The change of zeta potential of pulp slurry during the polyelectrolytes multilayer built up and the factors affecting the adsorption efficiency of polyelectrolytes on pulp were studied.

The research results showed that the deposition technique can add the absorbed amount of polyelectrolyte and cause potential changes in fiber surface.

The polyelectrolyte membrane was prepared by interaction between chitosan (CS) and carboxymethylcellulose (CMC) using glutaraldehyde as linkage reagent.

Polyelectrolyte complex formed from diazoresin(DR) as cationic polyelectrolyte and alkaline hydrolysate of styrenemaleic anhydride copolymer(PSMNa) as anionic polyelectrolyte does not dissolve in water or organic solvents due to its ionic crosslinking structure.

Recently, in drug controlled release system, polyelectrolyte complexes have been rewarded much attention.

his review introduced the forming mechanism and character of polyelectrolyte(PEL) and polyelectrolyte complex(PELC),gave a retrospect to their contribution in the leather theory study, and pointed out their important denotation in theory studying and practice.
