Interfacial Polymerization of Cellulose Nanocrystal Polyamide Janus Nanocomposites with Controlled Architectures

Cellulose nanocrystal reinforced oxidized natural rubber nanocomposites.

Natural rubber (NR) latex particles were oxidized using KMnO4 as oxidant to promote the insertion of hydroxyl groups in the surface polyisoprene chains. Different degrees of oxidation were investigated. Both unoxidized and oxidized NR (ONR) latex were used to prepare nanocomposite films reinforced with cellulose nanocrystals (CNCs) by casting/evaporation. The oxidation of NR was carried out to ...

Interfacial Studies of Cellulose Whisker Polymer Nanocomposites

The molecular deformation of cotton cellulose whisker/epoxy resin (CW/EP) and tunicate whisker/poly(vinyl) acetate (TW/PVAc) composites were investigated using Raman spectroscopy. A shift in the 1095 cm Raman peak position is recorded for samples deformed in both tension and compression, which corresponds to the molecular deformation of the cellulose chains within the whiskers. Cyclic molecular...

A viscoelastic response with a finite yield stress is required for filament patterning.[3] The shear-induced alignment of anisotropic building blocks, including carbon fibers,[4,5] silicon carbide whiskers,[5] alumina platelets,[3] and nanofibrillated cellulose (NFC)[6]...

Expandable graphite/polyamide-6 nanocomposites

Polyamide-6 (PA-6)/graphite nanocomposites were prepared by melt blending, using a variety of graphites, including virgin graphite, expandable graphites and expanded graphite. The resulting nanocomposites were characterized by X-ray diffraction, thermogravimetric analysis, cone calorimetry, and tensile mechanical analysis. Nanocomposite formation does occur, as denoted by the nanometre dispersi...
