Mechanical and Gas Barrier Properties of Polypropylene Layered Silicate Nanocomposites: A Review
Polypropylene owing to its apolar nature suffers from compatibility problems with clay, which is partially polar even after the surface modification with alkyl ammonium ions. To circumvent this limitation, polypropylene nanocomposites have been synthesized by using two methodologies: a) partial polarization of the matrix by the addition of low molecular weight compatibilizer which owing to its ...
متن کاملPolymer-Layered Silicate Nanocomposites: Synthesis, Properties and Applications
Polymer nanocomposites, especially polymerlayered silicate (PLS) nanocomposites, represent a radical alternative to conventionally (macroscopically) filled polymers. Because of their nanometer-size dispersion, the nanocomposites exhibit markedly improved properties when compared with the pure polymers or conventional composites. These include increased modulus and strength, decreased gas permea...
متن کاملStudy on the Optical and Rheological properties of polymer- layered Silicate Nanocomposites
This review reports recent advances in the field of polymer–layered silicate nano composites. Thesematerials have attracted both academic and industrial attention because they exhibit dramaticimprovement in properties at very low filler contents. Herein, the structure, preparation andproperties of polymer–layered silicate nanocomposites are discussed in general, and finally the effectof clay na...
متن کاملSynthesis and Characterization of Recycled Isotactic Polypropylene Nanocomposites Containing Date Wood Fiber
Nanocomposites of isotactic polypropylene (iPP) and date wood fiber were prepared after modification of the host matrix by reactive extrusion grafting of maleic anhydride. Chemical and mechanical treatment of date wood flour (WF) was conducted to obtain nanocrystalline cellulose. Layered silicates (clay) were partially intercalated with date wood fiber, and the modified layered silicate was use...
متن کاملTailored Nanocomposites of Polypropylene with Layered Silicates
The melt rheological properties of layered silicate nanocomposites with maleic anhydride (MA) functionalized polypropylene are contrasted to those based on ammonium-terminated polypropylene. While the MA functionalized PP based nanocomposites exhibit solid-like linear viscoelastic behavior, consistent with the formation of a long-lived percolated nanoparticle network, the single-end ammonium fu...
