Microporous polymer microspheres with amphoteric character for the solid-phase extraction of acidic and basic analytes [PDF]

open access: yes, 2020
Solid-phase extraction (SPE) is a widely-used and very well-established sample preparation technique for liquid samples. An area of on-going focus for innovation in this field concerns the development of new and improved SPE sorbents that can enhance the

Hierarchical macroporous PolyDCPD composites from surface-modified calcite-stabilized high internal phase emulsions [PDF]

open access: yes, 2023
High Internal Phase Emulsions (HIPEs) of dicyclopentadiene (DCPD) were prepared using mixtures of surface-modified calcite (mCalcite) and a non-ionic surfactant. Twelve different emulsion formulations were created using an experimental design methodology.

Selective environmental remediation of strontium and cesium using sulfonated hypercrosslinked polymers (SHCPs) [PDF]

open access: yes, 2019
Sulfonated hypercrosslinked polymers based on 4,4’-bis(chloromethyl)-1,1’-biphenyl (BCMBP) were synthesized via metal-free (SHCP-1) and conventional Lewis acid-catalyzed (SHCP-2) Friedel-Crafts alkylation routes.

Dispersible microporous di-block co-polymer Nanoparticles via polymerisation-induced self-assembly [PDF]

open access: yes, 2019
Microporous materials are predominantly formed as insoluble powders which means that they can be difficult to process. Here we report a new class of solvent-dispersible porous polymers synthesised by reversible addition-fragmentation chain transfer ...

Sulfonated hypercrosslinked polymer enhanced structural composite supercapacitors

open access: yesComposites Science and Technology, 2023
Structural supercapacitors are multifunctional devices able to bear mechanical load while storing electrical energy. Carbon fibres can be used as a bifunctional component within structural supercapacitors, acting both as current collector and mechanical reinforcement.

Structural and Compositional Characterization of Fungus‐Derived Pyrolytic Carbon Architectures

open access: yesAdvances in Materials Science and Engineering, Volume 2016, Issue 1, 2016., 2016
Three distinctive pyrolytic carbon structures, derived from three specific tissues of Agaricus bisporus mushroom, were studied and characterized. The three structures discovered within the stalk, cap, and cap skin tissues were found to contain unique microarchitectures, which were preserved upon anoxic carbonization.

Hypercrosslinked Phenolic Polymers with Well‐Developed Mesoporous Frameworks

open access: yesAngewandte Chemie, 2015
AbstractA soft chemistry synthetic strategy based on a Friedel–Crafts alkylation reaction is developed for the textural engineering of phenolic resin (PR) with a robust mesoporous framework to avoid serious framework shrinkage and maximize retention of organic functional moieties. By taking advantage of the structural benefits of molecular bridges, the

Nanoporous hypercrosslinked polymers containing Tg enhancing comonomers [PDF]

open access: yesPolymer, 2015
Abstract Hypercrosslinked polymers containing functionalized alternating copolymer sequences of substituted stilbene or styrene and N-aryl substituted maleimides have been synthesized. Alternating copolymers containing these comonomers possess semi-rigid structures, and incorporation of these units into the precursor polymer particles for ...
