Application of Nano-Materials as Synergistic Retention Aid in Paper Making
Various negatively charged and positively charged inorganic nano-materials have been suggested to constitute the so-called microparticle retention systems with cationic or anionic polymers. Anionic microparticle retention systems consisted of cationic polymers and negatively charged inorganic nano-materials with various aspect ratios were reviewed while their working mechanism were analyzed. Cationic microparticle retention systems made up of either naturally or organo-modified cationic nano-materials were introduced.
