  • What is cationic polyacrylamide (CPAM)?
  • Cationic polyacrylamides (CPAMs) are widely utilized due to their excellent performance in flocculation and sludge dewatering [ 2 ]. Numerous studies have been conducted on CPAM synthesis technologies, including grafting, free radical polymerization, and polymer modification [ 3 ].
  • Is acrylamide cationic or nonionic?
  • Polyacrylamides can either be nonionic, anionic, or cationic. The nonionic polymer is made solely from acrylamide monomer, while the anionic form also uses an acrylic acid monomer, and the cationic form also uses a cationic acrylamide based salt monomer (e.g. ethanaminium, N,N,N-trimethy1-2-[(1-oxo-2-propenyl)oxy]-, chloride).
  • Can cationic polyacrylamide flocculants be used to treat oily water?
  • Shu, G., Bu, K., Zhao, B. & Zheng, S. Evaluation of newly developed reverse demulsifiers and cationic polyacrylamide flocculants for efficient treatment of oily produced water. Colloids Surf. A 610, 125646 (2021). This work was supported by grants from the “Qihang Program” of the Southwest Petroleum University (2025QHZ001) awarded to C.Z.
  • What is a composite gel based on -cyclodextrin-functionalized polyacrylamide (hmpam)?
  • A composite gel named NAF was created by combining self-synthesized β-cyclodextrin-functionalized hydrophobically modified polyacrylamide (HMPAM) with a viscoelastic surfactant (VES) (Fig. 6a) 19.
