“…Polyvinylamine (PVAm) is one type of the most promising polymer material for gas separation, especially in the field of acidic gas separation, which possesses higher permeance and separation selectivity [28][29][30][31][32][33][34]. Recently, PVAm is also used as polymer matrix in the mixed matrix composite membrane.…”

“…[ 9 ] Aliphatic amines are among the most popular choice of organic bases as adsorbents for CO 2 adsorption via neutralization to form carbamates (see Figure 1 ). These can be free amine molecules, [ 10 ] supported polyamine polymers, [ 11 ] and grafted amine groups on a support material. [ 12 ] Regardless of the form of amine, the principle of neutralization is essentially the same.…”

“…In recent years, our group introduced a novel method that various amino group-containing small molecules were used to modify amino group-rich polymers via hydrogen-bonding crosslinking, which not only could achieve the optimization of membrane material structures at multiple levels, but also could increase the carrier concentration in the membranes [283][284][285][286][287]. Following this strategy, ethylenediamine (EDA), piperazine (PIP), monoethanolamine (MEA) and methylcarbamate (MC) were used as modifiers to incorporate into the PVAm matrix, and the formed hydrogen-bonding crosslinked networks were illustrated in Fig.…”
