Synthesis of highly ordered mesoporous polymer networks

Abstract

Synthesis of highly ordered three-dimensionally interconnected mesoporous hydrocarbon polymer networks exhibiting Bragg X-ray diffraction is reported by replicating the mesoporous MCM-48 and SBA-15 channel frameworks.

Templated Synthesis of Mesoporous Superparamagnetic Polymers

“…This was carried out by in situ polymerization as reported by Kim et al [21]. Briefly, a precursor solution of divinylbenzene (DVB) (Aldrich) with a free radical initiator, 1,1′-azobis(cyclohexane-carbonitrile) (ACC) (Aldrich) (DVB/ACC mol ratio: 12) was added dropwise until the structural porosity of the composite was filled up to the desired level.…”

“…In a pioneering work, Johnston et al [2] reported on the preparation of ordered mesoporous polymers by using colloidal silica crystals as templates. Kim et al [3] synthesized highly ordered three-dimensionally interconnected mesoporous polymers by using mesostructured MCM-48 and SBA-15 silica materials as templates. Lee et al [4] employed a mesocellular silica foam as template to fabricate a porous polymer containing a bimodal porosity made up of two pore systems of sizes centred at 3 nm and 17 nm.…”

Direct triblock-copolymer-templating synthesis of ordered nitrogen-containing mesoporous polymers

“…Until now, a large number of ordered mesoporous materials with various compositions and structures have been successfully synthesized, including two-dimensional (2-D) hexagonal or/and 3-D cubic mesostructured silicates [7][8][9], metal oxides [10], metal sulfides [11], metals [12], polymers, and carbons [13][14][15][16]. In addition, further modification of these mesostructures can endow the materials with additional physicochemical functions, and therefore improve their performance in practical applications.…”

Template‐Free Tuning of Nanopores in Carbonaceous Polymers through Ionothermal Synthesis

“…[5][6][7][8][9][10][11][12] It is, however, much more difficult to design mesoporous organic materials (i.e., with pores in the range of 2-50 nm). Generally, mesoporous materials such as silica are synthesized through a soft templating approach, [13][14][15][16][17] whereas carbons or polymer networks usually require the use of silica-based hard templates, [1,[18][19][20] but some reports with a soft templating approach were recently reported as well. [21][22][23] Although this methodology led to interesting materials, it is practically a ''no-go'' for industrial applications because of its complexity and high cost.…”
