  • Does Pam conformation influence the behaviour of polyacrylamide/cellulose nanocrystal (Pam/CNC) composites?
  • In this work, a series of polyacrylamide/cellulose nanocrystal (PAM/CNC) composites with a wide range of compositions were prepared by a solution casting method. Subsequently, the influence of the PAM conformation on the behaviour of the PAM/CNC composites was studied.
  • Why is nonionic polyacrylamide used as anti-scouring admixture?
  • Nonionic polyacrylamide was selected as anti-scouring admixture to eliminate the influence of different polymer electrical properties (Lu et al. 2025 ). The molecular weight of PAM is more than 10 million Daltons, and its main chain is connected with a C=O bond and an amino functional group as a branch chain structure, as shown in Fig. 2.
  • How are cellulose network-assisted hydrogels formed?
  • Firstly, different proportions of WSCA (DS = 0.63) were dissolved in water, then the acrylamide (Am) monomer and ammonium persulfate (APS) were added into the aqueous solution followed by the consequent in situ free radical polymerization, resulting in the formation of the cellulose network-assisted composite hydrogels.
  • How is polyacrylamide a hydrolyzed polymer?
  • The process generally involves the addition of a strong base to a homopolymer of polyacrylamide. This can be done in an aqueous solution, inverse emulsion. Recently, a process to produce dry forms of hydrolyzed polyacrylamide has been developed. This allows for the preparation of very high-molecular-weight anionic polymers.
