Abstract A highly rigid amine‐based polymer of intrinsic microporosity (PIM), prepared by a polymerization reaction involving the formation Tröger’s base, is demonstrated to act as an ionic diode with electrolyte‐dependent bistable switchable states.
A polymer with intrinsic microporosity, when immobilized into 20 μm pores, is shown to result in ionic rectification effects due geometric asymmetry potential for future applications desalination.
Abstract The enzymeless glucose oxidation process readily occurs on nano‐gold electrocatalyst at pH 7, but it is highly susceptible to poisoning (competitive binding), for example from protein or chloride. Is shown here that gold nanoparticle catalyst can be protected against by a polymer of intrinsic microporosity (PIM‐EA‐TB with BET surface area 1027 m 2 g −1 ). This PIM material when protonated, achieves triple protection effect (i) size selective repulsion larger molecules (albumins) and...
Vacuum carbonization of organic precursors usually causes considerable structural damage and collapse morphological features. However, for a polymer with intrinsic microporosity (PIM-EA-TB Brunauer-Emmet-Teller (BET) surface area 1027 m(2)g(-1)), it is shown here that the rigidity molecular backbone retained even during 500 °C vacuum carbonization, yielding novel type microporous heterocarbon (either as powder or thin film membrane) properties between those conducting carbon. After scanning...
There remains a major materials challenge in maintaining the performance of platinum (Pt) anode catalysts fuel cells due to corrosion and blocking active sites.
Abstract A highly rigid amine‐based polymer of intrinsic microporosity (PIM), prepared by a polymerization reaction involving the formation Tröger’s base, is demonstrated to act as an ionic diode with electrolyte‐dependent bistable switchable states.
Abstract A film of the polymer intrinsic microporosity PIM‐7 is coated onto a glassy carbon electrode and resulting effects on electron transfer reactions are studied for three different types processes: (i) aqueous solution based, (ii) solid state surface immobilised, (iii) electrocatalytic processes electrodeposited palladium. The reactivity hydroquinone oxidation in phosphate buffer shown to be linked causing slightly lower rate mass transport without detrimental reaction kinetics. Next,...
Nanohybrid materials based on nanoparticles of the intrinsically microporous polymer PIM-1 and graphene oxide (GO) are prepared from aqueous dispersions with a reprecipitation method, resulting in surface GO sheets being decorated PIM-1. The significant blueshift fluorescence signals for GO/PIM-1 nanohybrids indicates modification optoelectronic properties presence due to their strong interactions. stiffening Raman G peak (by nearly 6 cm–1) further p-doping PIM.

Hybrid nanomaterials fabricated by the heterogeneous integration of 1D (carbon nanotubes) and 2D (graphene oxide) showed synergy in electrical mechanical properties. Here, we reported infiltration carboxylic functionalized single-walled carbon nanotubes (C-SWNT) into free-standing graphene oxide (GO) paper for better properties than native GO. The stacking arrangement GO sheets its alteration presence C-SWNT were comprehensively explored through scanning electron microscopy, X-ray...
