A hypercrosslinked porous
organic polymer was modified by post-oxidation and post-sulfonation to obtain a
porous platform with high density of acidic groups. Such acidified material
exhibits record high NH3 adsorption capacity per surface area, fast
adsorption rate, and recyclability at low desorption temperature. Noticeably,
the coating of the polymer with PDMS represents a facile and efficient route to
enable both significant improvement of low-pressure NH3 capacity
(~40-fold enhancement (0.04 to 1.41 mmol g-1) with respect to
non-modified polymer at 500 ppm) and hydrophobicity associated with the
selective sorption of NH3 over water vapor (hydrophilic for
non-coated material). This material is easy to prepare, cost-effective, and
scalable to mass production.
