Enhanced methane sorption in densified forms of a porous polymer network
Kizzie, A., Dailly, A., Perry, L., Lail, M., Lu, W., Nelson, T., ... Zhou, H-C. (2014). Enhanced methane sorption in densified forms of a porous polymer network. Materials Sciences and Applications, 5(6), 387-394. DOI: 10.4236/msa.2014.56044
Multi-gram synthesis and densification is presented for a porous polymer network (PPN-4) examined as a possible vehicular methane storage material. Compaction at 17,000 psi doubled the bulk density of the material and unexpectedly increased microporosity within the material. As a result, the densified material exhibits higher excess gravimetric methane uptake and improved total volumetric methane uptake relative to the powder.
