A new strategy to synthesis of porous polymers from plastic waste for highly efficient adsorption of rhodamine B, malachite green and I2 vapor

Halogen-Bonding Interaction-Mediated Efficient Iodine Capture of Highly Nitrogen-Functionalized Hyper-Crosslinked Polymers

“…Despite having a very low BET surface area and nonporous characteristics, our nitrogen-functionalized HCPs in this study exhibited very good performances toward iodine adsorption compared to other benchmark porous adsorbents such as metal−organic frameworks (MOFs), 58 nanocomposites, 59 covalent-organic frameworks (COFs), 60,61 porous organic polymers (POPs), 27,62,63 hyper-crosslinked polymers (HCPs), 16,18,64−66 covalent triazine frameworks (CTFs), 67 and conjugated mesoporous polymers (CMPs). 68 These results strongly suggested that in addition to designing materials with high porosities, highly functionalized nonporous materials can also be used to accomplish effective adsorption of chemical species, in this case molecular iodine.…”

Statistical Optimization of Operational Parameters on Congo Red Adsorption Using Upscaled Polystyrene

“…EPS waste and cyanuric chloride were used to synthesize porous polymers that effectively adsorbed Rhodamine B and Malachite green. The high adsorption efficiency of these porous polymers was due to functional groups like nitrile groups, phenyl groups, and hydroxyl groups [26].…”

Upcycling waste expanded polystyrene into UV-excited dual-mode multicolor luminescent electrospun fiber membranes for advanced anti-counterfeiting

“…12 Converting waste EPS to recycled products is considered one of the best disposal methods in terms of sustainability and environmental concerns. 13,14 Some functional materials based on waste EPS such as absorption and separation materials for water treatment [15][16][17][18] or gas separation, 19,20 and energy storage and conversion materials for supercapacitor and battery applications, [21][22][23][24] etc. have been reported in the literature.…”
