WebMolecular dynamics techniques have been used to investigate the pronounced permeability and selectivity of polymers of intrinsic microporosity (PIM). While helium exhibited greater permeability coefficients due to higher diffusivity resulting from its small molecular size, the higher permeability coefficients of carbon dioxide WebUniversity of Notre Dame. mei 2024 - jul. 20243 maanden. Notre Dame, Indiana. Streamlined the process of making breakthrough membranes with polymers of intrinsic. microporosity by using literature to incorporate less time-intensive synthetic steps. Proved the potential for a new family of polymers to exceed industry benchmarks in mixed-gas.

WebThis work reports on the preparation and gas transport performance of mixed matrix membranes (MMMs) based on the polymer of intrinsic microporosity (PIM-1) and potassium dodecahydrododecaborate (K₂BH) as inorganic particles (IPs). The effect of IP WebI am involved in organic synthesis, monomer & polymer design, the preparation and characterisation of novel Polymers of Intrinsic Microporosity (PIMs) both within the … north american power symposium

Microporous polymer adsorptive membranes with high processing …

Polymers of intrinsic microporosity (PIMs) are a unique class of microporous material developed by research efforts led by Neil McKeown, Peter Budd, et al. PIMs contain a continuous network of interconnected intermolecular voids less than 2 nm in width. Classified as a porous organic polymer, PIMs generate … See more PIMs require that the non-network macromolecular structure is rigid and non-linear. In order to maintain permanent microporosity the rotation along the polymer chain must be prohibited through the use of fused ring … See more Due to the presence of intrinsic microporosity these polymers have high-free volume, high internal surface area, and have a high … See more WebPorphyrin-based polymers of intrinsic microporosity (PIMs) in photocatalytic degradation of a mustard-gas simulant (2-chloroethyl ethyl sulfide (2-CEES)) was demonstrated. Under blue-ultraviolet (UV) light-emitting diode (LED) irradiation, porphyrin-based PIMs PP-H2 and PP-Zn(II) worked as effective heterogeneous photocatalysts for oxidation of 2-CEES. WebMiscible blends of Matrimid and carboxylated polymers of intrinsic microporosity (cPIM-1) at the molecular level have been discovered. Their miscibility has been confirmed by … north american power scam
