Name of polyelectrolyte
Applications others
1 Polyacrylic acid in disposable diapers, ion exchange resins and adhesives + thickening, dispersing, suspending and emulsifyingagents in pharmaceuticals, cosmetics and paints
DiapersHand sanitizerMascaraAftershaveToothpasteHair-styling products (gels, dyes, sprays)MoisturizerPet shampooMetal polish
2 Poly(methacrylic acid)
3 Polyethylenimine Used as a polyelectrolyte multilayer on charged surfaces to provide a biocompatible coating on surfaces
Detergents, adhesives, water treatment, printing inks, dyes, cosmetics, and paper industry, adhesion promoter, lamination primer, fixative agent, flocculant, cationic dispersant, stability enhancer, surface activator, chelating agent, scavenger for aldehydes and oxides
4 Poly(N-isopropylacrylamide)
5 Polyvinylpyrrolidone as an adhesive in glue stick and hot-melt adhesives
as an emulsifier and disintegrant for solution polymerization
as a liquid-phase dispersion enhancing agent has excellent wetting properties and readily
forms films. This makes it good as a coating or an additive to coatings
as a special additive for batteries, ceramics, fiberglass, inks, and inkjet paper, and in the chemical-mechanical planarizationprocess
6 Polyacrylonitrile used to produce large variety of products including ultra filtration membranes, hollow fibers forreverse osmosis, fibers for textiles, oxidized PAN fibers. PAN fibers are the chemical precursor of high-quality carbon fiber
absorbs many metal ions and aids the application of absorption materials
---properties involving low density, thermal stability, high strength and modulus of elasticity---- high tensile strength and tensile modulus are established by fiber sizing, coatings, production processes, and PAN's fiber chemistry
7 PolyDADMAC Effluent treatment Pulp and paper industry[edit]
Used as flocculants in water and wastewater treatment. In the mining and the process of mineral, it is always used in
Water purification ability to modify surfaces and provide
cationic character allows the user to selectively attract negatively charged functional groups to the coated surface
dewater flocculants which can extensively applied in treating various mineral mud, such as coal, taconite, natural alkali, gravel mud and titania.
8 Polyaniline -attractive for acid/base chemical vapor sensors, supercapacitors and biosensors.- applications such as actuators, supercapacitors and electrochromics
--their light weight, conductivity, mechanical flexibility and low cost.-- printed circuit board manufacturing (final finishes, used in millions of m² every year), antistatic and ESD coatings, and corrosion protection
9 Poly(vinyl alcohol) used as an emulsion polymerization aid, as protective colloid, to make polyvinyl acetate dispersions.
Used in eye drops (such as artificial tears to treat dry eyes) and hard contact lens solution as a lubricant
PVA fiber, as reinforcement in concrete As an embolization agent in medical
procedures
Thickener, modifier, in polyvinyl acetate glues
Textile sizing agent Paper coatings, release liner, As a water-soluble film useful for
packaging. An example is the envelope containing laundry detergent in "liqui-tabs".
