The invention relates to insulating composite materials comprising an inorganic aerogel and a melamine foam. The invention also relates to the production method of said materials, and to the use of same.

Provided is a structure having both fire resistance and heat insulation properties and capable of retaining its shape without being collapsed or deformed even when exposed to a flame. The present invention provides a fire-resistant heat-insulation composition comprising 70 to 250 parts by mass of gypsum based on 100 parts by mass of calcium aluminate having a CaO content of 34% or more, and 0.1 to 20 parts by mass of a fibrous inorganic clay mineral having a crystallization water ratio of 5% or more, based on 100 parts by mass of the total of the calcium aluminate and the gypsum.

The present invention provides a hydrophilic/oleophobic sponge, a preparation method and use thereof, and belongs to the technical field of functional material preparation. In the present invention, a modified solution is obtained by mixing a nanoparticle suspension with a modifier solution; the nanoparticle suspension includes silica-encapsulated Fe.sub.3O.sub.4 nanoparticle suspension and/or nano-silica ethanol suspension; the modifier solution includes chitosan-acetic acid aqueous solution and polyvinyl alcohol (PVA) aqueous solution. The sponge is soaked in the modified solution, mixed and crosslinked with glutaraldehyde aqueous solution to obtain the hydrophilic/oleophobic sponge, conferring good oil-water separation ability on the sponge. The sponge effectively separates a heavy water layer from oil-water mixtures with such light oils as lubricating oil, engine oil, pump oil, crude oil, gasoline, and sunflower seed oil in a simple gravity-driven manner. The hydrophilic/oleophobic sponge prepared by the present invention has good application prospects in oil-water separation.

This disclosure is related to a class of metal-ion induced hydrophobic polymers and method of producing such class of compounds by a one-step solution immersion process. Specifically, a metal-ion Induced hydrophobic polymer or melamine sponge (MII-HMS) is disclosed. Such polymer or sponge is demonstrated to be highly hydrophobic and oleophilic and exhibits excellent oil absorption capabilities, being able to absorb a wide range of oils and organic solvents up to 71 to 157 times of its own weight.

A method of manufacturing a flexible intrinsically antimicrobial absorbent porosic composite controlling for an effective pore size using removable pore-forming substances and physically incorporated, non-leaching antimicrobials. A flexible intrinsically antimicrobial absorbent porosic composite controlled for an effective pore size composited physically incorporated, high-surface area, non-leaching antimicrobials, optionally in which the physically incorporated non-leaching antimicrobial exposes nanopillars on its surface to enhance antimicrobial activity. A kit that enhances the effectiveness of the intrinsically antimicrobial absorbent porosic composite by storing the composite within an antimicrobial container.

A reinforcing sheet including one or more layers of a reinforcing material, and a thermosetting adhesive associated with the reinforcing material, wherein the thermosetting adhesive includes a curing agent, and an epoxy-modified dimerized fatty acid combined with an epoxy terminated polyurethane interpenetrating network.
