  • What is polyacrylic acid & polyacrylamide?
  • Polyacrylic acid (PAA) and polyacrylamide (PAM) are highly water-absorbent polymers with three-dimensional network structure and widely applied in the industrial water treatment ( Fan et al., 2013; Ahmed, 2015 ), such as organic contaminations ( Xing et al., 2017) and heavy metal wastewater ( Ma et al., 2017; Zhang et al., 2018; Zhou et al., 2018).
  • How does polyacrylamide (Paa) bind to GCN?
  • To further immobilizing GCN and strengthening hydrogel, polyacrylamide (PAM) was introduced to form interpenetrating network with PAA. In this structure, PAM acted the role of cheese in a pizza, tightly covering and immobilizing GCN into the interpenetrating network.
  • Can photocatalysts and polymers solve separation problems in composite hydrogels?
  • The composite hydrogels composed of photocatalysts and polymers with bulk structure may supply a strategy to solve these separation issues. Photocatalysts are distributed into monomers and fixed during the polymerization of monomers (Sun et al., 2017; Yang et al., 2017; Hou et al., 2019 ).
  • What is the role of GCN in polymerization of acrylic amide?
  • GCN acted as the photoinitiator in the polymerization of acrylic amide. During wastewater treatment (GCN) was immobilized in network of polyacrylic acid (PAA) hydrogel to solve this issue. To further immobilizing GCN and strengthening hydrogel, polyacrylamide (PAM) was introduced to form interpenetrating network with PAA.
