Cross-Linked Poly(orthocarbonate)s as Organic Solvent Sorbents

Abstract

A simple method for the synthesis of a series of cross-linked poly(orthocarbonate)s (CPOC), based on tetraethyl orthocarbonate, is reported. Structural evidence for CPOCs was obtained from 13 C solid-state NMR, FT-IR, and thermal analysis. All polymers have high and fast uptake of organic fluids such as tetrahydrofuran, dichloromethane, dichloroethane, and the dry-cleaning fluid blend "trichlor".

Superhydrophobic Mesoporous Graphene for Separation and Absorption

“…[1,2] To address these water pollution issues, absorption technologies are considered one of the most useful approaches. To date, a number of absorbents including clay, [3] active carbon, [4,5] polymers, [6][7][8] and carbon nanotubes [9] have been developed for removal of oil spills or organic contaminants from water. However, these absorbent materials have their respective drawbacks such as poor selectivity and limited working capacity, which limit their practical use on a large scale.…”
