  • Is polyacrylamide a cationic or nonionic polymer?
  • Recently, polyacrylamide was introduced in geotechnical engineering into the process of clay treatment . Regarding the type of polymer charge, polyacrylamide can be divided into three types: nonionic (PAM), anionic (APAM), and cationic (CPAM).
  • Can polyacrylamide/clay nanocomposite be used as a drilling fluid additive?
  • R. Jain and Mahto proved that by defining an appropriate grade of polyacrylamide/clay nanocomposite (PANC) as a drilling fluid additive, it will function as an effective inhibitor and shale stabilizer.
  • Why does Apam have a high energy?
  • APAM exhibits a high energy, as the distance between its particles and MMT increase, due to high electrostatic repulsion caused by the negative charge which weak its adsorption. Electrostatic and Van der Waals forces decreases highly in CPAM system than others (PAM and APAM system);
  • Can UV-initiated template polymerization prepare a novel anionic polyacrylamide with a microblock structure?
  • Received 7th May 2017 , Accepted 26th May 2017 Ultraviolet (UV)-initiated template polymerization (UTP) was used as a feasible strategy to prepare a novel anionic polyacrylamide (APAM) with a microblock structure.
