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.

Does anionic polyacrylamide affect the electrostatic potential of cotton fibers?

The adsorption isotherm model fitting and analysis of electrostatic potentials revealed that the affinity between dyes and fibers weakened after treatment with anionic polyacrylamide, leading to a decrease in the electrostatic potentials of cotton fibers.

Can anionic polyacrylamide reduce dye adsorption rate?

Nevertheless, the rapid adsorption rate of dyes can impact the evenness of dyeing. This study explores the use of anionic polyacrylamide (APAM) in the modification bath to reduce dye adsorption rate and enhance dye desorption during cellulose fibers dyeing.

How are polyacrylamide/polyanionic cellulose/Zr-Cp composite hydrogels prepared?

In this paper, a series of polyacrylamide/polyanionic cellulose/Zr–CP (PAM/PAC/Zr–CP) composite hydrogels were prepared via acrylamide polymerization in aqueous solutions of PAC and disodium terephthalate (Na2BDC), followed by posttreatment in 0.1 M ZrOCl2 solution.

What is polyacrylamide (PAM)?

Polyacrylamide (PAM) is a water-soluble synthetic polymer which possesses useful properties such as good adhesiveness, proper hygroscopicity, high hydrophilicity, and non-toxicity. PAM composites with CNCs can be obtained by mixing an aqueous solution of PAM and an aqueous suspension of CNCs. PAM is a carbochain polymer with a side amide group.

Does anionic polyacrylamide improve dyeing kinetics?

Dyeing kinetics results demonstrated that the modification with anionic polyacrylamide reduced the adsorption rate of reactive dye and improved the level dyeing property. However, there were no significant changes in final dye uptake, dye fixation, washing and rubbing fastness.
