Highly Stable Porous Polymer Networks with Exceptionally High Gas-Uptake Capacities



original image

Highly stable porous polymer networks (PPNs) are synthesized through Yamamoto homocoupling reaction between tetrahedral monomers. Among those polymers, PPN-4 shows exceptionally high Langmuir surface area of 10063 m2 g−1 (SABET: 6461 m2 g−1). It also exhibits ultra-high hydrogen (158 mg g−1), methane (389 mg g−1), and carbon dioxide (2121 mg g−1) storage capacities. These properties make it a perfect adsorbent for clean energy applications.
