Porous polymer networks and ion-exchange media and metal-polymer composites made therefrom

摘要

Porous polymeric networks and composite materials comprising metal nanoparticles distributed in the polymeric networks are provided. Also provided are methods for using the polymeric networks and the composite materials in liquid- and vapor-phase waste remediation applications. The porous polymeric networks, are highly porous, three-dimensional structures characterized by high surface areas. The polymeric networks comprise polymers polymerized from aldehydes and phenolic molecules.

1. A method for remediation using a porous, three-dimensional, aromatic polymeric network comprising: an organic polymer comprising phenolic groups, wherein the phenolic groups are crosslinked through linkages comprising one or more non-phenolic aromatic rings; and metal nanoparticles distributed within the polymeric network, the method comprising: exposing the polymeric network to a sample comprising iodine or Hg, whereby the iodine or Hg is adsorbed in the pores of the polymeric network; and subsequently removing the polymeric network and the adsorbed iodine or Hg from the sample.
