Switchable Porosity: Can Microporous Materials Be Controlled?

Click For Summary

Discussion Overview

The discussion centers around the possibility of controlling the porosity of microporous materials through external stimuli, such as optical, pressure, or electrical means. Participants are exploring the concept of "Artificial Stomata," where the opening and closing of pores can be externally manipulated.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about the feasibility of switching the porosity of microporous materials using external stimuli.
  • Another participant suggests looking into metal-organic frameworks (MOFs), noting their adjustable characteristics, including pore size and surface area, due to their structural engineering.
  • A participant expresses difficulty in finding relevant literature on the topic and requests specific recommendations.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus, as there are varying levels of knowledge and experience regarding the literature on the subject, and the feasibility of the proposed concept remains uncertain.

Contextual Notes

Some limitations include the potential dependence on specific definitions of porosity and the types of external stimuli discussed, as well as the unresolved nature of the search for relevant literature.

Is it possible to switch the porosity of any microporous material by external stimuli (eg. optical, pressure or electrical ). I'm trying to imagine something akin to an "Artificial Stomata" where the pore opening & closing Can be externally controlled.

I'd be very thankful if someone could point me to the relevant literature.

You must check metal organic frameworks. They are highly famous with their adjustable characteristics(pore size, surface area etc) since they are structurally engineered materials. There may some types, that changes their pore size with an external stimuli.
 
yes I did. But preliminary search doesn't seem to reveal much. Anything particular shall be very appreciated :)
