Polypropylene/Clay Nanocomposites

Abstract

Polymers play a vital role in material science; they have been utilised for more than a century. Cosmetics, geotextiles, aircraft, and automobiles are just a few of the sectors that employ polypropylene. The addition of appropriate clay, can improve the mechanical and barrier characteristics of the material. This chapter deals with various types of fabrication as extrusion process by using twin screw extruder, solution blending method, melt-blending method, in-situ polymerization method, direct melt compounding, ultra sound-aided extrusion and master batch dilution. To characterize the polypropylene/clay nano composites by different property such as mechanical, thermal, tribological, optical, viscoelasticity, viscoplasticity, creep failure, hygrothermal, rheological and morphological.

Perspective Chapter: Nanocomposites – Unlocking the Potentials for Diverse Applications

“…In sectors such as pollutant degradation and aerospace, nanocomposites play vital roles [51]. Bio-renewable/sustainable nanocomposites, synthesized through environmentally friendly methods like plant-mediated synthesis, are gaining popularity [52][53][54]. Innovative techniques like mechanochemistry, flow chemistry, and laser synthesis, along with microwave-assisted methods, advance the preparation of nanomaterials for applications like water purification [55,56].…”

Polypropylene nanocomposites produced by in‐situ grafting of maleic anhydride using different mixing procedures

“…3,4 A large number of studies can be found in the literature dedicated to PP/PPg/oMt NCs following the pioneer ones by Kawasumi et al and Hasegawa et al 5,6 In general, they agree in the fact that the degree of exfoliation/ disaggregation of the clay in PP improves with increasing PP molecular weight, clay cation exchange capacity, size and nature of clay surfactant, and anhydride group (AG) content of PPg for a given PPg/clay ratio. 3,[7][8][9][10][11][12][13][14][15][16] With respect to clay concentration, it has been observed that NCs based in PPg and Mt treated with di-methyl dihydrogenated tallow quaternary ammonium reach percolation at clay concentration between 5 and 9 wt%. 10,13,17 This concentration mainly depends on the molecular weight of PP and PPg, as well as the AG content and concentration of PPg.…”
