Extruded starch–nanoclay nanocomposites: Effects of glycerol and nanoclay concentration

Polymer Engineering & Science, 2007
Abstract Wheat starch‐Cloisite Na+ nanoclay composites containing different glycerol and nanoclay concentrations were extruded using a twin‐screw extruder. X‐ray diffraction and transmission electron microscopy were used to determine the extent of nanoclay dispersion and thermogravimetric analysis was used to characterize thermal ...

Effect of reactive nanoclays on performances of PMMA/reactive nanoclay nanocomposites

Journal of Wuhan University of Technology-Mater. Sci. Ed., 2016
PMMA/reactive nanoclay nanocomposites were prepared by emulsion polymerization using two different reactive nanoclays. X-ray diffraction (XRD) and thermogravimetric analysis (TGA) results confirmed that the reactive nanoclays, kaolinite and montmorillonite, were obtained by the silylation reaction and the double bonds were grafted onto the edges and ...

Nanoclays for Conservation

2019
Within the conservation of artworks materials, this chapter describes innovative strategies based on clay nanoparticles that are promising for protective coating, surface cleaning, and consolidation. We present the preparation of polymer/montmorillonite nanocomposites, which are revealed as efficient protective coatings for highly porous stones ...

Effect of ultrasound sonication in nanoclay clusters of nanoclay/epoxy composites

Materials Letters, 2005
Ultrasound sonication has been widely used in the exfoliation of nanoclay platelets. Nevertheless, the existence of absolutely exfoliated nanoclay composites is impossible in reality. Regions of intercalated nanoclay platelets can be easily formed and agglomerate as tiny clusters.

3D printing of complex GelMA-based scaffolds with nanoclay

Biofabrication, 2019
Photo-crosslinkable gelatin methacrylate (GelMA) has become an attractive ink in 3D printing due to its excellent biological performance. However, limited by low viscosity and long cross-linking time, it is still a challenge to directly print GelMA by ...

Mechanisms of nanoclay-enhanced plastic foaming processes: effects of nanoclay intercalation and exfoliation

Journal of Nanoparticle Research, 2013
The foaming behaviors of high-density polypropylene-nanoclay composites with intercalated and exfoliated nanoclay particles blown with carbon dioxide were examined via in situ observation of the foaming processes in a high-temperature/high-pressure view-cell.

Sustainable and Safer Nanoclay Composites for Multifaceted Applications

Green Chemistry, 2022
Nanoclays, 2D layered mineral silicates, have exceptional physical and chemical (mechanical, thermal, and barrier) properties. Depending on the chemical composition and nanoparticle morphology, nanoclays are organized into several classes ...

Nanoclays as Asphalt-Binder Modifiers

2013
Among the solutions to reduce failures of road pavements, polymer-modified asphalts (PMAs) represent the most effective one and have been adopted worldwide in the last decades. PMAs are blends of asphalt and a polymer, where the latter is swollen by the bituminous material, thus forming a network whose structure closely resembles that of gels ...
