Facile one-pot synthesis of nanoporous hypercrosslinked hydroxybenzene formaldehyde resins with high surface area and adjustable pore texture

摘要

Hydroxybenzene formaldehyde resins with high surface area (up to 1000 m~2 g~(-1)), high pore volume (up to 2.4 cm~3 g~(-1)) and adjustable pore size distribution have been synthesized by a facile one-pot method. The pore formation was confirmed to be a hypercrosslinked mechanism. These results extend the synthetic methods of hypercrosslinked polymers from conventional nonaqueous Friedel-Crafts condensation to aqueous phenol-aldehyde reaction.
