A composition and method of preparing a composition is presented wherein the composition comprises cellulose platelets and the cellulose platelets comprise at least 60% cellulose by dry weight, less than 10% pectin by dry weight and at least 5% hemicellulose by dry weight. The composition can be concentrated to at least 25% by weight solids content by pressing under low pressure, whilst retaining the ability to be re suspended within an aqueous medium. The resulting aqueous medium obtains the desired properties of the composition, such as increased viscosity or increased dispersion of pigment particles, for example, to the same extent as the composition before pressing.

Parts made by additive manufacturing are often structural in nature, rather than having functional properties conveyed by a polymer or other component present therein. Printed parts having piezoelectric properties may be formed using compositions comprising a plurality of piezoelectric particles dispersed in at least a portion of a polymer matrix comprising first polymer material and a sacrificial material, the sacrificial material being removable from the polymer matrix to define a plurality of pores in the polymer matrix. The piezoelectric particles may remain substantially non-agglomerated when combined with the polymer matrix. The sacrificial material may comprise a second polymer material. The compositions may define a composite having a form factor such as a composite filament, a composite pellet, a composite powder, or a composite paste. Additive manufacturing processes may comprise forming a printed part by depositing the compositions layer-by-layer and introducing porosity therein.

The present invention relates to mesostructured particles that have the particular property of being spontaneously individualized, and that include anticorrosion agents. The invention also relates to a process for preparing these particles, and also to materials obtained by inclusion of these particles in matrices.

Disclosed herein are purified surfactant formulations including purified short-chain fluorosurfactant and iodide additive and a two-part coating kit having the same and a silver nanowire formulation.

The present invention relates to gel compositions comprising at least one entrapped active component.

The present invention relates to composition comprising an aqueous dispersion of single phase crosslinked low T.sub.g microspheres and film-forming polyurethane particles. The composition of the present invention is useful as a basecoat layer for a multilayered leather article.

The present invention relates to a method for preparing a multiplicity of containers of paints or pre-paints from separate vessels containing an aqueous solution of a rheology modifier, optionally an aqueous dispersion of an opacifying pigment, an aqueous dispersion of polymer particles, and an aqueous dispersion of organic polymeric microspheres. The process of the present invention provides a simple and cost-effective way of preparing a wide variety of a large quantity of contained and finished paints at point-of-sale.

The present invention relates to microfibrous cellulose capable of exhibiting an excellent dispersibility stability and an excellent coating suitability when added to paint.

To this end, the present invention provides fibrous cellulose having a fiber width of 1,000 nm or less and containing an ionic substituent. An amount of the ionic substituent in the fibrous cellulose is 0.10 mmol/g or more and 1.50 mmol/g or less. A polymerization degree of the fibrous cellulose is 150 or more and 515 or less. When the fibrous cellulose is dispersed in a dispersion solvent containing water and isopropanol to obtain a dispersion fluid having a 7:3 mass ratio of water and isopropanol and a viscosity of 2,500 mPa.Math.s at 23° C., and the dispersion fluid is stirred under predetermined stirring conditions, a viscosity change rate falls within ±50% as calculated by the following formula:

viscosity change rate (%)=(viscosity after stirring−viscosity before stirring)/viscosity before stirring×100

A flexible cellular foam or fabric product is coated with a coating including highly thermally conductive nanomaterials. The highly thermally conductive nanomaterials may be carbon nanomaterials, metallic, or non-metallic solids. The carbon nanomaterials may include, but are not necessarily limited to, carbon nanotubes and graphene nanoplatelets. The highly thermally conductive nanomaterials may include but are not limited to nano-sized solids that may include graphite flakes, for example. When coated on a surface of flexible foam, the presence of nanomaterials may impart greater thermal effusivity, greater thermal conductivity, and/or a combination of these improvements. The flexible foam product may be polyurethane foam, latex foam, polyether polyurethane foam, viscoelastic foam, high resilient foam, polyester polyurethane foam, foamed polyethylene, foamed polypropylene, expanded polystyrene, foamed silicone, melamine foam, among others.
