preparation example Construction

[0068] Intercalation / exfoliation of layered materials with the microparticles or nanoparticles of the invention can be effected by any method known in the art for preparing nanocomposites. The order and method of adding the layered materials, microparticles or nanoparticles and optional addenda may vary.

[0069] Materials of the invention comprising layered material and microparticles or nanoparticles with optional addenda may be formed by any suitable method, such as extrusion, coextrusion with or without uniaxial or biaxial orientation, Simultaneous or continuous stretching, blow molding, injection molding, lamination, solvent casting, etc.

[0070] The optional addenda mentioned above may include, but are not limited to, nucleating agents, fillers, plasticizers, impact modifiers, chain extenders, colorants, lubricants, antistatic agents, pigments such as titanium oxide, zinc oxide, mica, Calcium carbonate, dispersants such as fatty acid amides (such as stearamide), metal ...

[0103] Examples 1-3. Insertion of Na Cloisite(R) into P1

[0104] The Na Cloisite(R) and P1 solution were mixed in water for 18 hours at room temperature. A few drops of solution from each mixture were deposited onto individual glass slides and allowed to dry in ambient air. The structure of the solid film formed on the glass sample holder was investigated by X-ray diffraction (XRD). The XRD results are shown in Table 3.

[0108] Examples 4-6, Na Cloisite® inserted into P2

[0109] The clay Na Cloisite(R) was mixed with the polymer colloid solution in water for 24 hours at room temperature, and a few drops of the solution from each mixture were deposited onto separate glass slides and allowed to dry in ambient air. XRD studies the structure of solid films formed on glass sample holders. XRD analysis results are shown in Table 4

[0110] Example

[0111] Compared with the reported (001) basal planar spacing for layered material L1 (Table 2), the basal planar spacing of Examples 4–6 is increased, indicating that intercalation such as intercalation and / or exfoliation has occurred. TEM confirmed these results.

Abstract

Provided is an image forming element having improved mechanical strength and other physical characteristics, and comprising a flexible thermoplastic base. A sprayed material comprises a sprayed layered material with particles having a diameter of <=3 [mu]m. A practicing embodiment includes an article comprising a matrix and the sprayed layered material with a polymer particle dispersed in a medium. A producing method of these materials comprises mixing and grinding particles, and emulsifying the polymer supported in a solvent with a surfactant. As an alternative method, a producing method of a nanocomposite material comprising forming spraying agent particles by incorporating a non-dispersible emulsion polymerization monomer in a medium with a dispersible surfactant in the medium, and then producing the nanocomposite material therefrom, is disclosed.

Description

technical field [0001] The present invention relates to a method for intercalation of layered materials using polymer particles having a diameter of 3 microns or less. Background technique [0002] Over the past decade, the use of inorganic nanoparticles as additives to improve the properties of polymeric materials has been well established. Since the research work at Toyota Central Research Laboratories, polymer-clay nanocomposites have attracted widespread interest in different industrial sectors. The unique physical properties of this nanocomposite are also exploited by these industrial sectors (e.g. automotive industry, packaging industry, plastics industry). These properties include improved mechanical properties such as modulus of elasticity, tension, thermal properties such as linear expansion coefficient and heat deflection temperature, barrier properties such as oxygen and water vapor transmission rates, flame retardancy, ablation, solvent absorption, and the like....
