  • Does CPAM reduce water adsorption density on Na-MMT surface?
  • The adsorption of CPAM reduces highly the amount of water adsorption density on Na-MMT surface than PAM and APAM. CPAM adhesion is high and more accelerated by the positive charge of its molecules with the negative charge of Na-MMT. Polymer molecules adsorption reduces the vertical distance between polymer and the surface of MMT particles.
  • What is the molecular weight of Pam?
  • The molecular weight (MW) of commercial PAM ranges from 10 5 to >10 7 Da. High MW PAM (>10 6 Da) has a wider range of applications due to its high viscosity, drag reduction capabilities, and water retention characteristics. 6, 7, 8 PAM is widely used in environmental systems including: 1. 2. 3.
  • What are the adsorption characteristics of Apam and CPAM molecules?
  • Including the adsorption characteristics of PAM, APAM and CPAM. The simulation results show that PAM and APAM molecules have low adsorption density on Na-MMT surface compared to CPAM molecules. PAM and APAM molecules interact more through h-bonding with their own molecules leading to a weak interaction with Na-MMT particles.
  • What is the adsorption mass of CPAM and NPAM?
  • The adsorption masses of the CPAM 30% on the alumina surface and alumina surface with montmorillonite adsorption layer are 1.29 mg/cm 2 and 3.56 mg/cm 2, respectively. The existence of montmorillonite can greatly enhance the adsorption of the CPAM and NPAM on the sensor. Figure 5.
