Hyper-Crosslinked Polymer Nanocomposites Containing Mesoporous Silica Nanoparticles with Enhanced Adsorption Towards Polar Dyes

Abstract

The development of new styrene-based hyper-crosslinked nanocomposites (HCLN) containing mesoporous silica nanoparticles (MSN) is reported here as a new strategy to obtain functional high surface area materials with an enhanced hydrophilic character. The HCLN composition, morphology and porous structure were analyzed using a multi-technique approach. The HCLN displayed a high surface area (above 1600 m2/g) and higher microporosity than the corresponding hyper-crosslinked neat resin. The enhanced adsorption properties of the HCLN towards polar organic dyes was demonstrated through the adsorption of a reactive dye, Remazol Brilliant Blue R (RB). In particular, the HCLN containing 5phr MSN showed the highest adsorption capacity of RB.

Eco-Friendly Production of Hyper-Cross-Linked Polymers Using Mechanosynthesis and Bioresources: A Critical Review

“…Using two different precursors, namely tetraphenylethylene and 4-(5,6-diphenyl-1H-benzimidazol-2-yl)-triphenylamine, cross-linked with 1,4-bis­(chloromethyl)­benzene, rhodamine B-adsorbed amounts of up to 107 and 256 mg/g were obtained by HCPs based on the former and latter precursor, respectively . Guerritore et al evaluated another way to increase the adsorption capacity by including silica nanoparticles in a styrene-based HCP backbone, which resulted in Remazol Brilliant Blue R adsorption uptakes above 200 mg/g. More comprehensive information on this topic has been reported elsewhere. , …”

Mesoporous silica nanoparticles as carriers of active agents for smart anticorrosive organic coatings: a critical review

“…MSN are a class of materials widely investigated for several applications, ranging from energy storage, 7,8 water and air purification, [9][10][11][12][13][14] catalysis 15,16 optoelectronics, 17 drug delivery 18,19 or smart release of active agents. [20][21][22] For coating applications, MSN have several advantages, such as a chemically stable structure, low reactivity and compatibility with numerous matrices.…”

Fabrication of Hydroxyl‐Carboxyl Bifunctional Hyper‐Crosslinked Polymers for Selective Adsorption of Methylene Blue

“…Guerritore et al. 35 synthesized micro/mesoporous hyper‐crosslinked nanocomposites containing mesoporous silica nanoparticles, with an adsorption capacity of about 200 mg g −1 for Remazol Blue. MB is a cationic dye; so, the hydroxyl and/or carboxyl groups rather than thiol, amide, or amine were selected to enhance the static effect.…”
