Degradable and processable polymer monoliths with open-pore porosity for selective CO₂ and iodine adsorption

Abstract

Task-specific design of biodegradable and processable porous polymers is one of the primary requisite for their efficient day-to-day use to minimize polymer waste. Herein, a surfactant (or additive) free method...

Porous polyaminoamides via an exotemplate synthesis approach for ultrahigh multimedia iodine adsorption

“…25,26 In this context, it was observed that functional amines when embedded within a polarizable network such as polyaromatic amines and polyaminoamides show excellent iodine adsorption ability. [27][28][29][30] However, most of the reported materials demonstrate iodine adsorption ability only in the vapor phase and organic solvents. [31][32][33][34][35][36][37] Materials which show signicant iodine adsorption ability in water, are much less reported.…”

A comprehensive review on the synthesis techniques of porous materials for gas separation and catalysis

“…In other work, porous polyelectrolyte polymers were synthesized for iodine and CO 2 adsorption using colloidal templating involving the sol–gel strategy. [ 73 ] Tris(2‐aminoethylamine) monomer was reacted with N,N ′‐methylene (bis)acrylamide to form colloidal NPs, which on long‐duration (48 h) stirring form a cross‐linked gel. The freeze‐dried polymer can be further used in powder as an adsorbent material.…”

Microgels as Smart Polymer Colloids for Sensing and Environmental Remediation

“…In the past few decades, polyamine-based microgels have attracted significant attention due to their application toward the removal of anionic dyes and heavy metal ions. − The polyamine microgel has a positive charged surface because of protonated amine functionality, which results in electrostatic interaction with negatively charged pollutants, facilitating their elimination. , To explain the adsorption of heavy metal ions and anionic dyes, a plausible mechanism has been proposed where efficient adsorption of toxic metal ions is caused due to the chelation of metal ions with the amine-based chelating groups in addition to various supramolecular interactions (electrostatic interaction, H-bonding interaction, and π–π interaction). − …”
