Polymers of Intrinsic Microporosity in the Design of Electrochemical Multicomponent and Multiphase Interfaces

Abstract

Polymers of intrinsic microporosity (or PIMs) provide porous materials due to their highly contorted and rigid macromolecular structures, which prevent space-efficient packing. PIMs are readily dissolved in solvents and can be cast into robust microporous coatings and membranes. With a typical micropore size range of around 1 nm and a typical surface area of 700−1000 m2 g−1, PIMs offer channels for ion/molecular transport and pores for gaseous species, solids, and liquids to coexist. Electrode surfaces are readily modified with coatings or composite films to provide interfaces for solid|solid|liquid or solid|liquid|liquid or solid|liquid|gas multiphase electrode processes.

Size‐Selective Photoelectrochemical Reactions in Microporous Environments: Clark Probe Investigation of Pt@g‐C3N4 Embedded into Intrinsically Microporous Polymer (PIM‐1)

“…Polymers of intrinsic microporosity (or PIMs) [22] are formed with a highly contorted molecularly rigid backbone, and therefore provide uniquely processable materials that are soluble in organic solvents and readily cast into microporous films and deposits [23] . Importantly, the rigid polymer backbone has been proposed to not strongly interact with the surface of nanocatalyst guests to maintain an active unblocked catalyst surface [24] . At the same time photocatalysts would be expected to be less likely to degrade the PIM polymer host due to insufficient molecular interaction.…”

Formulation of silica‐based corn oil transformed polyester acryl amide‐phenol formaldehyde corrosion resistant coating material

“…Shortcomings of VO‐based polymeric material was overcome here by introducing acryl, ester, amide, and phenyl group in the final matrix. It was hypothesized that a multicomponent system will result in a well adhered hydrophobic corrosion protective coating 27,28 . All the components in the coating system have been chosen based on the output of successive steps.…”

Control Over the Morphology of Electrospun Microfibrous Mats of a Polymer of Intrinsic Microporosity

“…Its high rigidity results in enhanced gas separation performance with a superior vapour sorption capability [15]. Moreover, thanks to its basicity with the Tröger's base, PIM-EA-TB can act as an ion-conducting material and can be used to construct ionic diodes [30]. To the best of our knowledge, no research on the electrospinning of PIM-EA-TB has been published.…”
