Poly(acrylic acid) (PAA) is a polymer of acrylic acid, which has a carboxylic group on each monomer unit. This polymer becomes a polyelectrolyte in water via dissociation of the acid groups.
investigated With considering the effect of dispersion stability of slurry on Zeta potential and dissociation of dispersant the optimum pH range for the stable slurry is between 8 to 11The relationship of different solid content slurry and the amount of best dispersant ...
Less stability and more aggregation were observed with the lower molecular weight PAA. Additionally, PAA dissociation caused by pH changes affected the clustering of the nZVI particles. At higher MW, the hydrodynamic diameter and size distribution become smaller and tighter, respectively, allowing a ...
The aptamer bases [32] with a lower dissociation constant (20.8 ± 3.1 nM) and outstanding discernment was chosen for T-2 recognition. The present study will provide a worthwhile understanding of the FRET mechanism between AuNCs and AuNPs in the presence of PDDA. Meanwhile, the semi-...
However, adding PAANa modifies the dissociation of PAAH written in equation (1) and shifts the equilibrium to the left hand side term (buffer medium). As stated above, this will impact the shape of the nanoparticles, the nature of the planes constituting the nanoparticles, as well as their ...

Well-dispersed PZT slurries with negligibly small Pb~(2+) dissolution were obtained in the alkaline side due to the electrostatic steric hindrance effect of adsorbed polyelectrolyte dispersant molecules with a high dissociation ratio of carboxylic acid groups. The homogeneous dense microstructure and ...
NF networks effectively enhances the thermal stability of PAA–L drogels, possibly through enhancing the hydrogen bonding interactions among P and LCNF, and thus limiting the mobility and dissociation of PAA–LCNF networ ever,...
There is general agreement that the growth evolution of CNTs within PAA templates follows five different stages [28] characterized by (i) pyrolysis of the carbon feedstock, (ii) carbon dissociation along the deposition zone, (iii) carbon transfer from the source to the PAA template, (iv) carbo...
