The initially very promising transport properties of glassy high free volume polymers deteriorate rapidly over time. In this work, we focused on this aging phenomenon in two polymers of intrinsic microporosity (PIMs), namely PIM-1 and PIM-EA-TB. To identify the main mechanisms involved, we studied the time-declines of permeability and diffusivity of methanol vapours in flat membranes with approximately equal thicknesses. The permeation measurements were carried out using a continuous flow permeation method with carrier gas, where the methanol vapours were held at constant activity 0.2 at 25°C. Two different experimental modes were used: (i) continuous experiments that consisted of one long experiment with a duration of over 650 hours for each polymer and (ii) momentary experiments that consisted of a vast number of short (ca. 6 hours) consecutive measurements of transient permeation. The observed decreases of methanol permeability due to aging were more intense in the case of continuous mode for both polymers. In other words, the aging was ca.

“…In addition, when preparing thicker samples (dense films), different evaporation conditions are established within the membrane section that lead to a less tightly packed polymer in the bulk. A sample prepared on the (PAN + PDMS layer) support showed a reduction in permeance and an increased selectivity over time, as usually due to physical ageing [59,60]. However, the membranes prepared on the (F-42 + silicone layer) support become less selective upon ageing.…”

Polymers of intrinsic microporosity (PIMs) have been identified as potential next generation membrane materials for the separation of gas mixtures of industrial and environmental relevance. Based on the exceptionally rigid methanopentacene (MP) structural unit, a Polymer of Intrinsic Microporosity (PIM-MP-TB) was designed to demonstrate high selectivity for gas separations. PIM-MP-TB was prepared using PIMs, PIM-MP-TB is prepared in four simple steps from a cheap starting material.
