TL;DR: Homogeneous surface coating of long carbon nanotubes is achieved by in situ polymerization of ethylene as catalyzed directly from the nanotube surface-treated by a highly active metallocene-based complex and allows for the break-up of the native Nanotube bundles leading to high-performance polyolefinic nanocomposites.

TL;DR: In this article, both intercalated and exfoliated poly(L,L-lactide) (P(L-L-LA)/organomodified montmorillonite nanocomposites were synthesized by in situ ring-opening polymerization of L, L-Lactide, in bulk, directly in the presence of the nano-filler.

TL;DR: In this article, high-density polyethylene coated multiwalled carbon nanotubes (c-MWNTs) and multi-walled carbon nanotsubes (MWNT) have been dispersed into an ethylene vinyl acetate (EVA) copolymer by mechanical kneading.

TL;DR: In this paper, multi-walled carbon nanotubes (MWNTs) are placed under atomic nitrogen flow formed through an Ar + N2 microwave plasma in order to functionalize covalently their side walls with nitrogen-containing groups.

Abstract: The use of nanocomposites in textile appli-cations, and in particular of polyurethane (PU) coatingsreinforced by various additives [clay and polyhedral oligo-meric silsesquioxane (POSS)], has grown in recent years.Some interesting results have been obtained, especially withCloisite 30B (a montmorillonite organo-modified by an alkylammonium cation bearing two primary hydroxyl functions):the thermal behavior and the reaction to fire were improved,but the structure (microcomposite, exfoliated, intercalated)was not really determined. This study focuses on polyure-thane coatings reinforced with Cloisite 30B. The interactionsbetween the diisocyanate and the counterions of Cloisite 30Band the structure obtained were demonstrated and dis-cussed. © 2004 Wiley Periodicals, Inc.
