Role of Compatibilization in Polymer Nanocomposites

Abstract

Polymeric nanocomposites based on nanoclay, nanosilica, carbon nanotubes, and ceramic or mineral nanoparticles have been developed for a variety of applications. The large surface-to-mass ratios of these particles require good adsorption of the polymeric material on the particle surface to provide the adhesion levels between the filler and matrix resin necessary for improved performance. We review the basic principles underlying these surface interactions and their application in the preparation of a variety of these nanocomposites, as well as in explaining their performance. We demonstrate that the principles underlying the compatibilization of polymer blends and alloys can be successfully used to design nanocomposites and understand their performance.

Thermal, morphological, and X‐ray study of polymer‐clay nanocomposites

“…These are due to occurrence of quasistatic fracture toughness phenomenon valid over small variation of nano filler content between 2 and 5 wt % 40, 41. In a recent review, Kroshefsky et.al 42. have described on the role of nanofillers in polymer nanocomposites with similarity of basic principles used in polymer blend compatibilization where a compatibilizer, either a block or a graft copolymer is commonly used in small concentration(<5 wt %).…”

Progress on Antimicrobial Surgical Gloves: A Review

“…Researchers have found that graphene-based nanomaterials possess excellent antibacterial properties. 46 Although antibacterial materials are widely used in daily life, and the antibacterial properties of nanomaterials are increasingly being explored and developed as commercial products, their cytotoxicity and biocompatibility have raised questions and concerns.…”

Effect of Organophilization and Interlamellar Silylation of Montmorillonite on Compatiblization of Polymer Composites

“…Corrections to D values are essential, this has been done by calculating the intrinsic diffusion coefficient D* from the volume fraction (V r ) of the solvent-swollen rubber, using the relation: (5) Adsorption coefficient is a thermodynamic parameter which depends on the strength of the interactions in the polymer-solvent mixture. (6) where: M ∞ is the mass of solvent taken up at equilibrium and M ○ is the initial mass of polymer sample.…”

“…The lack of miscibility and technological compatibility of the component rubber polymers severely restricts the application of rubber blends. It has been reported the use of nanofillers of inorganic nature for the purpose of compatiblization and reinforcement of incompatible pairs of polymer [5]. Montmorillonite is one of the commercial layered silicates and has been widely used as reinforcing filler in the preparation of nanocomposites [6].…”
