Insulating polymers are dielectric materials. When a nonpolar polymer is placed in an electric field, there may be an ionic or transient electric current. If there is a barrier to prevent these charges from leaving the surface, the dielectric becomes polarized; that ...
Permeation of water through polar and nonpolar polymers and copolymers: determination of the concentration- dependent diffusion coefficient. Journal of Polymer Science, Part B: Polymer Physics 2000; 38: 1998-2008.Marais, S., Nguyen, Q.T., Devallencourt, C., Metayer, M., Nguyen, T.U.,...
Insulators:Nonpolar materials, including certain plastics and polymers, have low electrical conductivity and are used as insulators in electrical and electronic applications. They help prevent the flow of electricity and protect sensitive components from damage. Hydrophobic Coatings:Nonpolar compounds are used...

We can considernatural rubberconsidered as a linear polymer of isoprene (2-methyl-1, 3-butadiene) and is also called as cis - 1, 4 -polyisoprene. ... Both Cellulose and Natural Rubber are linear polymers. Polar and NonPolar Molecules: How To Tell If a Molecule is Polar or Nonpolar ...
The composite can further comprise a nonpolar polymer, such as, a polyolefin polymer, polyethylene, polypropylene, polybutene, polyisobutene, polyisoprene, polystyrene, copolymers thereof and combinations thereof.doi:EP1370489 A1Kenneth O. McElrath...
Therefore, chemical functionalization of GOs is needed for exfoliating in such solvents and for reacting with nonpolar polymers, such as polyethylene (PE) and polypropylene (PP). Two main approaches are typically used for the surface modification of GO, i.e., covalent attachment of functional ...
