-10

Figure 7

A cross-plot of ethanol adsorption isotherms (millimoles per gram unmodified versus millimoles per gram DMDCS-modified) for unmodified CPG-10 against DMDCS-modified CPG-10 to reveal changes occurring. It shows the gradual multilayer adsorption increase (small slope) followed by a jump during capillary condensation (bigger slope), on the modified sample.
