Polyurethaneacrylate/montmorillonite nanocomposites

Polymer journal, 2021
In order to create polymer nanocomposites with high performance on the basis of polyurethaneacrylates (PUA) with montmorillonite (MMT), three methods of chemical modification of the layered silicate surface have been developed. The first modification method is based on using of two different functional modifiers (organophilic and reactive), the second ...

Implications of silylated montmorillonite on montmorillonite–polyacrylate nanocomposites

Applied Clay Science, 2011
Abstract New nanocomposites based on polyacrylates and five types of montmorillonites modified by edge covalent bonding, were obtained. The alkoxysilanic substituent strongly influenced the physical–chemical properties of the final material. All modified clay minerals exhibit a lower wettability compared to pure montmorillonite.

Stability of Montmorillonites: II. Aberdeen Montmorillonite

Soil Science Society of America Journal, 1971
Abstract Six montmorillonite samples from Aberdeen, Mississippi were equilibrated with various solutions for 3–4 years. Under the conditions of these experiments, Aberdeen montmorillonite was found to be less stable than Belle Fourche montmorillonite and kaolinite.

High-Resolution Electron Microscopy of Montmorillonite and Montmorillonite/Epoxy Nanocomposites

The Journal of Physical Chemistry B, 2005
With the use of high-resolution transmission electron microscopy the structure and morphology of montmorillonite (MMT), a material of current interest for use in polymer nanocomposites, was characterized. Using both imaging theory and experiment, the procedures needed to generate lattice images from MMT were established.

Effect of organophilic montmorillonite on polyurethane/montmorillonite nanocomposites

Journal of Applied Polymer Science, 2003
AbstractDifferent kinds of organophilic montmorillonite cotreated by cetyltrimethyl ammonium bromide (CTAB) and aminoundecanoic acid (AUA) were synthesized and applied to prepare polyurethane/montmorillonite nanocomposites via solution intercalation.

ACID ACTIVATION OF MONTMORILLONITE

Canadian Journal of Chemistry, 1960
A Pembina montmorillonite clay has been activated with sulphuric acid at various dosages by the conventional wet process and by the new "dry" process. The products are compared with respect to the fractions of the metal ion components remaining after leaching, the hydrated silica content, the bleaching capacity, and the B.E.T.

From used montmorillonite to carbon monolayer–montmorillonite nanocomposites

Applied Clay Science, 2014
Abstract Summary background Montmorillonite (Mt) as a low-cost and high-efficient adsorbent for cationic dyes has a promising application in dye wastewater treatment. However, proper disposal of the used Mt is critical to its application. Objective In this work, the used Mt after the adsorption of crystal violet (CV) was calcined under the ...

Biodegradable Polylactide/Montmorillonite Nanocomposites

Journal of Nanoscience and Nanotechnology, 2003
Our continuing research on the preparation, characterization, materials properties, and biodegradability of polylactide (PLA)/organically modified layered silicate (OMLS) nanocomposites has yielded results on PLA/montmorillonite nanocomposites. Montmorillonite (mmt) modified with dimethyldioctadecylammonium cation was used as an OMLS for nanocomposite ...
